To plot multiple PNG files
m <- matrix(runif(100*10), nrow=10)
png(filename = 'plot%03d.png')
for (i in 1:nrow(m)) {
plot(m[i,])
}
dev.off()
To plot multiple graphs as individual pages of a PDF file
m <- matrix(runif(100*10), nrow=10)
pdf(file = 'plot.pdf')
for (i in 1:nrow(m)) {
plot(m[i,])
}
dev.off()
