[Rpy] rpy2.1 beta1+: problems with translated parameters
Hello,
I just updated to beta 1, and I found a problem with some of the translated
parameters in functions.
Test case:
from rpy2.robjects.packages import importr
base = importr("base")
sequence = list(base.seq(-10, 0, length_out=2))
len(sequence)
Result: 11 # wrong
parameter = {"length.out":2}
sequence = list(base.seq(-10, 0, **parameter))
len(sequence)
Result: 2 # Correct
Is this a bug? If so, where should I report it?

In a way. This is because of particularities with R.
"length_out" is only defined as a parameter in base.seq_int(), and
base.seq() is calling base.seq_int(). "length_out" is passed on to
seq_int() as part of the "..." (R's ellipsis), and therefore cannot be
guessed during the translation.
base.seq_int() will behave like you expect.
There is a way to manually force base.seq to translate "length_out" to
"length.out" (but that might break other things).

Re: [Rpy] 'show' not found
If anyone else encounters this problem, it appears to be something with R. After installing R from source (2.10.1) rather than the Ubuntu package (2.9.2), Rpy2 works as expected.

[Rpy] py2 and threading
Hi list, I was just looking back on some old posts and there is some mention of releasing Python's GIL being on the TODO list... Has this been done/explored any further? Regards, Carson -- Carson J.
