I am trying to read numeric data from the file. But I am to read it properly the output that I am getting from my SAS program is attached. I recently started learning SAS programming.
I am using SAS University Edition on the windows machine. I already tried by reading data in character as well as numeric formate.
data ds;
infile '/folders/myshortcuts/my_folder/exrate.sas7bdat';
input s ;
run;
I am expecting the same table to be as an output result.
Data File
Output
There are 3 things you need to do:
Make sure that the folder you put the dataset in is accessible to the SAS University Edition VM. Did you follow the setup guide in full? Usually that directs you to set up a folder that becomes available within the VM as /folders/myfolders
Assign a library pointing to the folder using a libname statement.
Use a set statement to access the dataset, not an infile statement. The latter is for reading raw data like csv files.
The sas code should look like this:
libname mylib "/folders/myfolders"; /*Change this to point to your folder path if you're sure you've got the right one*/
data ds;
set mylib.exrate(keep = s);
run;

I've large txt file stored in sas enterprise guide(sas is connected to Winscp this is where th txt file is stored). How to read it and convert it to sas data as output.
When I check in SAS community I've get the code sample to read txt file (see bellow) is it same to read txt stored in sas?
proc import datafile='path'
out=NAME
dbms=dlm
replace;
datarow=5;
delimiter='09'x;
run;
There is another method I see also which use infile.
Which method shoul I use for me case?
I’ve not tried any method yet. Because I do not understand parameters. the path should it be the one in sas (in server) or in winscp?
Proc IMPORT works only on operating file 'references' that deliver the file directly.
WinSCP is a ftp client, so you two options:
Use WinSCP to copy the remote file to the local operating system, then you can use IMPORT or DATA step with INFILE
Use filename FTP access method and DATA step that reads data lines retrieved by SAS FTP engine
filename offsite ftp 'remote-filename` user=… pass=… host=… cd=… ;
data gotit;
infile offsite;
input var1 var2 var3 etc … ;
run;
The specific input statement might need informats and pointer control options, all dependent on the data file layout. Other infile options might be needed depending on field delimiters and content.
I have to perform statistical analysis on a file with hundreds of observations and 7 variables(columns)on SAS. I know that it is necessary to insert all the observations after "cards" or "datalines". But I can't write them all obviously. How can I do? Moreover, the given data file already is .sas7bdat.
Then, since (in my case) the multiple correspondence analysis requires only six of the seven variables, does this affect what I have to write in INPUT or/and in CARDS?
You only use CARDS when you're trying to manually write a data set. If you already have a SAS data set (sas7bdat) you can usually use that directly (there are some exceptions but likely don't apply here).
First create a libname to the folder where the file is:
libname myFiles 'path to fodler with sas file';
Then load it into your work library - this is a temporary space that is cleaned up when you're done so no files here are saved permanently.
This copies it over to that library - which is often faster.
data myFileName;
set myFiles.myFileName;
run;
You can just work with the file from that library by referencing it as myFiles.myFileName in your code.
proc means data=myFiles.myFileName;
run;
This should get you started, but you should take the SAS free e-course to understand the basics, it will save you time overall.
Just tell SAS to use the dataset. INPUT statement (and CARDS/DATALINES or INFILE statement) are for reading from text files.
proc corresp data='/my directory/mydataset.sas7bdat' .... ;
...
run;
You could also make a libref that points to the directory and use two level name to reference the dataset.
libname myfiles '/my directory/';
proc corresp data=myfiles.mydataset .... ;
...
run;
I've scoured the internet but cannot seem to figure this out. My question is, if I have a sas7bdat file, how can I read a sas7bdat file in SAS studio so that I can work with it.
I've tried:
libname test 'C:\Users\name\Downloads\test.sas7bdat';
which gives me the error that library test does not exist and if I try the following, I know that I need an INPUT which I don't know of unless I can see into the file.
DATA test;
INFILE 'C:\Users\lees162\Downloads\test.sas7bdat';
RUN;
Is there something I'm missing?
Libref's that you create via the LIBNAME statement point to directories, not individual files.
libname test 'C:\Users\name\Downloads\';
INFILE is for reading raw data files. To reference an existing SAS dataset you use a SET statement (or MERGE,MODIFY,UPDATE statement).
set test.test ;
Note that you can skip defining a libref and just use the quoted physical name in the SET statement.
DATA test;
set 'C:\Users\lees162\Downloads\test.sas7bdat';
RUN;
Of course to use C:\ in the paths this is assuming that you are using SAS/Studio to point to full SAS running on your PC. If you are using SAS University Edition then it is running in a virtual machine and you will need to put the SAS dataset into a folder that is mapped to the virtual machine and then reference it in the SAS code with the name that the virtual machine uses for the directory.
So something like:
DATA test;
set '/folders/myfolders/test.sas7bdat';
RUN;
Libname is just pointing the location and once you have done that you can use that libname followed period and dataset in your set statement
libname test "C:\Users\name\Downloads";
DATA test;
set test.asl;
RUN;
One possible reason could be that you are using the SAS University edition (It doesn't support variable library address).
From one of the SAS community Q/A:
"When you are using the SAS University Edition, any libraries that you create must be assigned to a shared folder. You access your shared folder with this pathname: /folders/myfolders/. Always use '/' in the directory path, even in Windows operating environments"
After setting the directory address, proceed as instructed by Tom above in one of the answers.
Suppose you have the sas dataset at location. C:\Users\name\Downloads\test.sas7bdat
libname download 'C:\Users\name\Downloads';
proc sql;
select * from downloads.test;
run;
you can read your dataset like a table using the proc sql, in case you want to query the dataset, but if you want to modify the existing dataset then you can use the data setp as mentioned by #krian.
