[R] Error while working with png output on linux server

[Sariya, Sanjeev]

Thanks for your reply. I searched for the error on Google before resorting to the R forum (help group).
I tried Sys.env(...) too, but didn't resolve the error I get. Hence I am looking for solution.

Dear Sanjeev,

It seems that you system neither supports X11 devices nor cairo devices. See http://lmgtfy.com/?q=R+unable+to+open+connection+to+X11
for possible solutions.
