Hello,

My problem is quite simply, but I didn't find any solution...

I have a vector :

> truc

   longueur30 longueur40 longueur50 longueur60 longueur70 longueur80 longueur90
34 FALSE FALSE FALSE FALSE TRUE FALSE FALSE I would like to have the name of the column where there is "TRUE".

> colnames(truc)

[1] "longueur30" "longueur40" "longueur50" "longueur60" "longueur70" [6] "longueur80" "longueur90"

> truc[truc == T]
[1] TRUE
> colnames(truc[truc == T])
NULL How can I do it ?

Thank you for your help.
