Hey #rstats friends, if {quantreg} v5.87 is incompatible with R versions below 4.1¹, why is update.packages() happily trying – and failing without a meaningful error – to install it on R v4.0.5? I’m so confused. ¹: community.rstudio.com/t/gith…

The package does not have an explicit dependency declared as R (>= 4.1.0) so `update.packages()` does not know. So this may be a subtle bug in the `quantreg` package and we could let its maintainer (/cc @rkoenker) know. cloud.r-project.org/web/pack…

Thanks, @rkoenker. Upgrading R isn’t an option for me at the moment, but since I’m in no hurry to upgrade {quantreg} I’m happy to wait until CRAN gets the fixed version. :) And thanks for the package!
