I have had an inquiry of this nature previously and sad to say was
completely unable to find a solution. I made numerous suggestions to
the inquirer, e.g.:
*looking for a plot.im() function masking the "real"
plot.im() function from spatstat
* cleaning out the global environment
(.RData) in case there were some "artefacts" hanging around that had an
impact on plot.im()
* completely *removing* .RData and starting again,...
It is very difficult to diagnose a problem like this remotely. If you
could find an R guru who was able to come and sit with you at your
computer it is ***just possible*** that they could track down what is
However it seems to me that the problem is due to some sort of
recalcitrance of the Windoze system and is thus probably insoluble.
I am cc-ing this to the person who made the previous inquiry. Pablo,
have there been any further developments since we last communicated
about this problem?
P. S. BTW Chris: Does plot.im() screw up with other images? E.g. what
happens if you do
