[R] tyring to save plots using windoze 7 and cygwin

[Joshua Wiley]

Hi Mike,

I am using Windows 7 x64 with
> sessionInfo()
R version 2.11.1 (2010-05-31)
x86_64-pc-mingw32

First off the Rplots.pdf is created by your call to plot().  Just like
the console output is diverted when running scripts, it does not make
sense to send the graphics to the usual windows device.  This fact
also wreaks a bit of havoc on functions that you might normally use in
an interactive session.  I think the easiest thing to do is just pick
the format you want from the get go.  For instance, in your script
file:

######################################
# Initialize pdf (or whatever) device
pdf("myfile.pdf")
# plot your graph
plot(xyz, main="imp rate", xlab="Time(GMT)",ylab="imp/minute")
# add the grid lines
grid()
# shut the device down
dev.off()
########################################

You would use a similar process for postscript(), png(), etc.  What
version of R are you using?  I do not have the save.plot() function
(at least in the packages that load by default).  You can learn more
by poking around the help pages ?dev.copy ?Devices ?windows

HTH,

Josh
