Re: [igraph] igraph 5.2 does not load in R 2.9.0, causes DLL error

[Gábor Csárdi]

Pierre, this might happen because R cannot find some DLL igraph.dll
depends on. In the past the most frequent reason for this was
installing R in a non-standard place. (I.e. not the default one
offered at installation.)

You can check that you indeed have igraph.dll at the right place and
then check which other dlls it depends on (e.g. by using dependency
walker), and that they are available to R as well.

My guess would be that you are missing iconv.dll, but that is just a guess.

Best,
Gabor
