[statnet_help] ERGM error

[Michał Bojanowski]

Dear Aditya,

Yeah, running old versions of the Statnet in an even older version of
R might be tricky... It's strange that suddenly stopped working
though, given that you managed the environment with 'renv'. You must
have updated something, right?

It was all already some time but I believe the issues might be related
to the rle functionality which for the moment was part of
statnet.common (or ergm) and was later externalized to a separate
package 'rle'.

I'm glad that all worked-out in the end.

Best,
Michal

Until recently, the code and the environment both worked just fine, I periodically re-ran the code on new data as updates were needed.
