[R] jpeg function problem with rterm.exe

[Audouy Jerome (ext_sub)]

Hello,

I'm starting using R and runned a little script. The generated graphic could be exported correctly with RGui.exe ("file -> save as -> jpeg -> etc.")

But if I try to run the same script with Rterm.exe and followed by:
jpeg(file="test.jpeg", quality=90)
The created jpeg file is completely white without any color, do you know why ?

Sum up of the script:
    library(DBI)
    library(RODBC)
    library(graphics)
    # my script process
    ...
    ...
    # save picture
    jpeg(file="test.jpeg", quality=90)


Thanks to help me.

Regards,
Jérôme.
