There is no fundamental difference between an .R file and a .txt
file. They are both just text files; all you are doing is changing
the name. This Stack Overflow question shows how to use
`file.rename` to do
so. http://stackoverflow.com/a/10759083/1850696.

Dear all,
I am a beginner in R and want to ask a simple question. I have a
code file in text format which I need to change to .r format
only. For example now it is RHtestsV4.r.txt which needs to be
changed to just RHtestsV4.r. I tried this
sub("^([^.]*).*", "\\1", 'RHtestsV4.r.txt') [1] "RHtestsV4"
But this didn't seem to work as again when I try to call the
function using source("RHtestsV4.r") The error message is
Error in file(filename, "r", encoding = encoding) :
cannot open the connection
In addition: Warning message: In file(filename, "r", encoding =
encoding) :
cannot open file 'RHtestsV4.r': No such file or directory
I think it is due to the format of the file. Please help me to
convert the file to .r format.
Thanks Som
