Gabor:

I am afraid I am demonstrating my lack of computer savvy.

As you instructed, I downloaded the code, saved it as the file you
suggested, and executed this within R

as.numeric(gsub(".* ", "", grep("resolution",
 shell('cscript \\bin\\displayconfiguration.vbs', intern = TRUE),
value = TRUE)))

The DOS window opened, some magic occurred in the blink of an eye, and the
DOS window closed.  I haven't the foggiest idea what to do next since I

see no evidence of having done anything.

Thanks for your patience.

1.   Put the code from
 www.microsoft.com/technet/scriptcenter/resources/qanda/jul05/hey0721.mspx
into, say, \bin\displayconfiguration.vbs, and then from R do this:

as.numeric(gsub(".* ", "", grep("resolution",
 shell('cscript \\bin\\displayconfiguration.vbs', intern = TRUE),
value = TRUE)))


or we can translate that into R to eliminate the need for a vbs routine
and then run it directly from R (although we will still need the indicated
dll):

# must have GenericEnum.dll registered. That is, download and unzip:
#  http://sunsite.univie.ac.at/rcom/download/GenericEnum.zip
# and register it: regsvr32 GenericEnum.dll

library(RDCOMClient)
strComputer = "."
SWBemlocator <- COMCreate("WbemScripting.SWbemLocator")
objWMIService <- SWBemlocator$ConnectServer(strComputer,"\\root\\CIMV2")
colItems <- objWMIService$ExecQuery ("Select * from
Win32_DisplayConfiguration")

lEnum <- COMCreate("GenericEnum.AutomationEnum")
lEnum[["Collection"]] <- colItems

if (lEnum$SetFirst()) {
       repeat {
               cat(lEnum[["Item"]][["DeviceName"]], "\n")
               cat(lEnum[["Item"]][["BitsPerPel"]], "\n")
               cat(lEnum[["Item"]][["Pelswidth"]], "\n")
               cat(lEnum[["Item"]][["Pelsheight"]], "\n")
               if (!lEnum$SetNext()) break
       }
}

My apologies for my oversight.  I am using WindowsXP.  The code that
produces a nice-looking jpg (when viewed on my screen) produces cramped
graphics on a 800 X 600 screen.  I can change the spacings on the plot

remedy the situation for 800 X 600, but that looks awkward at 1280 X

Thanks

You forgot to mention your OS. This was asked before and if I recall
correctly the answer for Windows was no. An acceptable solution (imho)
is to edit the Rprofile.site files and add something like
 pngplotwidth <- 990 ; pngplotheight <- 700
 pdfplotwidth <- 14 ; pdfplotheight <- 10
Then, use these values in your functions. It's manual, but you only
need to do this once for each machine.

Greetings, R-Citizens:

I have the good fortune of working with a 19" 1280 X 1024
pixel monitor.  My
R-code produces nice-looking graphics on this machine but the
same code
results in crowded plots on an older machine with 800 X 600
resolution.  In
hindsight this seems obvious, but I didn't anticipate it.

My code will be used on machines with varying graphics (and memory)
capacity.  Is there a way I can check the native resolution
of the machine
so that I can make adjustments to my code for the possible
limitations of
the machine running it?

Thanks.
