[R] Problem in loading packages

[CALUM POLWART]

Is this an *Error* or a *Warning* that is produced.

I think it is "normal" that if you install a package and it was produced
for a different version of R you get a warning. Warnings are just that, not
errors.

I think your options to make that go away are:

Upgrade your R to 4.7
Install a specific version of the package (that's hard work) - it needs you
to know which package version was built from your current R
Suppress the warning (fixes nothing but you just don't see it) use
library(packagename, quietly= T)
