@ Ista: no, R still struggles with the output. Thanks anyway. :)  Is
there a way to merge multiple of these PNGs into a single PDF document
afterwards? I would like to refrain from bridging this gap with
additional software like f.i. Adobe Acrobat.

Dear list,

as described beforehand, i wanted to merge three single plots into one
JPEG-file. Since I use PNG now, code goes as follows:


png(...)

layout(...)

par(...)
plot(...)

par(...)
plot(...)

par(...)
plot(...)


which works out pretty well, but now a new problem occurred: R has
stopped to create new plots at all. Opening the PNG, the prior defined arrangement has been implemented but obviously no plots were compiled.
Plus, by commenting out the PNG-function (and even layout()), R
completely refuses to open up a plotting window (code runs all the way
without error messages, though).
Even entering the plotting command directly in the R shell leads to the
same result.

Any ideas?


Best

Alex
