[kepler-users] Question about R workflow in Mac OS X

[Jorge A. Ahumada]

Hello,

I am interested in using Kepler for creating workflows with R. I have a MAC
10.4.6 PPC Dual G5 and downloaded the beta 6.1 of Kepler. When attempting to
run the linear regression workflow I get this error:

[R]> setwd('/Users/jorge')
[R]> jpeg(filename = '1150472825782.jpg',width = 480, height = 480,
pointsize = 12,quality = 75, bg = 'white')

Erro en X11(paste(\"jpeg::\", quality, \":\", filename, sep = \"\"), width,
: 
    no fue posible iniciar el dispositivo JPEG
Adem·s: Warning message:
no fue posible abrir la conecciÛn con el dispositivo X11 ''
EjecuciÛn interrumpida

X11 is open and I typed setenv DISPLAY localhost:0.0

Seems that the X11 command has the wrong syntax for Mac or Linux:
X11(paste(/"jpeg::/". Etc..)

How do I change it? Is this the problem..Any ideas?

Thanks,

Jorge
