[R] vector in filename

[Simon Blomberg]

How about this:

x <- 1
y <- 1
mmax <- 10

my.files <- paste("foo", x:mmax, ".png", sep="")

for (i in my.files) {
	png(filename=i, pointsize=20, width=600, height=600, units="px",
	bg="#eaedd5")
	plot(x, y)
	dev.off()
	x <- x+1
	y <- y+1
}

Normally I would avoid for loops, but I think this application is a
legitimate use.

Cheers,

Simon.
