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 ''
My system:
Linux AS 4.0 64-bit
PATH=/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/usr/X11
