Hi! I am facing an issue while trying to calculate repertoire overlap, Morisita index in particular. Not sure whether this is truly a typo/a bug and not myself doing something wrong.

Here it is, using the example repseq dataset from immunarch:

immunarch::repOverlap(immdata$data, 'morisita', 'nuc', .verbose = T) |==
| 1%Error in tbl_dt(.x) : could not find function "tbl_dt"

Can it be a typo somewhere in the function? Or am I missing a package?

Thank you for help!

Hi @AnnaVyborova, you need to upgrade to a newer immunarch release to solve it :) most recommended is, generally, the latest (or even the developer version).
