Sorry for the somewhat nondescript subject line, but I have two

1. What is a really good book on R for a nonprogrammer?
2. How do I open more than one R Graphics: Device 2(ACTIVE).

what is the R command that I can use to keep more than one plot open.
You can have more than one device available, but you need to address
them serially. Only one device can receive input at a time.
?Devices
?dev.set
I am
running a script from a book on Chemometrics that results in more
than one
graph during the execution, but it seems that R deletes each graph
when the
script calls for the next plot.
More likely you are seeing one graph displayed at a time on the screen
device. On my screen device the cmd-left-arrow will bring up prior
plots to a depth of 15 earlier results.
