Hi all

When I run the Check-R protocol, I am getting the following errors.:

Error in read.table(file = file, header = header, sep = sep, quote = quote,  :

  no lines available in input

Error in X11(paste("png::", filename, sep = ""), width, height, pointsize,  :

  unable to start device PNG

Calls: png

In addition: Warning message:

In png(filename = "/home/accelrys/Accelrys/PPS85/web/jobs/hp/{ppcE23C7-1754-E46E-6BBB-4DC43C6F0E6C}/temp/Rplot9927560%03d.png",  :

  unable to open connection to X11 display ''

Execution halted

How do i get rid of it
