Someone may know a way. However its certainly possible to execute a command in
linus from R. So you can ls the file (in windows try dir) and see if it
exists, and build a loop round that.
Just bew3are it'll be quick if there is only 1 file. If you have 9999 files it
may slow things down a bit!
Here's my example...
#Example script to check if a file exists (linux system)
filename = "somefile"
fileno = 0
extension= ".pdf"
path="/home/user/"
repeat
{
fullfile= paste(path,filename,fileno,extension, sep="")
if (length (system(paste("ls",fullfile), intern = T)) == 0) break
fileno<-fileno+1
}
#your command to save the file... using 'fullfile' as the filename and path
