[R] lapply() not converting columns to factors (no error message)

[A Singh]

Oh, strange!

I thought it might be a problem with the 'base' package installation, 
because the same thing's worked for me too before but won't do now.

I tried to reinstall it (base), but R says its there already which I 
expected it to be anyway.

I don't quite know where the issue is. Very odd.
