Thank you very much.. It seems that the points problem is fairly easy
to solve, I just need to work on the mapping..

Thanks for the help on the translucent dots. What would be the best
method for creating a map of the facility? I looked into map* in the

Anders,
Does your data have missing values? It looks like they might. Look
at the 'use' parameter in cor. Also, is there a reason to use cor.test
instead of cor. Finally, if the expression values are not normal,
could you transform them first to make them more so--log2, for example?
And,

Hi there,
How can I plot a function in R which is defined by conditional
branches?, e.g.:
u(x) = 1, Edx2Ed (where Ed is a positive constant, say, 25);

So far I have had to use curve(..., add=TRUE) with two function define
by segments, i.e., two branches or
Are the results dramatically different?
The result would be expected to be somewhat different, as setting
importance=TRUE would make many calls to the random number generator (for
permuting OOB data in each variable), making all but the first tree in the
forest different than if importance=FALSE.

It looks like you have several non-printing characters.
nchar will give you the total number of characters in each character
string.
strsplit can break character strings into single characters, and
%in% can be used to classify them.

Yes, please provide an example of the data that can lead to the crash.
FWIW, the heatmap.2 function uses only standrd R calls and doesn't use any
external C code. (There isn't any C code in the entire library). So, the
bug is likely to stem from something in base R.
