  • and when I try to install package "semTools" it says package ‘semTools’ is not available (for R version 3.6.1)... where can I download this version could not find a link – Melisa Sep 02 '22 at 20:36
  • Welcome to Stack Overflow! Can you please paste the error message in a **text format** rather than as an image/screenshot? – Ben Bolker Sep 02 '22 at 20:37
  • Your problem is that the most recent versions of most of these packages require more recent versions of R than you have (your version is quite old). Does [this answer](https://stackoverflow.com/questions/25721884/how-should-i-deal-with-package-xxx-is-not-available-for-r-version-x-y-z-wa/25721890#25721890) help? If you don't **need** this old a version of R for some reason, the quickest and easiest solution will be to download a recent version. – Ben Bolker Sep 02 '22 at 20:38
  • @BenBolker I can not find the most recent version download link for R MacOS could you maybe send it to me? And yes next time I will paste the error message as text sorry didn't know, I am new here – Melisa Sep 02 '22 at 20:41
  • You don't need to be sorry, that's why I told you. https://cran.r-project.org/bin/macosx/ – Ben Bolker Sep 02 '22 at 20:42
  • If your R is v. 3.6, you want package semTools v. 0.5.2. `remotes::install_version("semTools", "0.5.2")`. – Rui Barradas Sep 02 '22 at 20:48

You seem to have R version 3.6 (the version of RStudio is totally irrelevant here, RStudio is just a pretty window interface to R).

Version 3.6 of R is very old, and its not surprising that some packages no longer run on it. Upgrade your version of R to the latest (4-point-something) and you should be okay to install anything from CRAN.

Alternatively you may have to work hard to get that dependent package running on your old R version, for example finding an older repository or finding the source code and building for your version. This can be difficult.
