Summary: heatmap_2
Initial Comment:
Dear rpyer,
when calling the function heatmap_2, there is a problem
because probably that the _ get systematically replace
by ., but in this case it shouldn't.
Got the error :
File "/usr/lib/python2.4/site-packages/rpy.py", line
290, in __getitem__
obj = self.__dict__[name] = self.__dict__.get(name,
self.get(name))
rpy.RException: Error in get(x, envir, mode, inherits)
: variable "heatmap.2" was not found
thank you

The problem is caused by forgetting to load the appropriate library via:
rpy.r.library('gplots')
before attempting to access the heatmap.2 function defined by said
library.

You will have to give us some more information.
What version of rpy are you using, what version of R.
It looks like you are usign Python 2.4 on Linux (or some
other unix like system - maybe Mac OS X perhaps?)
And most importantly, the python program that had this problem.
Have you read this page which might help?
