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)
Please read An Introduction to R.
Please read ?Devices
Please read ?jpeg and see its examples!
jpeg() is not intended to save a plot, but to open a jpeg device you can
plot into and close it afterwards:
jpeg(file="test.jpeg", quality=90)
plot(1:10)
dev.off()
Please try it interaktively at first.
