1 month ago hi, sth like this should bring you on the way !
as_tibble(molars.l$x) %>% select(PC1:PC2) %>% mutate(group=molars.l$fac$type) %>% group_split(group) %>% map(~.x[chull(.x[, 1:2]), ])

Hi,
How can I extract the convex hulls points (or all points) of each type (e.g., LM1, LM2, UM1, UM2) and store them in a dataframe?
Script: library(Momocs)
molars.f <- efourier( molars) molars.p <- PCA( molars.f) molars.l <- LDA( molars.p,~type) plot_LDA( molars.l, chull = T, labelgroups = T,points = TRUE)
