@ClaireSnibbe

there is no package called ‘R6’

You are missing a package dependency, you have to install it first.

install.packages("R6")

Thank you - I actually did that before you replied. Now I have a problem with mice checking for multicollinearity and removing all the predictors. My collaborator at the University of Liverpool is not experiencing this with R version 4.0.2. My R was a later version, so I backgraded it to be version 4.0.2 but mice must be 4.0.5? I do not want mice to check for multicollinearity - is it possible a previous version of mice was not doing this check? My goal is to reproduce the results in a published paper as part of my Master's Thesis. And R's mice package is what was used in this paper, as oppose to Python's implementation of mice via statsmodel.imputation.mice.

This is a very different question, we like to keep things tidy around here so please ask it on a new topic providing a proper REPRoducible EXample (reprex) illustrating your issue.
