[R] plot and save as png

[Sarah Goslee]

Hi,

So when you run the code suggested:

png(filename = "fname.png", width = 900, height = 600, units = 'px')
layout(matrix(c(1,2,3,4), 4, 1, byrow = TRUE))
plot(sin, -pi, 10*pi)
plot(sin, -pi, 20*pi)
plot(sin, -pi, 30*pi)
plot(sin, -pi, 40*pi)
dev.off()

exactly like that, you do not get a file named fname.png in your
working directory?

Do you get an error message, or any other information from the R console?
