Upcoming vctrs 0.7.0 release

We are working on the next vctrs release, targeted for Jan 15, and this package came up in our revdep analysis. I am unsure if this is a false positive or not. We saw `````` ## Newly broken * checking examples ... ERROR ``` ... > > # Run the simulation on the desired design > # We only generate 1 trial outcome here for illustration, for the actual study > # this should be increased of course, similarly for the McmcOptions - > # they also need to be increased. > mySims <- simulate( + design, + trueTox = trueTox, + trueBiomarker = trueBiomarker, + sigma2W = 0.01, + rho = 0, + nsim = 1, + parallel = FALSE, + seed = 3, + startingDose = 6, + mcmcOptions = McmcOptions( + burnin = 100, + step = 1, + samples = 300 + ) + ) Error in matrix(rnorm(n * ncol(sigma)), nrow = n, byrow = !pre0.9_9994) %*% : non-conformable arguments Calls: simulate ... .local -> get_result_list -> lapply -> FUN -> <Anonymous> Execution halted ``` `````` I am having trouble reproducing locally, as I'm having trouble getting rjags installed. Can you please test this package against the development version of vctrs? If there is an issue, can you please attempt a fix, or report back if you have any questions about a specific vctrs function? Thanks so much!
