Package: python-rpy2
Version: 2.2.6-1
Severity: normal
Dear Maintainer,
I'm not sure if this is a bug with rpy2 or r-cran-robustbase.
The following program will run successfully when n == 17, but breaks with n ==
18:
#!/usr/bin/python
from rpy2 import robjects as R
from rpy2.robjects.packages import importr
robustbase = importr("robustbase")
if __name__ == "__main__":
for n in (17, 18):
nums0 = list(range(n))
nums1 = list(range(n))
r_nums0 = R.FloatVector(nums0)
r_nums1 = R.FloatVector(nums1)
fit = robustbase.ltsReg(r_nums0, r_nums1)
The error given when n == 18 is:
Error in matrix(x, length(x), 1, dimnames = list(names(x),
deparse(substitute(x)))) :
length of 'dimnames' [2] not equal to array extent
Traceback (most recent call last):
File "./break_rpy2.py", line 17, in <module>
fit = robustbase.ltsReg(r_nums0, r_nums1)
File "/usr/lib/python2.7/dist-packages/rpy2/robjects/functions.py", line 82,
in __call__
return super(SignatureTranslatedFunction, self).__call__(*args, **kwargs)
File "/usr/lib/python2.7/dist-packages/rpy2/robjects/functions.py", line 34,
in __call__
res = super(Function, self).__call__(*new_args, **new_kwargs)
rpy2.rinterface.RRuntimeError: Error in matrix(x, length(x), 1, dimnames =
list(names(x), deparse(substitute(x)))) :
length of 'dimnames' [2] not equal to array extent
Thanks.
Andrew
