[R] multiple plots problem

[Angel Lopez]

Depends on what you understand by _explicitly_ specify screen number:

par(bg = "white")           # default is likely to be transparent
screenlist<-split.screen(c(3,1))        # split display into three
i<-screenlist[1]

# Create a function to simulate the "tabbing"
nextplot<-function(i)
{
i<-i+1
if (i>screenlist[length(screenlist)]) i<-screenlist[1]
screen(i)
erase.screen(i)
return(i)
}

plot(1:10)
i<-nextplot(i)
plot(2:20)
i<-nextplot(i)
plot(3:30)
i<-nextplot(i)
plot(sin(40:400))
i<-nextplot(i)
plot(sin(4:40))
## Continue your plots
close.screen(all = TRUE)
