[R-pkg-devel] Packages required but not available

Reminder that you have to re-install any packages that your oncoPredict package depends on for the new R version 4.1.1.  Packages are downloaded/installed to a specific R version.  If you switch to another version, everything needs to be reinstalled.  I always get this error after upgrading or switching R versions.

 ?

If you?ve already reinstalled and are still getting the error, then maybe it is something with your NAMESPACE or DESCRIPTION file.  Like if you are using a package inside a function, but forget to add it to the DESCRIPTION.  Or you put it in the DESCRIPTION, but forget to add the @import roxygen directive above your function so that it gets into the NAMESPACE.  

 ?

Those are the situations that most commonly generate this error, from what I have seen.

Hello,

I received the following output from my package, oncoPredict.

However, I don't understand how to correct this error. I've tested the advice here:
https://stackoverflow.com/questions/14358814/error-in-r-cmd-check-packages-required-but-not-available
without success.

Any thoughts as to how this error can be fixed?
