Dear friends,
I am new to Rpy2 and I have the following problem.
I run the following example code from rpy2 documentation page
import rpy2.robjects as robjects
r = robjects.r
ctl =
robjects.FloatVector([4.17,5.58,5.18,6.11,4.50,4.61,5.17,4.53,5.33,5.14])
trt =
robjects.FloatVector([4.81,4.17,4.41,3.59,5.87,3.83,6.03,4.89,4.32,4.69])
group = r.gl(2, 10, 20, labels = ["Ctl","Trt"])
weight = ctl + trt
robjects.globalEnv["weight"] = weight
robjects.globalEnv["group"] = group
lm_D9 = r.lm("weight ~ group")
print(r.anova(lm_D9))
lm_D90 = r.lm("weight ~ group - 1")
*print(r.summary(lm_D90)*
everything runs fine till the penultimate line. On the last line I get the
following error
Error in chol2inv(Qr$qr[p1, p1, drop = FALSE]) :
lapack routines cannot be loaded
---------------------------------------------------------------------------
RRuntimeError Traceback (most recent call last)

C:\Python25\lib\site-packages\rpy2\robjects\__init__.pyc in __call__(self,
*args, **kwargs)
420 for k, v in kwargs.iteritems():
421 new_kwargs[k] = conversion.py2ri(v)
--> 422 res = super(RFunction, self).__call__(*new_args,
**new_kwargs)
423 res = conversion.ri2py(res)
424 return res
RRuntimeError: Error in chol2inv(Qr$qr[p1, p1, drop = FALSE]) :

I have R2.9.1, python2.5, and I have installed rpy2-2.0.6. My machine is
Window xp professional.
Any help will be highly appreciated.
Thank you.
