Hi, is there alternative of lmer? I am not able to follow the video, lmer ,the package is not available for download for R version of 4.2, currently the latest in 2022 July

[@tonycarlsen1627]

If lme4 is not (currently) compatible with the latest version of R, you can install a previous version of R (e.g. 4.1.3) alongside your current one (just visit r-project.org), and then select the version of R you want to use in RStudio by going to Tools > Global Options > General > R Version, and selecting the "change" button. Hope that helps!
