Error in melt.default(profile) : 
  The melt generic in data.table has been passed a matrix and will attempt to redirect to the relevant reshape2 method; please note that reshape2 is superseded and is no longer actively developed, and this redirection is now deprecated. To continue using melt methods from reshape2 while both packages are attached, e.g. melt.list, you can prepend the namespace, i.e. reshape2::melt(profile). In the next version, this warning will become an error.

I submitted a PR to hilldiv anttonalberdi/hilldiv#4 but I get the feeling they may not submit an update to CRAN any time soon (last CRAN release 5 years ago).

I emailed [email protected] about wxgenR:
Hi David
I'm writing you because you are listed as the maintainer of the wxgenR package on CRAN.
There is a new issue when checking wxgenR using the new version of data.table that we plan to release in the next month or so: https://github.com/Rdatatable/data.table/issues/6670
I looked at the wxgenR code on CRAN, and I believe the fix should be changing melt(id = 1:6) to reshape2::melt(id = 1:6) on line 191 of Vignette_LowerSantaCruzRiverBasinAZ.Rmd
Can you please make that change, and submit an update of wxgenR to CRAN in the next week or so?
CRAN requires data.table to submit updates which do not break dependent packages like wxgenR.
Thanks
Toby
