Hi all,
When I ran a script containing the following codes:
png(paste(savepath,"a_rnaplot.png",sep = ""),width =
fwidth, height = fheight,pointsize = fpointsize);
data_deg <- AffyRNAdeg(data_cel)
plotAffyRNAdeg(data_deg,col=cols,lty=1,lwd = "2")
#a <- par("fin")
legend("bottomright",sampleNames(data_cel),col=cols,lty=1)
RNAdegSlope = cbind("Sample Names" = data_deg$sample.names,
"RNA Deg Slope" = data_deg$slope)
write.csv(RNAdegSlope, file = paste(savepath,"RNAdegSlope.csv",sep
= ""))
dev.off()
I got this error message:
Error in X11(paste("png::", filename, sep = ""), width,
height, pointsize, :
unable to start device PNG
In addition: Warning message:
unable to open connection to X11 display ''

I managed to delete the original post about this and will no doubt mess up
threading of responses. The post is shown below.
This looks like a problem I saw just a couple of days ago. I noticed that
you used a path variable in determining the file location and name. If
something is wrong with your path (e.g. the directories it specifies don't
exist) I think you will get this error.
Check your path to make sure it is ok.
