r - Multiple Plots in one pdf file -


i try this:

for(i in 1:10) {   pdf("filename.pdf",onefile=true)   plot(...) } dev.off()

and

for(i in 1:10) {   pdf("filename.pdf",onefile=true)   plot(...)   dev.off() }

but work. how correct code? need every plot new page.

you opening new pdf in loop. try opening pdf beforehand , closing after loop. 

pdf("filename.pdf",onefile=true)     for(i in 1:10) {   plot(...) } dev.off()
