Subject: cascade option for dev.new?
I frequently run scripts that generate multiple graphs. Unless you specify a specific window location, dev.new superimposes all new graphics windows exactly on top of each other. It would be nice to have a "cascade=TRUE" option in dev.new to prevent windows from being hidden. A hasty approximation to this is the following function:
# utility function to prevent overlapping plot windows
cascade <- function( k=dev.cur(),x0=300,y0=50,dx=30,dy=30){
dev.new( xpos=x0+k*dx, ypos=y0+k*dy);
invisible() }
x <- seq(-10,10,.1); y <- sin(x)
plot(x,y,type='l',main='first plot')
cascade()
plot(x,y,type='l',main='second plot')
