R doesn't currently have a translation team (see 
translation.r-project.org) for Urdu, so it may be hard for you to get 
Urdu-specific support.  However, I would guess the problems you are 
having are common to other languages that use non-Roman alphabets, and 
you may get some advice from the translation teams for one of them.

The general issues that I know of are:

  - R needs to know your encoding.  On Unix-alikes the best support is 
for UTF-8; Windows support is weaker, because Windows tends to use 
UTF-16 or other multibyte encodings, and R's support for those is mixed.

  - You need to make sure your graphics device supports your alphabet. 
Not all graphics devices have character support for all languages.
