QCA with R

Contact owners and managers

Welcome to this QCA group.

You can ask general questions about QCA, but more specifically the group is addressed to those using the QCA family of packages in R. Help us help you, by constructing an MRE (minimal reproducible example).

Sometimes, issues might appear for different operating systems, versions of R and versions of the installed packages. The following two R commands are useful:

R.version

sessionInfo()

Feel free to attach whatever you believe is relevant (.csv files, or R script files etc) all of your questions and answers will contribute to constructing an archive of potential topics that future users might be interested in.
