Thank you. You example helped to FIX IT.
The problem is I guess somehow related to:
class(msexp$pepinfo$transition_group_id)
[1] "factor"
and the whole R type conversion , riddle.
For subscripts my intuition is: either require integer or do the
"cast" to the rowname type (character).
However, it seems that R somehow prefers to cast factors to integers...
it seems that %in% "casts" both vectors to the same type. But to which one?
Oh, I guess all this is neatly explained in the R standard ... but
websearching for it just returns:
standard deviation

how does a valid subscript (see first 2 lines) can produce an
