[R] name a file using the time on Windows

Question

I want to save the R output to a specific place, but what I want to do is add the time and day to the file(according to the system time).

29-Jul-2010 15.35.txt

anyway to do it?

I know about Sys.time and date() but they both contain : which windows xp doesn't like.

Answer 1

gsub(":",".",Sys.time())

Answer 2

use format to remove the colons and put in dashes for separtors.

format(Sys.time(), "%Y-%m%-%d %H-%M-%S")
