Hello

when I try to install the R package r-bdp2 with the R-base version 4.3.1, I receive the following traceback.

Could not solve for environment specs
The following packages are incompatible
├─ r-base 4.3.1**  is requested and can be installed;
└─ r-bdp2 0.1.3**  is not installable because there are no viable options
   ├─ r-bdp2 0.1.3 would require
   │  └─ r-base >=3.6,<3.7.0a0 , which conflicts with any installable versions previously reported;
   └─ r-bdp2 0.1.3 would require
      └─ r-base >=4.2,<4.3.0a0 , which conflicts with any installable versions previously reported.

I also contacted the package maintainers, they said they did not upload it to anaconda (only to CRAN).

Where do these package requirements come from and how can I make them work for the most recent R version (or in this case 4.3.1)?

Thank you very much for the assistance.
