I have tried to install Agricolae package and after several attempts, I succeed but it seems there is something wrong. When I call the package, I get the following message:
library(Agricola)
Error: package or namespace load failed for ‘agricolae’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):
there is no package called ‘sf’
How I fix this problem please. Thanks
It seems like you are having problems with your Matrix package, try uninstalling and reinstalling.
If you have recently updated to R >= 3.5 from R < 3.5 you are going to have a lot of this problems, if that is your case, I suggest you to reinstall all your packages.
