I'd like to use package CentiServer in R. However, I'm getting the same error with different R versions (3.3.3 and 3.1.1):
Warning: unable to access index for repository https://cloud.r-project.org/bin/windows/contrib/3.1 Warning message: package ‘CentiServer’ is not available (for R version 3.1.1)
This post is a great source, still, these steps couldn't help me to find a solution: How should I deal with "package 'xxx' is not available (for R version x.y.z)" warning?
Since I cannot install the package, I started to think about that it could be easier to just find the source codes of some useful functions in the .zip file. Where can I find those in the .zip file?
Thank you in advance.
