Re: [R] Appending strings at the beginning of a text file

Henrique, With paste(), it works only if the file has only one line; otherwise, "Text at beginning of file" is repeated after each line of the file. Paul On Wed, Aug 26, 2009 at 2:03 PM, Henrique Dallazuanna wrote: > It works with paste, but I forgotten the close(fConn) after the writeLines.
