Does this constitute a bug, or is there something I'm missing?
assigning sub-elements of a sparse Matrix via M[X]<-..., where X is a
2-column matrix, appears to drop user-assigned attributes. I dug around
in the R code for Matrix trying to find the relevant machinery but my
brain started to h

I assume you are concerned about this because the formula is defined
in one environment and the model fitting with weights occurs in a
separate function. If that is the case then the model fitting
function can create a new environment, a child of the formula's
environment, add the weights variable

But I did not. So I do
Thanks Ben for verifying the issue. It is always reassuring to hear
when others can reproduce the problem.
I wrote a small patch that fixes the issue

I believe there are two typos in ?file.path, section Value, 2nd paragraph.
1. There is a close parenthesis missing after Encoding, as it is
reading is a bit confusing, I had to backtrack and repeat.
