I get this error trying to run the meta for package, although I checked the path and version and there was no problem

RInterpreterError: Failed to parse and evaluate line '…'.
R error message: 'Error in library(Matrix) : there is no package called ‘Matrix’'

Check：R version 4.2.3 (2023-03-15) -- "Shortstop Beagle"

find.package("Matrix")

I want to know what went wrong. Any ideas? Thanks!

It looks like you need to install the {Matrix} package. Try

install.packages("Matrix")

What is the command that outputs this error?
