|Installation of SProCoP failed||lbergluecke||2020-05-11|
I get the following error message when trying to add SProCoP as an external tool:
Warning: unable to access index for repository http://cran.us.r-project.org/bin/windows/contrib/3.0
package 'qcc' is available as a source package but not as a binary
Any help or suggestions on how to fix this would be greatly appreciated.
