Re: [igraph] Getting started in igraph in C

[Gábor Csárdi]

Hi Prithwiraj,

there is no straightforward way to convert R code into C AFAIK. R is a
much higher level language, with language constructs that are not easy
to express in C, so this is not a trivial thing.

I suggest that you identify the bottlenecks in your code, and then
rewrite only these in C, and keep the rest in R.
See the 'Writing R extensions' manual on the R homepage on how to call
C code from R.

Best,
Gabor
