Error in reg(ChickWeight, weight ~ Time + Diet, vcov_cluster = ~ Chick, vcov_type = "boot")

As you mentioned in the README, this regression does not work and this is the error message:

object of type 'closure' is not subsettable

I believe it's probably from line 52:

data = data[sample(seq_len(nrow(data)), nrow(data), TRUE), ], ...))

data is a function to load example datasets, and I think that this is where it goes wrong (you're trying to subset a function). I tried replacing data with dataset and when running the unit tests this is what I get:

==> devtools::test()

I don't know if this helps, but thought I'd mention.

Thanks. I think it might be an issue in how arguments are evaluated by {sandwich}. Will have to investigate more.
