Dear Raquel Mendes,
If I got you properly you need a separate varible of the same length as a list
you got by reading a tps file into R. This variable would code a group for your
specimens. You could simply type it by yourself, like code <- c(1,2,1,2,3),
assuming that 1,2,3 are the groups. But if a list is long, one may generate it
from IDs.
