Perhaps.
The code needed to find the maintainer is at the end of this scrape of a console "dialog" and scroll to the bottom if you want the proper address for reporting problems with package:ripa,
.... but _first_ you should be checking to see if you have all the system dependencies:
> require(ripa)
Loading required package: ripa
Loading required package: tcltk
Loading required package: parallel
Attaching package: ‘ripa’

# My guess is that you do not have all of the systemRequirements on this machine.
# Or if you do, then perhaps they are not in a directory in which the package expects to find them.
