R help - Nov 2004 - R 2.0.1 jpeg() png() pdf() Mac OSX 10.3.5 - empty files being created

Hi everyone,

I've been opening up R 2.0.1 from the dock and then starting the Mac OSX
X11 server.

After that I call
>jpeg("test.jpg",plot(rnorm(10)))
and r pops up a quartz window with the appropriate graph in it and puts a
file called test.jpg into the HOME which is 0kb in size and is completely
empty.

There is no error message.

I've tried
>png("test.png", plot(rnorm(10)))
and
>pdf(plot(rnorm(10)))
with the same result.

I'm sure that I've got the appropriate libpng and jpeg libraries
installed
correctly from sourceforge as linked to by http://www.economia.unimi.it/R/

Thanks in advance
Yours

Jin Kee

Please do read the help page: the syntax is

jpeg("test.jpg")
plot(rnorm(10))
dev.off()

Also not as specified on their help pages.

You never plotted anything on the devices you opened, and you did not 
close them.
