[R] R newbie example code question

Sometimes I print out a package
and read about it and there
are sometimes nice examples
that I would like to run myself.
 
Is there a way to bring them
into R from the package or
are they only meant to be typed
in manually ? If manual is the
only way, that's fine. I was
just checking whether there was
a quicker way. Thanks.

Mark,
I am not user where you find your reading material, but if it is online, perhaps
you can copy and paste it into an R session.

I had the same issue many moons ago, and for the
same reasons! It was discussed in a fairly extended,
and interesting, thread from 24-27 May 2003 -- go to
the R-help archives for that month, by thread, and
find the thread

  [R] help output paged in separate window

The solution I finally opted for, and still use,
is based (in a Linux environment) on including
the following code in your .Rprofile file:

.xthelp <- function() {
    tdir <- tempdir()
    pgr <- paste(tdir, "/pgr", sep="")
    con <- file(pgr, "w")
    cat("#! /bin/bash\n", file=con)
    cat("export HLPFIL=`mktemp ", tdir, "/R_hlp.XXXXXX`\n",
         sep="", file=con)
    cat("cat > $HLPFIL\nxterm -e less $HLPFIL &\n", file=con)
    close(con)
    system(paste("chmod 755 ", pgr, sep=""))
    options(pager=pgr)
}
.xthelp()
rm(.xthelp)

(and it's also specific to the 'bash' shell because
of the "#! /bin/bash\n", but you should be able to
change this appropriately). The above was posted by
Roger Bivand on 27 May.

When you start an R session, this code is executed as
part of sourcing your .Rprofile, and it has the effect that
any output from R which would be paged is stored in a
temporary  file which is then read by 'less' in a
separate X window which is detached from your R session
(i.e. your command interface will not hang while it is
being displayed). You can close the X window displaying
the 'less' output by closing 'less' (e.g. type "q"),
or
you can leave it open and any new paged output will go
into a new window -- so you can for instance do

?glm
?family
?binomial

and you will have three mutually relevant help windows
open at once between which you can cross-reference.

As to extracting the code for examples, this is easy
in X windows since you just use your mouse: left-button
drag to hghlight a block of text, middle-button click
to paste the block into another window (of course the
mouse must be over the correct window!)

So you can use the mouse to copy code from the "help"
pages to the command window.

As I say, this is a Linux-oriented solution, and I don't
know what details would be required for anything similar
in a Windows environment.

It is also worth reading the various contributions to
the above thread, since several suggestions were made.

Hoping this helps,
Ted.

[R] R newbie example code question

Hello,
Why not just copy and paste the examples from the help pages? No need to
type anything.

However, if you'd like to run the entire help section for a function,
check out the example function, i.e.:> example(plot)
