How to rename a file in a different folder within the directory?

I have a file name called 0.pdf, and I want to move this file to a different folder in the same directory called issues. But I also want to keep this 0.pdf in the original place because this file is needed for other functions. I can do the below to move the file to the issues folder.

file.copy("0.pdf","issues")

However, I want to also rename the "0.pdf" in the new folder issues based on a variable value x, if x=5, I want the file name in the issues folder to be 5.pdf for example. How can I do that? If I use file.rename then file.copy, it would get rid of the 0.pdf in the original place. How can I move the file, then rename the file in the new folder?

x=5
file.rename(paste(x,".pdf"))
file.copy(paste(x,".pdf"), "issues")

file.copy takes either a directory path or the full file path as its to argument. So you can write:

file.copy('0.pdf', file.path('issues', paste0(x, '.pdf')))

You can use -

x <- 5
filename <- "0.pdf"
file.copy(filename,paste0("issues/", sub('.*(?=\\.pdf)',x,filename, perl = TRUE)))

sub would replace the filename (without extension) to the value x.

sub('.*(?=\\.pdf)', x, filename, perl = TRUE)
#[1] "5.pdf"
