I'm working on a report in R markdown.
I know there is a way to have different plots side by side, and there is also a way to have different images side by side.
But is it also possible to show a plot and an image side by side?
I have a ggplot bar graph that I would like to present next to an image of a map, it takes up too much space if I put the image below the graph.
Thanks,
Regards,
Freya
This could work to you. Here is the step by step, with an indication of the code between parentheses.
First, you need to load the image (y), by creating an object (photo).
Second, you create a ggplot with the image (photo_panel).
Finally, after creating your plot (p1), you use the library cowplot to plot a grid (plot_grid).
.Rmd file:
---
title: "Image + graph"
author: bttomio
output: pdf_document
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = FALSE)
```
## R Markdown
```{r image_graph}
y = "http://upload.wikimedia.org/wikipedia/commons/5/5d/AaronEckhart10TIFF.jpg"
download.file(y,'y.jpg', mode = 'wb')
library("jpeg")
photo <- readJPEG("y.jpg",native=TRUE)
library(ggplot2)
library(cowplot)
photo_panel <- ggdraw() + draw_image(photo, scale = 0.8)
df <- data.frame(Years=rep(2016:2017, each=4),
Quarters=rep(paste0("Q", 1:4), 2),
Series1=seq(100, 800, 100))
library(ggplot2)
p1 <- ggplot(df) +
geom_point(aes(x=Quarters, y=Series1)) +
facet_wrap( ~ Years, strip.position="bottom", scales="free_x") +
theme(panel.spacing=unit(0, "lines"),
strip.background=element_blank(),
strip.placement="outside",
aspect.ratio=1) # set aspect ratio
plot_grid(p1, photo_panel, ncol = 2)
```

I have the following rmd script. I've spent a few days trying to get this to work but I am failing miserably. Basically I need help with three things. I am happy to post three separate questions if needed.
The multicolumn options/code are completely ignored. The corporatetable.docx is in landscape and has a typical corporate style. I need to have a full width landscape -> two column landscape -> full width landscape. If I could get the two column landscape setup to work, the remaining style would be inherited by corporatetable.docx. If I could get help with only one - I would need this.
When I run the rmd it generates a word file but none of the corporate styles are in there. It just uses my word's default colors etc. The difference is very clear - no landscape, single column and blue instead of red. How do I correctly pass the officedown::rdocx_document: to reference my word file because it's clearly not picking it up and no warning or error is generated?
If you see in the second chunk I am using flextable to show two pictures (which are passed through params) in the word report and align them with some information. myft works but it prints the (temporary/volatile) path instead of showing the pictures in the report. For reference if I use knitr::include_graphics(c(params$x1,params$x2)) it works fine.
I'm really stuck on these. Any help is welcome.

I am trying to develop my class lecture slides using Shiny apps and ioslides. I would like to have several Shiny apps, each on a different slide to illustrate different concepts. When I naively write the input and render code for an app on a slide, only the first app works and the succeeding apps do not work.
Do I have to shut down the first app before starting the second (and so forth)? I can't seem to find an answer anywhere and I hope someone here can lead me in the right direction. Thanks, in advance.
I had the same problem recently and what you have to avoid its to think you are making differente shiny app in the same presentation, because the hole documen its a shiny runtime. Here you do not have to create explicitly the objects "ui" and "serve"
Look at this example to see if you can get the idea

## first slide
```{r}
fluidPage(
# Application title
titlePanel("Old Faithful Geyser Data"),
# Sidebar with a slider input for number of bins
sidebarLayout(
sidebarPanel(
sliderInput("bins",
"Number of bins:",
min = 1,
max = 50,
value = 30)
),
# Show a plot of the generated distribution
mainPanel(
plotOutput("distPlot")
)
)
)
```
```{r}
output$distPlot <- renderPlot({
# generate bins based on input$bins from ui.R
x <- faithful[, 2]
bins <- seq(min(x), max(x), length.out = input$bins + 1)
# draw the histogram with the specified number of bins
hist(x, breaks = bins, col = 'darkgray', border = 'white')
})
```
## next slide
#The other app you want toy show, just the way i did it in the first slide
I have a shiny app created with Rmd / Flexdashboard with many charts and tables. It is working well. Recently, I started using shiny_prerendered to improve the UX during startup. Now the page loads up faster but all the sections are empty (this is expected - the html renders but the charts and tables are still waiting for data) until the server code runs.
Is it possible to have some placeholder data during setup that will load the shiny output? Reactive outputs are not recognized in the setup context. Is this what the server-start context is for? I have tried too that without success?
