Sorry, didn't notice the backticks - the second patched line should probably go like so:


-        ss[[2]] = parse(text="if (inherits(..1,'data.table')) return(`.rbind.data.table`(...))")[[1]]
+        ss[[2]] = parse(text="if (inherits(..1,'data.table')) return(data.table::.rbind.data.table(...))")[[1]]
