mapIds(..., multiVal="asNA") returns logical() instead of character() when all ids map multiply

[1] "logical"

Thanks @mtmorgan ! I will have a look into it.

Fixed in ensembldb 2.9.3

[1] "NULL"

Filter has a similar problem. I'd expect a character vector of length 0.

Thanks for reporting @Kayla-Morrell ! It's fixed in version 2.9.4

if (length(vals)) vals else character()

It seems like character(0) should be named so that things such as tibble::enframe() will work properly ('name' column is type character not integer).

> tibble::enframe(character(0))
# A tibble: 0 x 2
# … with 2 variables: name <int>, value <chr>
> tibble::enframe(setNames(nm = character(0)))
# A tibble: 0 x 2
# … with 2 variables: name <chr>, value <chr>

I made the changes - hope it works now. Thanks for reporting @Kayla-Morrell
