I put five data files (example1.dat, example2.dat, example3.dat,
example4.dat, example5.dat, example6.dat) in my working directory.

Hello,
I would like to rename multiple files in a directory. Filenames are read using:
lfile <- list.files(pattern="rcp45_Daily_")
files <- paste(paste(getwd(),lfile,sep="/"), list.files(lfile),sep="/")# getwd
of these files
dput(lfile)
c("rcp45_Daily_Sim001.dat", "rcp45_Daily_Sim002.dat")
- How can I rename these files (200 in number) using something like:
file.rename(lfile, paste0("rcp45_Daily_Sim", 1:200))?The new filenames
should be rcp45_Daily_Sim001, rcp45_Daily_Sim002, ..., rcp45_Daily_Sim200.
- I would like to write the new file names to the directory.
The data files contain huge amounts of data and should not be read into R. Only
the file names should change.
Many thanks for your helpful answers.
Asong.
