R help - May 2006 - problem with pdf() R 2.2.1, os 10.4.6

Hi,
I'm trying to write a histogram to a pdf

pdf()
plot<-hist(c, xlim=c( 0.69, 0.84), ylim=c(0,100))

when I try to open the pdf I can't open it, there is always some 
error . Is there something I should add to make it run under this 
operation system? I had problems upgrading to 2.3 (problem 
downloading packages) so I'm not sure an upgrade will work out with 
me. I just want a publication quality histogram...

thank you,
betty

Betty,

You need to explicitly close the pdf device with:

  dev.off()

once the plotting related code has completed. See the example in ?pdf
for more information.

Otherwise, the result of hist() is not flushed to the disk file and the
file then properly closed.

HTH,
