Cannot open any libraries

[Shoichi]

Hello,

I have trouble to open libraries. I show an example (tidyverse).
I cannot open any libraries along with tidyverse.
I tried to renew the rstudio, but it did not work.
When I used rstudio two weeks ago, I had no problems like this.
If you have a kind suggestion, please help me.
Thank you for your cooperation in advance.

This post suggests updating from R 4.0 to R 4.0.2 - https://discourse.mc-stan.org/t/after-installing-brms-rstan-or-brms-will-not-load/16798/4

Are you able to do that?

I downloaded R 4.0.2 (for MAC) from
https://cran.r-project.org/bin/macosx/
and installed.
It works properly now.
Thank you, mrmallironmaker!

I thought R 4.0. was also updated to R 4.0.2 because Rstudio has been already updated to the latest version. I understand the version of R is different from the version of Rstudio. Updating Rstudio does not mean the updating R's version.
Thank you again.