Here is a simple code with a two value boxes
---
title: "ValueBoxTest"
output:
flexdashboard::flex_dashboard:
vertical_layout: fill
theme: united
runtime: shiny
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE, options(scipen = 1, digits = 2))
### load packages
```
# ValueBox Test
===============================================
## Row 1
### Box 1
```{r, context="server"}
output$value1 <- renderValueBox({
### p <- 100 starting value placeholder
### call function to generate "p"
p <- functionToGenerateValue()
valueBox(p, icon = "fa-usd")
})
```
```{r echo = FALSE}
valueBoxOutput("value1")
```
## Row 2
### Box 2
```{r, context="server"}
output$value2 <- renderValueBox({
### q <- 0 starting value placeholder
### call function to generate "q"
q <- functionToGenerateValue()
valueBox(q, icon = "fa-usd")
})
```
```{r echo = FALSE}
valueBoxOutput("value2")
Well, it may be simpler than you might think. For example, why don't you try to change from runtime:shiny to runtime:shiny_prerendered? It may do the trick.
I am working in RStudio and creating a markdown Shiny presentation (which I believe uses IOslides).
Currently the generated presentation doesn't have any navigational help, the user has to know they need to use left/right arrows to move to the next or previous slides. Even when deployed to server I don't see any arrows at the bottom of presentations.
I have searched through documentation and here to see if this is possible, but can't seem to find anything.
Is there some setting to include a Previous/Next type link at the bottom of every slide?
Process to create my presentation in R Studio:
New file > R Markdown > Shiny > Shiny presentation
The issue occurs even with the sample code when creating a new file - there are no navigation arrows
Published example (where there are no navigation arrows):
https://regolith.shinyapps.io/test
And the sample code (as generated by R studio):
---
title: "test"
author: ""
date: "24 January 2017"
output: ioslides_presentation
runtime: shiny

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = FALSE)
```
## Shiny Presentation
This R Markdown presentation is made interactive using Shiny. The viewers of the presentation can change the assumptions underlying what's presented and see the results immediately.
To learn more, see [Interactive Documents](http://rmarkdown.rstudio.com/authoring_shiny.html).
## Interactive Plot
```{r eruptions}
inputPanel(
selectInput("n_breaks", label = "Number of bins:",
choices = c(10, 20, 35, 50), selected = 20),
sliderInput("bw_adjust", label = "Bandwidth adjustment:",
min = 0.2, max = 2, value = 1, step = 0.2)
)
renderPlot({
hist(faithful$eruptions, probability = TRUE, breaks = as.numeric(input$n_breaks),
xlab = "Duration (minutes)", main = "Geyser eruption duration")
dens <- density(faithful$eruptions, adjust = input$bw_adjust)
lines(dens, col = "blue")
})
```

## R Output
```{r cars}
summary(cars)
```
I am using RStudio to write my R Markdown files. How can I remove the hashes (##) in the final HTML output file that are displayed before the code output?
As an example:
---
output: html_document
---
```{r}
head(cars)
```
You can include in your chunk options something like
comment=NA # to remove all hashes
or
comment='%' # to use a different character
More help on knitr available from here: http://yihui.name/knitr/options
If you are using R Markdown as you mentioned, your chunk could look like this:
```{r comment=NA}
summary(cars)
```
If you want to change this globally, you can include a chunk in your document:
```{r include=FALSE}
knitr::opts_chunk$set(comment = NA)
```
Just HTML
If your output is just HTML, you can make good use of the PRE or CODE HTML tag.
Example
```{r my_pre_example,echo=FALSE,include=TRUE,results='asis'}
knitr::opts_chunk$set(comment = NA)
cat('<pre>')
print(t.test(mtcars$mpg,mtcars$wt))
cat('</pre>')
```
HTML Result:
Welch Two Sample t-test
data: mtcars$mpg and mtcars$wt
t = 15.633, df = 32.633, p-value < 0.00000000000000022
alternative hypothesis: true difference in means is not equal to 0
95 percent confidence interval:
14.67644 19.07031
sample estimates:
mean of x mean of y
20.09062 3.21725
Just PDF
If your output is PDF, then you may need some replace function. Here what I am using:
```r
tidyPrint <- function(data) {
content <- paste0(data,collapse = "\n\n")
content <- str_replace_all(content,"\\t"," ")
content <- str_replace_all(content,"\\ ","\\\\ ")
content <- str_replace_all(content,"\\$","\\\\$")
content <- str_replace_all(content,"\\*","\\\\*")
content <- str_replace_all(content,":",": ")
return(content)
}
```
Example
The code also needs to be a little different:
```{r my_pre_example,echo=FALSE,include=TRUE,results='asis'}
knitr::opts_chunk$set(comment = NA)
resultTTest <- capture.output(t.test(mtcars$mpg,mtcars$wt))
cat(tidyPrint(resultTTest))
```
PDF Result
PDF and HTML
If you really need the page work in both cases PDF and HTML, the tidyPrint should be a little different in the last step.
```r
tidyPrint <- function(data) {
content <- paste0(data,collapse = "\n\n")
content <- str_replace_all(content,"\\t"," ")
content <- str_replace_all(content,"\\ ","\\\\ ")
content <- str_replace_all(content,"\\$","\\\\$")
content <- str_replace_all(content,"\\*","\\\\*")
content <- str_replace_all(content,":",": ")
return(paste("<code>",content,"</code>\n"))
}
```
Result
The PDF result is the same, and the HTML result is close to the previous, but with some extra border.
It is not perfect but maybe is good enough.
