How to Fix PKI package Installation Issues in R

I'm using RStudio server in Redhat linux. When I installed PKI package, I got error message like shown below. There is something wrong with my openssl library in OS.

It's very simple to fix this problem.
Just install the openssl library.

sudo yum install openssl-devel

Then everything is OK.


Error message:
