R-language file, yes

No.

> I want to use this function to read a table in a data file like this

> x y z
> #my data begin here
> 1 2 3

> 1 0 1

Pre-process them with e.g. Perl to remove the comment lines, or
even with R itself (read in the lines, remove those starting with #,
write them out to a temp file and call read.table on the temp file).
