Trying to use the 'MAIT' package from Bioconductor.

It was OK last week but since, I have troubles with the "agricolae" package ...

This is how to install MAIT:


But then I have this error message:

I understood I had to update the package "agricolae", which I did but same issue, same error ...

A bit annoying as this is something that worked before - and apparently without the agricolae thing.

Thanks for your answers

Unfortunately the MAIT package is marked for deprecation and will no longer be supported by Bioconductor.  The package maintainers have been unresponsive and their package has been broken in both current release and devel versions of Bioconductor for quite some time.  You may reach out to the maintainers directly if you feel so inclined.
