Error reading package library(lessR)

[jksorens]

Hello,

I am trying to use lessR package to reverse code items, but receive an error upon reading the package. It installs fine but when I run library() it won't load. Can someone please help me figure out how to navigate this issue? This is vital for a class assignment.

It installs fine but when I run library() it won't load.

The output you are showing indicates that the package doesn't install fine, you are having issues with a package dependency, accordingly to this GitHub issue, it seems there is an issue with the CRAN version of Rcpp for MacOS systems, Can you try reinstalling it this way?

install.packages("Rcpp", repos="https://rcppcore.github.io/drat")
