R help - Aug 2009 - Appending strings at the beginning of a text file

Dear All,

I have a piece of text that I want to append to a text file at the
beginning of the text file.

I have thought about using cat() with the option 'append=T', but the
appending, in this case, is done at the bottom of the text file. Any
ideas?

Thanks in advance,

Paul

Try this;

fConn <- file('test.txt', 'r+')
Lines <- readLines(fConn)
writeLines(paste("Text at beginning of file", Lines, sep =
"\n"),
           con = fConn)
