Hi Laura, have you tried the circstats toolbox for Matlab? I've used it for some basic circular statistics and it seems to work well. See https://se.mathworks.com/matlabcentral/fileexchange/10676-circular-statistics-toolbox-directional-statistics.

Giyeul Bae

R offers pretty good packages for circular statistics. You should try!

Laura Paletto

Thank you both, I will try matlab as I have no experience at all with R
