You can get all the plots into one file of any name using the pdf command

pdf(filename,onefile=TRUE)

place this before your loop and say this after your loop

dev.off()

to stop writing pictures to that pdf file.

In this way you can capture lots of images, but be careful.  They will be
really high quality, and therefore you might get a really large file size.

for more say this in R

? pdf
