[R] Suppress 'x' when appending to a csv file

[John Kane]

Is there any convenient way to supress the x that
appears in csv export files?  I would like to be able
to export a file and add a comment to it yet still be
able to read it back into R.  I don't see any way to
get rid of the x that seperates the different appended
parts.

Thanks
