Maybe by replacing cat(), e.g., by the use of sink():
sink( "c:/mytest.R")
mytest
sink()
You may want to look at ?dput and ?dget.
However, I doubt that that produces what you really want because only the
body of your function mytest() will be stored in the file, but not the
assignment that created it. Maybe you should store your R-code, i.e., the
assignment in a text file (e.g., using R's editor) to -- later again --
use source() to read that file in and have it executed? See ?source.
