Extract convex hulls points of each type

[JohnSal1]

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)

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]), ]) Le lun. 28 oct. 2024 à 14:40, JohnSal1 ***@***.***> a écrit :
