Richard, I have not been using rpy all that long, but it seems powerful to me.
I suggest first reading rpy documentation and especially the sections on
notation of underscores.
Second, when I use scripts I generally create a file/script and then call the
script from python/rpy. There are probably several ways to do this, but here is
a general outline to get you started:
from rpy import *
regression_Rcode_File = "your_path_and_filename_here"
#Source the script
r.source(regression_Rcode_File)
#Assign a name to the function in script and it can then be called as such
#It is necessary to define the data in python and then pass via rpy as well
fitted_model = r.lm(x, y, wgt)
A good example that I referred to when I first started learning (This also
includes an example for plotting):

I hope this is helpful,
mike

Subject: Re: [Rpy] Fwd: R while loop
Hello Sean,
The code that i was using was simply pasting the same code in python.
r("
i<-1") # i should use the attach statement i think
r("while (i <= length(groups) ) {")
r("png(file=sprintf('MAplot%03d.png', i), width=600, height=600)")
r("MAplot(rawAffyData, pairs=TRUE, plot.method='smoothScatter'
which=groups[[i]])")
r("dev.off
()")
r("i<-i+1 }")
But i expect that using rpy in such a way is completely wrong. I'm just testing
what can be done by rpy
Currently they have rserve running on a server that connects several app's to
R. The only problem is that i couldn't
find a interface between python and rserve.
Besides the lack of the interface, rserve caused a lot of maintenance problems
so i suggested to look further into rpy as
interface between the apps and R.
I can't give you the exact error because i'm not in the office now but i think
it was something about ''unsubscribe error'' and it gave the first line till {
between brackets.
Hope this helps,
Thanks
Richard
ps: if you need the exact error i will post it tomorrow ( for me :) )

Hello Rpy users,
Probably a very simple question but i couldn't find the answer in the
documentation.
i have a r script which uses a while loop, how should i execute this in rpy ?
the script looks like:
i<-1
while (i <= length(groups) ) {
png(file=sprintf('MAplot%03d.png', i), width=600, height=600)
MAplot(rawAffyData, pairs=TRUE,
plot.method='smoothScatter' which=groups[[i]])
dev.off()
i<-i+1 }
if i normally run this in a r terminal everything will go fine but
running it from rpy line by line will give a error.
Hi, Richard.
What error are you getting? And what is the python code that you are using?
Sean
