XData cannot be a tibble

[FabianRoger]

If XDatais a tibble instead of a data.frame the function fails with

Error in switch(class(XData), list = { : EXPR must be a length 1 vector

the error message comes from the call to switch in switch(class(XData), ... as class(XData) gives [1] "tbl_df" "tbl" "data.frame" and thus a vector of length 3, if XData is a tibble.

repex:

Y = matrix(rpois(100, 2), nrow = 5)

XData = tibble(A = rnorm(20, 2,1),
               B = rnorm(20, 5, 2))

Hmsc(Y = Y, XData = XData, XFormula = ~A+B)

Just wanted to let you know as many people might use tibbles these days and the error message is pretty cryptic.

New version of Hmsc was released today on CRAN, and it fixes this error message. However, it may still fail as we are only prepared to handle data.frame or a list of data frames, and tibble seems to be neither. You may check with the latest version (3.0-4).

The fix looks obvious, though, and tibbles could be treated similarly as data frames as they inherit from data.frame.
