2. How did you solve the error?
install.packages("lme4", type = "source")
3. What are the possible causes of the error?
The problem is due to the lme4 package which we use to fit some statistical models in the groupComparison function. It has an issue with the older versions of the library Matrix that are not solved automatically on regular MSstats install.
