How can I upgrade to R 4.2 on Amazon Linux (Centos)

With ssh connection:

 R --version
R version 4.1.1 (2021-08-10) -- "Kick Things"

I want 4.2 to be able to use placeholder _ in native pipe.

Tried following instructions here:

export R_VERSION=4.2.1
curl -O https://cdn.rstudio.com/r/centos-8/pkgs/R-${R_VERSION}-1-1.x86_64.rpm
sudo yum install R-${R_VERSION}-1-1.x86_64.rpm

Looked like it installed:

curl -O https://cdn.rstudio.com/r/centos-8/pkgs/R-${R_VERSION}-1-1.x86_64.rpm

Complete!

But, when I run r version again:

R --version
R version 4.1.1 (2021-08-10) -- "Kick Things"

It's 4.1 and not 4.2 as desired.

How can I get up to version 4.2?
