Dear R-experts, I hope that question will not be too redundant (sorry if it is) but i don't seem able to find the answer i need in the archives... I try to create a file which would have 1.several pages and 2.several plots by page. I know how to make a pdf file this way, but my problem is that the pdf size gets way too big and cannot be open. So my question is: - is there a way to diminish the pdf size/quality? - does any other file format exists that would be of smaller quality but still be able to print plots on several pages for the same file? Thank you for your help! Sarah [[alternative HTML version deleted]]

[R] Plots - several pages per pdf - quality/size issue

Some possibilities: 1. Use, e.g., Picasa to browse your plot files. 2. Create a simple webpage containing each image # R code png("test%d.png") print(p1) dev.off() # Web page code <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> </head> <body> <img alt="first plot" src="test1.png" /> <img alt="second plot" src="test2.png" /> <img alt="third plot" src="test3.png" /> </body> # File sizes 3*13kb + 1kb Open and save this file in a word processor of your choice, and you can probably drop the file size even further.
