I'm fairly new to R and am running into some issues exporting multiple graphs from R into a PDF file. The graphs I've created are:
plot(mirt.nom.cohen.pf.fa2,type="info")
plot(mirt.nom.cohen.pf.fa2,type="infotrace")
plot(mirt.nom.cohen.pf.fa2,type="trace")
What would be the most efficient way to export these to a pdf?
Any guidance would be greatly appreciated.
Thank you!

Think of it this way - to save an R graph as a pdf file, you need to:
Open the pdf file;
Place the graph in that file;
Close the pdf file.
What this means in your case is that you have to do something like this:
pdf("plot1.pdf")
plot(mirt.nom.cohen.pf.fa2,type="info")
dev.off()
pdf("plot2.pdf")
plot(mirt.nom.cohen.pf.fa2,type="infotrace")
dev.off()
pdf("plot3.pdf")
plot(mirt.nom.cohen.pf.fa2,type="trace")
dev.off()
The 3 pdf files you created will be stored in R's working directory, which you can find with the command:
getwd()
Once you know where R saved the pdf files, you have to locate that directory on your computer and then you can manually select and open the files. Each file will be single-page and contain one graph.
As already suggested here, you can also create a single, multi-page pdf file which will contain all 3 graphs (one graph per page):
pdf("plot.pdf")
plot(mirt.nom.cohen.pf.fa2,type="info")
plot(mirt.nom.cohen.pf.fa2,type="infotrace")
plot(mirt.nom.cohen.pf.fa2,type="trace")
dev.off()
This file will also be stored in R's working directory.
If you look at the help of the pdf function in R, you'll discover that you can use it with various options (e.g., width and height):
help(pdf)
do you want one to a page, or all on the same page?
to simply get them to a pdf file, you open the pdf device, indicate the file name, and then everything until you close it will go there.
pdf("plots.pdf")
your statements
dev.off()

I have several RMD files in one folder and I need to knit them one by one everyday to get html for each of them. Is there any way or function that I can open them at the same time and knit them by running only few lines code or one function?
did you have a look at this chapter: https://bookdown.org/yihui/rmarkdown/parameterized-reports.html. I think that is exactly what you will need.
How do I create multiple HTML files in a single R markdown file with the Knit HTML option in RStudio? I want to create a separate HTML file with graphs for different levels of a variable in a data frame. I know a similar question has been posted in How to best generate multiple HTML files from RMarkdown based on one dataset?, but I do not manage to get this running.
Could someone give me a simple example, for instance to create 3 HTML files of the mtcars dataset for each amount of cylinders.
data(mtcars)
for(cyl in unique(mtcars$cyl)){
plot.data <- mtcars[mtcars$cyl==cyl,]
plot(plot.data$mpg,plot.data$disp,main=paste(cyl,"cylinders"))
}
This would be of great help for me!
Thanks in advance,

I managed to do the job!
The answer to the post R Knitr PDF: Is there a posssibility to automatically save PDF reports (generated from .Rmd) through a loop? really helped me.
The render function was the solution.
I thought I had to run this type of markdown just through the Knit HTML button, but then only one HTML file is created. The render function can be used in a for loop in R, calling a template.Rmd file to create multiple HTML files.
I've been working with a nice dynamic dataset where I get data from a spreadsheet on GoogleDrive and analyze it in R. No issues there. Is there a way of serving some figures (i.e., some image files) back to GoogleDrive? This can be done in PHP (and Python I imagine). Any idea of whether this can be done directly in R? I.e., given
png(filename = "foo.png")
plot(1:10)
dev.off()
Can I upload foo.png to GoogleDrive from within an R script?
I have an R data frame that I run through knitr using the following code:
knit('reportTemplate.Rnw', 'file.tex') # creates a .tex file from the .Rnw one
texi2pdf('file.tex') # creates a .pdf file from the .tex one
Inside my R script, I want to remove 'file.tex' from my computer folder afterwards. How do I achieve this? It is important that I do this within my .R file, since those lines are actually inside a loop that generates 1000 different reports from that template.
There are a family of functions in R that allow the user to interact with the computer's file system. Run ?files to see functions that make it possible to, for instance, create, rename and remove files.
As noted by Josh O'Brien, in a comment to the OP, in this specific case, the command to be used is file.remove('file.tex').
I need to copy paste R graphs into MS Word.
rando<-rnorm(1:100)
plot(rando)
when I copy the .png graph from R Studio into Word I get a negative space version of the graph:
Is there a cleaner/easier way to do this? I would be happy to use pdf or something else to present the graph.
As #Roland suggested:
Export -> Copy Plot to Clipboard (window with plot will pop-out) -> Metafile -> Copy Plot -> Paste to MSWord.
This seems a lot of clicks to me, rather as #user2633645 suggested save all plots as png then insert them in MSWord in one go.
?png
rando<-rnorm(1:100)
png(filename = "rando.png")
plot(rando)
dev.off()
You can use the devEMF package. It is repeatable, easy to use, and converts very nicely to pdf if needed.
(wow is this an old question, but I guess it's still an issue. I'm on RStudio v1.3.1073)
I came across 3 options:
Cross posting from https://github.com/rstudio/rstudio/issues/5103#issuecomment-679021780: "I've found two simple workarounds: Paste Special and choose TIFF, or (my preference) drag the image from the zoom window and drop in PowerPoint"
Snipping tool
You can specify the dimensions like in the RStudio plot export
windows(800,600) ## Opens graphic window. ctrl c/v works here.
plot(rando)
If you are doing this copy-plot-to-Word often or for several plots, consider creating an .Rmd file with your code, call knitr on that file, and use system("pandoc to convert your knitted .md file to Word.
