Re: [R-pkg-devel] [External] Formula modeling

There's a Formula package on CRAN that's designed for this use case. lme4 and nlme don't use it, but implement their own formula manipulation machinery. (The cleanest version of this machinery is actually in glmmTMB at https://

I don't work with models like this, but I would find it more natural to express the multiple formulas in a list: list(d ~ p + x + y, s ~ p + w + y, p ~ z + y) I'd really have no idea how either of the proposals below should be parsed. Of course, if people working with models like this are us

Re: [R-pkg-devel] [External] Formula modeling

I am responding to a subset of what you asked. There are packages which use multiple formulas in their argument sequence. What you have as a single formula with | as a separator q | p | subject | time | rho ~ p + x + y | p + w + y | z + y I think would be better as a comma-separated list of fo
