Wordy title, simple example:
x = data.table(id = "aaa")
y = data.frame(id = "bbb")
class(y) = c("tbl_df", "tbl", "data.frame")
x[!y, on = "id"]
# Error in bmerge(i, x, leftcols, rightcols, roll, rollends, nomatch, mult, :
# Internal error in forderReuseSorting: reuseSorting set to TRUE but DT is not a data.table. Please report to the data.table issues tracker.No error on 1.15.4. No error if y is just plain data.frame.
It's the bmerge() code here that tries to call the new routine on the non-data.frame:
