Return shapes with matching conditions, from the $fac. See examples and ?dplyr::filter.
Details
dplyr verbs are maintained. You should probbaly not filter on PCA objects. The latter are calculated using all individuals and filtering may lead to false conclusions. If you want to highlith some individuals, see examples in plot_PCA.
