[igraph] R versus Python

[Thomas]

I am stuck in Circle 3 of The R Inferno (http://www.burns-stat.com/pages/Tutor/R_inferno.pdf 
) which means my programs are running **slow** because of failing to  
vectorize. Every program I write seems to have two or three nested for  
loops.

Anyway, I'm thinking of switching to Python and would be interested in  
hearing from anyone with an opinion on this. The alternative is to  
write vectorised functions in R and use those (there are no standard  
functions available for a lot of what I am doing - growing and  
manipulating graphs), but as far as I understand it, if I write those  
in R it won't have any impact on speed, in fact it will slow  
everything down even more. The only way to get this working faster  
would be to write the function in C. But then if I'm writing C, why  
not do it all in C? But then I want to use some igraph functions and I  
don't have C code for those etc etc. So I'm going around and around on  
this one.

Seems like Python might not object to nested for, plus it has the  
igraph routines available.

Anyone got any advice?

Thank you!
