Yes x = NA makes x logical but data.table is supposed to keep the type of the LHS when you do an update That's why you get the usual Message d'avis : In `[.data.table`(DT, , `:=`(a, 1.1)) : Coerced 'double' RHS to 'integer' to match the column's type; may have truncated precision. Either change the target column to 'double' first (by creating a new 'double' vector length 3 (nrows of entire table) and assign that; i.e. 'replace' column), or coerce RHS to 'integer' (e.g. 1L, NA_[real|integer]_, as.*, etc) to make your intent clear and for speed. Or, set the column type correctly up front when you create the table and stick to it, please.
So I think it should still be the case even for 1 row data.table -- View this message in context: http://r.789695.n4.nabble.com/Bug-filled-4878-tp4675263p4675268.html Sent from the datatable-help mailing list archive at Nabble.com. _______________________________________________ datatable-help mailing list [email protected] https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/datatable-help
