Not available via cran

[erfanv]

This package appears to be no longer available through the [R] CRAN. When trying to install, I get the following error:
Warning message:
package ‘cheddar’ is not available (for R version 3.6.2)

Apparently has also been removed from CRAN: https://cran.r-project.org/web/packages/cheddar/index.html

Would be great to still have a way to use this package, or even know at least which version of [R] it is compatible with.

Thank you!
