[R] rename files in R

The syntax might not be quite right, but why not something like
file.rename(colnames(dataframe)[1]) -- Using colnames to get the names of the
columns that are in the first row, selecting the first element from colnames()
and setting the file name equal to that.

Do a for loop using current file names in some folder, and save to a new folder.

Subject: Re: [R] rename files in R

[External Email]

 Hello,Here is the example:
  file name    first row  file1.txt     abc.txt  file2.txt     bed.txt
file3.txt     gogo.txt  . . file1243.txt    last.txt
I want to use loop because I need to read the first row information for first
file, and then rename the file, then go to next file. I'm not sure if this
is right way to approach my goal. Any suggestion will be appreciated. Thanks,

 Hello,

Please post the first row of 2 or 3 files and the expected result.

You can rename files with ?file.rename. This function is vectorized its on
arguments so you do not need a loop, only the source and destination filenames.
Both vectors should have the same length, if not strange things will occur
including data loss.

Hope this helps,
