[R] Can any one help me on this Issue

[R. Michael Weylandt]

Hi Namit,

I feel like you posted this (or a _very_ similar) question just a few
days ago: yes.... indeed you did:

https://stat.ethz.ch/pipermail/r-help/2012-July/319634.html

with a good amount of response.

I'm going to direct you in a different path: don't add these things
within R, at least, not to the very end. Your numbers are truly just
numbers; dollar signs and percent symbols are just typographical cruft
that humans like to see -- not computationally relevant, but
admittedly quite useful -- so add them on in making your final report
(in Sweave / LaTeX or other)

Your upstream problems seems to be that you have factors and not
numbers in your data frame. You'd be better served trying to find the
cause of that -- str() is helpful -- and, if you can fix that, all
your warning message should take care of themselves.

Best,
Michael
