[R] Saving R Graph to a file
Hi I am not sure why I can't get my plot saved to a file as .ps, I searched online and I found that I have to use something is called postscript,png or pdf function which I did but still not working. Actually what I have is a matrix with almost 300-400 columns. I need to create a histogram and boxplot for some columns as .ps file (with reasonable size if i can adjust that would be nice also) so I can import them in my latex code to display a good chart on my report. And I found out R display a certain limit of device. Can you please help me code this? This an example I create data(CO2) png(filename=C:/R/figure.png, height=295, width=300, bg=white) hist(CO2[,4]) device.off() pdf(filename=C:/R/figure.pdf, height=295, width=300, bg=white) hist(CO2[,4]) postscript(filename=C:/R/figure.pdf, height=295, width=300, bg=white) hist(CO2[,4]) Thanks -- View this message in context: http://r.789695.n4.nabble.com/Saving-R-Graph-to-a-file-tp4648369.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

That said, your example won't work properly because it is not properly coded. FI'm sure it gets tiresome being told to read the manual, but that is the way you learn R. For poscript output you need to read ?postscript() and follow the information there. There are important differences in detail between png(), pdf(), and postscript() that are critical. CAREFULLY read the help for postscript(), and also check into dev.off() use too. Your example doesn't restore things properly. If you do the above, you'll discover what is wrong with your example.

Some hints: For pdf(), height and width are in inches, not pixels. dev.off() is necessary after drawing the image for pdf(). The name for the file argument (file=c:/figure.xxx) is file not filename hist(CO2[,5]) is more interesting And yes, ?pdf ?postscript ?ping On 11/3/2012 11:16 PM, frespider wrote: Hi I am not sure why I can't get my plot saved to a file as .ps, I searched online and I found that I have to use something is called postscript,png or pdf function which I did but still not working.
