[R] screen resolution effects on graphics

[Gabor Grothendieck]

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
	}
}
