Dear all
Is there any simple way checking whether after calling pdf device something was
plotted into it?
In interactive session I used
if (dev.cur()==1) plot(ecdf(rnorm(100))) else plot(ecdf(rnorm(100)), add=T,
col=i)
which enabled me to test if plot is open
But when I want to call eg. pdf("test.pdf") before cycle
dev.cur()==1 is FALSE even when no plot is drawn and plot.new error comes.
> pdf("test.pdf")
if (dev.cur()==1) plot(ecdf(rnorm(100))) else plot(ecdf(rnorm(100)), add=T,
col=i)
Error in segments(ti.l, y, ti.r, y, col = col.hor, lty = lty, lwd = lwd, :
plot.new has not been called yet
Best regards
Petr
