That will not work (or at least doesn't work for me.

This does work:

fnam<-'thefilename.csv'  #or build the name however you like
fpath <- 'macintoshhd/users/me/myfolder/  # or whatever you need

read.csv(eval(paste(fpath,fnam,sep=""))  #worked for me

Try this:

read.csv(sprintf("D://R//Data//%04d//%04d.csv", x, x), header = TRUE)
