I have one table displaying 3 obs and 4 fields (ID lastname, firstname and telephone number) for each of ID and I prefer to transpose lastname to 3 fields and for firstname field, I want to only keep the one associated with 1st last name and for telephone number, I want to only keep the one associated with 3rd (last) last name.
Table:
ID Lastname FirstName TelephoneNumber
001 Y A 123
001 W B 345
001 Z C 567
002 M D 789
002 N E 912
002 L F 934
Table want:
ID LastName_1 LastName_2 LastName_3 FirstName TelephoneNumber
001 Y W Z A 567
002 M N L D 934
Can anyone help out?
You can do this with PROC SUMMARY IDGROUP. I will leave it to you to research the syntax.
data id;
input (ID Lastname FirstName)(:$3. 2*:$1.) TelephoneNumber;
cards;
001 Y A 123
001 W B 345

For the following data I am trying to filter rows, of each group ID, based on these conditions:
After every row with type='B' and value='Y' do the following
Remove the rows until the next row having type='F' and value='Y'.
If there is no B='Y then keep all of them (e.g. id=002)
Can we create the flag variable as shown in my want dataset? so that I can filter on Flag='Y'?

I tried to do the following
data F;
set have;
where Type='F';run;
data B;
set have;
where Type='B';run;
proc sql;
create table all as select
a.* from B as b
inner join F as f
on a.id=b.id
and b.date >= a.date;
quit;
This includes all the rows from my have dataset. Any help is much appreciated.
The criteria for computing the state of a row as part of a contiguous sub-group (call it a 'run' of rows) within group ID are relatively simple, but a compromised state might occur or be indicated if some funny cases of data occur:
two or more B Y before a F Y (extra 'run ending')
two or more F Y before a B Y ('run starting' within a run)
first row in group not F Y ('run starting' not first in group)
data want(drop=run_:);
SET have;
BY id;
run_first = (type='F' and value='Y');
run_final = (type='B' and value='Y');
* set flag state at criteria for start of contiguous sub-group criteria;
run_flag + run_first;
if first.id and NOT run_flag then
put 'WARNING: first row in group ' id= ' is not F Y, this may be incorrect';
if run_flag > 1 and run_first then
put 'WARNING: an additional F Y before a B Y at row ' _n_;
if run_flag then
OUTPUT;
if run_flag = 0 and run_final then
put 'WARNING: an additional B Y before a F Y at row ' _n_;
* reset flag at criteria for contiguous sub-group;
if last.id or run_final then
run_flag = 0;
run;
Same as Richard, I don't quite understand what the filtering criteria are.
I could see one problem with your join. you used a.* in your select statement, but "b" and "f" as your dataset aliases. this would not work as no dataset have been assigned to alias "a".
Proper way would be as follow:
proc sql;
create table all as
select b.* from B as b
inner join F as f
on b.id=f.id
and b.date >= f.date;
quit;
However, even then, I don't believe inner join is the proper way to solve your problem. Do let us your filtering condition please?
I have a solution but it is not the most elegant (and might not cover corner cases.) If anyone else has a better solution please share.
First, to create the dataset in-case anyone else want to try it out:
Data work.have;
input #01 ID 3.
#05 Type $1.
#07 Date date7.
#18 Value $1.;
format ID 3.
Type $1.
Date date11.
Value $1.;
datalines;
001 F '02Jan18'n Y
001 B '03Jan18'n
001 B '04Jan18'n Y
001 B '05Jan18'n
001 B '06Jan18'n
001 F '06Jan18'n Y
001 B '06Jan18'n
001 B '07Jan18'n
001 B '08Jan18'n Y
001 B '08Jan18'n
001 B '09Jan18'n
002 F '02Jan18'n Y
002 B '03Jan18'n
002 B '04Jan18'n
;
run;
Solution:
I based on your edited suggestion of creating a flag variable.
Data Flag;
set work.have;
if Type = 'B' and Value = 'Y' then
flag + 1;
if Type = 'F' then
flag = 0;
if Value ne 'Y' and flag = 1 then delete;
run;
The flag variable is 0 by default.
The first IF-Then condition identifies the Type B ='Y' rows and flag them as 1, as well as retaining this flag for the subsequent rows.
The second IF-Then condition identifies the type='F' row and resets the Flag to 0
The Last If-Then condition drops all rows with Flag=1 except the first occurrence which are the Type B ='Y' rows.
I hope this applies to your problem.
I am trying to count number of times all the values appear in the entire dataset. So I want a table/output with values - # of times it appears in the dataset. I have used proc sql, proc freq without any luck.
data Data1;
input xx yy zz;
datalines;
123 456 234
456 123 345
234 345 123
;
run;
Want a table output with 123 - 3, 234 - 2, etc.
The easiest option (I think) is to create a dataset that puts all the values in a single column, then you can just run a proc freq off that.
data have;
input xx yy zz;
datalines;
123 456 456
456 123 234
234 234 123
;
run;
data single_column;
set have;
array vars{*} xx yy zz;
do i = 1 to dim(vars);
all_vals = vars{i};
output;
end;
keep all_vals;
run;
proc freq data=single_column;
table all_vals / out=want;
run;
The problem said: The first line is a header line and should not be read (use the infile option firstobs=2) The remaining lines contain and ID number(character). gender(character), date of birth DOB, and two scores 1 and 2. Note that there are some missing values for the scores, and you want to be sure that SAS does not go to a new line to read these values. Write a SAS DATA STEP TO READ DOB with DATE9. Here are the lines of data(I put it in my code to save space).
DATA READ;
INFILE DATALINES FIRSTOBS=2;
INPUT ID 1-3
GENDER $ 5
#7 DOB mmddyy10.
# SCORE1 3
# SCORE2 3
;
DATALINES;
***Header line: ID GENDER DOB SCORE1 SCORE2
001 M 10/10/1976 1OO 99
002 F 01/01/1960 89
003 M 05/07/2001 90 98
;
DATA PROB12_8;
SET READ;
FORMAT DOB MMDDYY9.;
RUN;
PROC PRINT DATA=PROB12_8;
RUN;
My output is:
OBS ID GENDER DOB SCORE1 SCORE2
1 1 M . . 99
2 2 F . 89 .
3 3 M . 90 98
I don't understard why the program read in that way, if I specify the amount of spaces and use the pointer in my program.
Thanks for your help.
Your problems start at SCORE1 and SCORE2 you have the pointer control specified incorrectly. Also notice that 1OO is not 100. This file can be read easily with list input and missover infile statement option.
DATA READ;
INFILE DATALINES FIRSTOBS=2 missover;
informat id $3. gender $1. dob mmddyy10.;

