Hi, I have a run of 5 graphs that I want to place them under the same page. Everything works fine to place them in a pdf file , or eps file, but when it comes to have a high quality of 300 dpi these graphs are not good. For example I open the eps file with Adobe Illustrator (AI) and it shows that it is a 72dpi graph. If I start with a 72dpi graph AI cannot improve this to 300 dpi. Q: HOW CAN A GRAPH IN R DIRECTLY SAVED AS 300dpi? What options do I need to add to the postscript function to have a 1 page graph that has these 5 plots and is a 300 dpi graph? Thank you in advance, Aldi Here is what I am using right now: > postscript(file='./plotST.eps',paper='special',width=10,height=10,horizontal=FALSE) > par(mfrow=c(5 ,1)) > plot(sortord , X1 , cex=0.5 ,pch=21 , ylim=c(1.000002 , 8.08771 ), xlab='ST: 1-5 position (unit)',ylab='ylabel',font.lab = 1, cex.lab = 1,cex.main=0.5 +0.4, col=chrom ) > text(midpointsbyc+minadj+5,0-5,chnum ,cex=0.5 +0.2 ,col=chnum+1 ) > abline(h = -1*log10(9.7e-08 ), lty = 2,col = 'gray' ) > # Draw the legend > legend('topright',legend=c('X1')) > plot(sortord , X2.... .... > # Put a box around the plot > box(lwd = 1) > dev.off() --

So your problem is not with the R-generated eps but somewhere downstream from that. Any postprocessing, conversion or editing? cu Philipp -- Dr. Philipp Pagel Lehrstuhl f?r Genomorientierte Bioinformatik Technische Universit?t M?nchen Wissenschaftszentrum Weihenstephan Maximus-von-Imhof-Forum 3 85354 Freising, Germany http://webclu.bio.wzw.tum.de/~pagel/