I'm trying to move a SAS dataset over to our Linux server from a client. They created it on SAS 9.4, 64-bit on Windows 7. I'm using SAS 9.4, 64-bit on Linux.
If I do
proc datasets library=din;
run;
I get the following in my log
Libref DIN
Engine V9
Physical Name /sasUsr/DM/DATA/SAS_DATA/201510_SSI
Filename /sasUsr/DM/DATA/SAS_DATA/201510_SSI
Inode Number 46358529
Access Permission rwxrwxr-x
Owner Name cvandenb
File Size (bytes) 4096

# Name Type Size Last Modified
1 SAMPLE_FROM_SSI DATA 131072 09/14/2015 17:07:01
2 TEST DATA 131072 09/15/2015 09:35:59
15 run;
but when I do
data test;
set din.sample_from_SSI;
run;
I get
18 data test;
19 set din.sample_from_SSI;
ERROR: File DIN.SAMPLE_FROM_SSI.DATA does not exist.
20 run;
I also created a dummy dataset din.test and was able to proc print it. This seems to either be a version compatibility issue or transmission issue. I thought this would be straightforward. Any suggestions? I'm moving the file from windows to Linux with WinSCP. I'd rather not have to request a .csv and create the input statement, but will if I have to. Your help is appreciated.
Thanks,
Cory
If you are talking about an actual SAS dataset then make sure that the name of the file is in all lowercase letters and has the extension of .sas7bdat. If the source file from Windows did not have an extension of .sas7bdat then perhaps you are not dealing with a SAS dataset, but some other type of file.
In SAS code it does not matter whether you reference a dataset using upper or lower case letters. So you can reference a datasets as sample_from_SSI or Sample_From_Ssi to refer to the same file. The same is true of general filenames on a Windows machine. But on Unix system file names with different use of upper and lower case letters are distinct files. SAS requires that the filename of a SAS dataset must be in all lowercase letters.
So if you write:
libname DIN '/sasUsr/DM/DATA/SAS_DATA/201510_SSI';
proc print data=DIN.SAMPLE_FROM_SSI;
run;
Then you are looking to make a listing of the data in a file named:
/sasUsr/DM/DATA/SAS_DATA/201510_SSI/sample_from_ssi.sas7bdat
I usually get a note about CEDA in this case not missing data.
Create either a CPORT or XPORT file using the associated proc, PROC CPORT or XPORT and then move that file.
Try referring to the data with all caps as well, which I don't think should be the issue, but is possible.
I would try using PROC COPY directly on the libname, as you can select memtype=data that way without explicitly specifying the file.
If SAS still can't do that, then you might have a permissions issue or something else that is outside of the SAS realm I suspect.
Try using PROC CPORT and PROC CIMPORT.
Use the CPORT Procedure to convert the file into a transport file.
Use the CIMPORT Procedure to convert the transport file to a SAS format.
There is an example that sounds similar to what you are doing here.
According to SAS, the general procedure is:
A transport file is created at the source computer using PROC CPORT.
The transport file is transferred from the source computer to the target computer via communications software or a magnetic medium
The transport file is read at the target computer using PROC CIMPORT.
Note: Transport files that are created using PROC CPORT are not
interchangeable with transport files that are created using the XPORT
engine.
If that doesn't work, or it is taking a very long time to figure out, it would be faster to ask them for a CSV and import it directly using PROC IMPORT. It should read in quite easily, especially if it comes from PROC EXPORT.
I need to import data from European Social Survey databank to SAS.
I'm not very good at using SAS so I just naively tried importing the text file one gets but it stores it all in one variable.
Can someone maybe help me with what to do? Since there doesn't seem to be a guide on their webpage I reckon it has to be pretty easy.
It's free to register (and takes 5 secs) and I need all possible data for Denmark.
Edit: When downloading what they call a SAS file, what i get is a huge proc format and the same text file as one gets by choosing text.
The data in the text file isn't comma separated and the first row does not contain variable names.
Download it in SAS format. Save the text file in a location you can remember, and open the SAS file. It's not just one big proc format; it's a big proc format followed by a datastep with input code. It was probably created by SPSS (it fits the pattern of an SPSS saved .sas file anyhow). Look for:
DATA OUT.ESS1_4e01_0_F1;
Or something like that (that's what it is when I downloaded it). It's probably about 3/4 of the way down the page. You just need to change the code:
INFILE 'ESS1_4e01_0_F1.txt';
or similar, to be the directory you placed the text file in. Create a LIBNAME for OUT that goes to wherever you want to permanently save this, and do that at the start of the .sas file, replacing the top 3 lines like so.
Originally:
LIBNAME LIBRARY '';
LIBNAME OUT '';
PROC FORMAT LIBRARY=LIBRARY ;
Change these to:
libname out "c:\mystuff\"; *but probably not c:\mystuff :);
options fmtsearch=(out);
proc format lib=out;
Then run the entire thing.
This is the best solution if you want the formatted values (value labels) and variable labels. If you don't care about that, then it might be easier to deal with the CSV like Bob shows.
But the website says yu can download SAS format, why don't you?
You need a delimiter if all goes into one column.
data temp;
length ...;
infile 'file.csv' dlm=',';
input ...;
run;
As Dirk says, the web site says you can download a SAS dataset directly. However, if there's some reason you don't want to do that, choose a comma separated file (CSV) and use PROC IMPORT. Here is an example:
proc import out=some_data
datafile='c:\path\somedata.csv'
dbms=csv replace;
getnames=yes;
run;
Of course, this assumes the first row contains column names.
