RDataFrame *is* a Python class.
There are many ways to cast it into a different data structure, if you
wish to do so.
If going for a list of lists:
lolist = [[x for x in y] for y in dataf]
Note that going to a Python dictionary is not the most robust of the
ideas (there might be several elemen
Edit to the PS in my previous post:
I did have the time to make RVectors use R's "[".
use ".r[", e.g. dataf.r['Var1']

Thanks for your quick response, Laurent. I tried your suggestions and they
worked, but there's still one problem. One of my columns are strings, but when
I use the ".r[" operator, I get a list of numbers AND the list of strings. I
have no idea what the numbers represent. When I type data.r["V4"]
Factors are represented by integers numbers in R.
I think the numbers you got are the integer representation of factors
in your data frame.
Maybe if you convert factors for character you can solve the problem...
See the help for the factor() function.

I'm using version 2.0.0rc1.
I think that Marcos's suggestion (thanks!) that R is converting my
strings to factors is correct. I just need to figure out how to convert
them back to strings. Seems like my problem is more of an R issue than
an rpy2 issue. Still, I wonder how print() is able to pro
Hi,
I'm trying to use Rpy2 to save some plots that I've created using python2.5 +
rpy2 + R 2.8.0.
The plot displays in my X11 window fine, but I can't seem to save it.
If I do
r.png("filename.png", width=600, height=600)
r('dev.off()')
it creates a file called filename.png that's 0 bytes.

Update to the released 2.0.0 should probably be the first thing to consider.

Nevermind, I figured it out. The solution is to call r.bitmap *before* calling
the plot() command, and not after. whoops.

where are your plot functions? they should be between the device calls.
