Error while working with png output on linux server
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. -- -----Original Message----- From: Thierry Onkelinx [mailto:thierry.onkelinx at inbo.be] Sent: Thursday, February 01, 2018 10:57 AM To: Sariya, Sanjeev <ss5505 at cumc.columbia.edu> Cc: Jeff Newmiller <jdnewmil at dcn.davis.ca.us>; r-help at r-project.org Subject: Re: [R] Error while working with png output on linux server Dear Sanjeev, It seems that you system neither supports X11 devices nor cairo devices.

Thanks for pointing to FAQ: I tried with cairo (shared in commands), unfortunately didn't work. -- Sanjeev Sariya -----Original Message----- From: Jeff Newmiller [mailto:jdnewmil at dcn.davis.ca.us] Sent: Thursday, February 01, 2018 10:12 AM To: r-help at r-project.org; Sariya, Sanjeev <ss5505 at cumc.columbia.edu>; r-help at r-project.org Subject: Re: [R] Error while working with png output on linux server FAQ 7.19?
