As a general note, if you want to do R-like manipulation of data in Python, you should look into 'numpy'. It's very standard, and provides an array type that works like R vectors, plus functions like 'log' and 'sum' that apply to all elements quickly. rpy2 also has some code to make it easy to inte

Thank you Laurent for your quick reply. The if k[i] == 0 in R is implement as being + p * (x == 0) which will add p if k[i]==0 or zero if not. I was trying to came up with a closer implementation but I cannot do sums or multiplications between Robjects is that right? 2012/2/23 Laurent Gautier

[Rpy] Faster way to perform computation of a R function

2012-02-23 Thread Bruno Santos
Hello everyone' I am trying to port an R function to estimate some parameters to the rpy2 but the performance in python is appaling. So I was wondering if there is a best way of doing this. What I have at the moment is: R code finbinom <-function(pars,x) { p<-pars[1] mu <- pars[2] size <- pars[3]