I have a dataset that looks something like this:
IDnum State Product Consumption
123 MI A 30
123 MI B 20
123 MI C 45
456 NJ A 15
456 NJ D 10
789 MI B 60
... ... ... ...
And i would like to create a new dataset, where i have one row for each IDnum, and a new dummy variable for each different product (in my real dataset i have close to 1000 products), along with it's associated consumption. It would look like something in these lines
IDnum State Prod.A Cons.A Prod.B Cons.B Prod.C Cons.C Prod.D Cons.D
123 MI yes 30 yes 20 yes 45 no -
456 NJ yes 15 no - no - yes 10
789 MI no - yes 60 no - no -
... ... ... ... ... ... ... ... ... ...
Some variables like "State" doesn't change within the same IDnum, but each row in the original bank are equivalent to one purchase, hence the change in the "product" and "consumption" variables for the same IDnum. I would like that my new dataset showed all the consumption habits of each costumer in one single row, but so far i have failed.
Any help would be greatly apreciated.
Without yes/no variables, it's really easy:
data input;
length State $2 Product $1;
input IDnum State Product Consumption;
cards;
123 MI A 30
123 MI B 20
123 MI C 45
456 NJ A 15
456 NJ D 10
789 MI B 60
;
run;
proc transpose data=input out=output(drop=_NAME_) prefix=Cons_;
var Consumption;
id Product;
by IDnum State;
run;
Adding the yes/no fields:
proc sql;/* from column names or alternatively
create it from source data directly if not taking too long */
create table work.products as
select scan(name, 2, '_') as product length=1
from dictionary.columns
where libname='WORK' and memname='OUTPUT'
and upcase(name) like 'CONS_%';
quit;
filename vars temp;/* write a temp file containing variable definitions
in desired order */
data _null_;
set work.products end=last;
file vars;
length str $40;
if _N_ = 1 then put 'LENGTH ';
str = catt('Prod_', product, ' $3');
put str;
str = catt('Cons_', product, ' 8');
put str;
if last then put ';';
run;
options source2;
data output2;
length IdNum 8 State $2;
%include vars;
set output;
array prod{*} Prod_:;
array cons{*} Cons_:;
drop i;
do i=1 to dim(prod);
if coalesce(cons(i), 0) ne 0 then prod(i)='yes';
else prod(i)='no';
end;
run;
In the following SAS statement, what do the parameters "noobs" and "label" stand for?
proc print data-sasuser.schedule noobs label;
per SAS 9.2 documentation on PROC PRINT:
"NOOBS - Suppress the column in the output that identifies each observation by number"
"LABEL - Use variables' labels as column headings"
noobs don't show you the column of observations number
(1,2,3,4,5,....)
