The SSSDay took place on the 3-4th of Novembre 2022, hosted by the Conservatoire et Jardin Botaniques de Genève

salle de cours, Bot II (building number 3 on the map)

Thursday 03.11: Workshop on multivariate evolutionary models

Julien Cavel (Uni- Lyon I) demonstrated the R packages RPANDA (Phylogenetic ANalyses of DiversificAtion) and mvMORPH (morphometric data).

R packages to install: RPANDA, mvMORPH, Morpho, diagram.

Ideally, the version gitHub for mvMORPH is preferable. It can be installed from the package « devtools”, with a compiler already installed (e.g., gfortran ; Rtools for Windows ( or tools and gfortran for MacOS (
