First, Laurent, I am giving rpy2 a try and REALLY like what I see so
far. It is very much more intuitive, both from the point-of-view of
an R programmer as well as for python programmers.
Data frames are very nice R data structures, so I would like to
capitalize on them and the changes included i

Unless you use a package like Rmpi. I have NO idea how that would
work with Rpy, but it is another possibility. Also, I think there has
been some work to vectorize the math libraries.

Hi, Ernesto.
You'll definitely need to learn R before using Rpy2 effectively. In
R, type help(fisher.test).

In this case, I'd suggest simply making a copy of the function
(cut-and-paste with appropriate modifications) into your Rpy session before
it is needed.

I'm totally new to rpy (and relatively to python). I would like to do the
rpy equivalent of the R code:
a <- data.frame(col1=rnorm(100),col2=rnorm(100), col3=1:100)
b <- a[a$col1>1,]
newdf <- a[b,]
More generally, one of the advantages of R is its powerful indexing, but I
haven't figured out ho

I haven't started playing much with S4 classes from RPy. I have used S4
classes a good bit in R, but wondered if anyone had some pointers on
constructing them and using them in RPy. In particular, there are many
packages in Bioconductor that heavily utilize S4 classes for data
manipulation, calc

Hi Sean,
RPy should be perfectly happy with S4 classes, so you should be able
to do what you want.

Just a quick question, I hope. I am trying to draw a heatmap of a numpy
array. Here is what I have tried and the output:
In [43]: x=numpy.array([1,2,3,4,5,6],dtype=numpy.float64)
In [44]: x.shape=2,3
In [45]: rpy.r.heatmap(x)
