[Michael Kubovy]

Dear R-helpers,

In JGR:
jpeg()
Error in X11(paste("jpeg::", quality, ":", filename, sep = ""),  
width,  :
	unable to start device JPEG
In addition: Warning message:
unable to open connection to X11 display ''

Version 2.3.1 (2006-06-01)
powerpc-apple-darwin8.6.0

attached base packages:
[1] "grid"      "datasets"  "methods"   "stats"     "graphics"   
"grDevices" "utils"     "base"

other attached packages:
     R2HTML      Hmisc    effects    foreign    lattice        
MASS        JGR     JavaGD      rJava
     "1.57"   "3.0-12"    "1.0-8"   "0.8-15"  "0.13-10" "7.2-27.1"     
"1.4-2"    "0.3-3"    "0.4-3"


But in the R Os X GUI, the command works, and produces Rplot001.jpeg
