[statnet_help] ERGM error

[Khanna, Aditya]

Hello Statnet Dev Team and All,

I have some code for an ERGM that I developed in v 3.10.4 (and R 3.6.0). I
didn't upgrade it to the latest ERGM because it had a custom term and used
a very large underlying dataset. Until recently, the code and the
environment both worked just fine, I periodically re-ran the code on new
data as updates were needed.

Today I tried to run the code again, but it, and simpler versions of the
ERGM (i.e., a model as simple as just including the edges term), but all
failed. I then tried running a standard tutorial example, and it produces
the same error:


> data(florentine)

> summary(flomarriage ~ edges)

edges
   20

> ergm(formula = flomarriage ~ edges)

Error in rep(rle(v), r, scale = "run") : invalid 'times' argument

>


I have been managing the project using renv, so I don't know what
underlying thing might have changed.I would be grateful for any thoughts on
how to debug this. The sessionInfo() is included below.
