Hello everyone,
I'm new to R and Rpy and in fact i'm still relatively new to Python. I keep
running into trouble and even though I searched the RPY-reference manual and
the R-reference manual i can't seem to find exactly why it is going wrong.
Also googling didn't provide any clues with regards to this error message,
so i thought i'd ask it here. Please excuse me for my ignorance if i'm doing
something really silly ;-).
---- insert code ----
from rpy import *
class Test:
def as_r(self):
return [[1,2,3,4,5],[2,3,4,5,1],[3,4,5,1,2],[4,5,1,2,3],[5,1,2,3,4]]
if __name__ == "__main__":
a=Test()
b=r.matrix(a)
r.kmeans(b, 2, 5, 1, "Forgy")
---- end code ----
Basically what i'm trying to do is to run the r.kmeans on a small set of
vectors.
According to the R-reference manual the imput should consist of a numeric
matrix
of data. Which i think i've created in the above piece of code. When i run
the code i get
the following output :
---- output ----
RHOME= C:\Program Files\R\R-2.4.0
RVERSION= 2.4.0
RVER= 2040
RUSER= C:\Documents and Settings\Ronald
Loading the R DLL C:\Program Files\R\R-2.4.0\bin\R.dll .. Done.
Loading Rpy version 2040 .. Done.
Creating the R object 'r' .. Done
Traceback (most recent call last):
File "rpy-test.py", line 10, in ?
r.kmeans(b, 2, 5, 1, "Forgy")
rpy.RException: Error in switch(nmeth, { : NA/NaN/Inf in foreign function
call (arg 1)
---- end output
Any clues would be highly appreciated.
