Hi A.K

This is working
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()
but if I add this line
png(filename = "fname.png", width = 900, height = 600, units = 'px')
 no plot is generated.
where is the problem?.

thanks
veepsirtt
