I have to correct my previous reply.
The changes you propose work The strange thing is that if I upload
the R-script to
produce the plot from file using
source("/Users/tomlenaerts/Programming/ObjC/Tools/AllEE/build/EEcont.R")
The script does not work.
When I copy-past the script myself into the R-window and execute things
work ok.
Any explanation for this?
