Hi,
Not sure if that's known problem, but with the following script
cut
import rpy2.robjects as ro
R = ro.

Hi,
Please consider the following:
from rpy2 import robjects as ro
df = ro.DataFrame({'a': ro.FloatVector((5,2,3)), 'b':
ro.StrVector(['x1-','y2-','z3-'])})
v = ((r.rx2('a')[0], r.rx2('b')[0]) for r in df.iter_row())
print(list(v))
The result is

Hi,
Let's say I create a vector of integers:
alist = list(range(10 ** 7))
avec = IntVector(alist)
How efficient is above? Do I have two copies of data or one?
If there is one copy of data, then what about data frames with
large vectors?
Best regards,
w

i have two x86 64-bit systems (PLD Linux and Fedora 14) on which

At the moment the segfau
While the os.popen does not cause my app to crash with UCS4, still
my application segfaults... just in different place. I will try to narrow it

Hi,
The setup.py on version_2.2.0 contains line
package_prefix = os.path.join('build', 'python3_rpy')
Shouldn't it be
package_prefix = os.path.join('build', 'rpy')
?

Hi,
Some time ago I have raised the bug
https://bitbucket.org/lgautier/rpy2/issue/65/segfault-with-unicode-characters-in-python
It is marked as fixed, but the problem still persists.
Tested with python 3.2.

Hello,
Please take a look at
>>> import rpy2.robjects as ro
>>> ro.FloatVector([ro.NA_Real, 1, 2, 3, ro.NA_Real])
[0.00, 1.00, 2.00, 3.00, 0.00]
Why NA_Real is converted to 0.0? Is it a bug or designed behaviour?
Best regards,
w
