Hi, Please note the inconsistency between the behavior of rbind() and rbindlist() below.
m1 <- as.data.table(mtcars) m2 <- copy(m1) rbind(m1[, .SD[1], by=cyl], m2) # Gives warning and binds by name rbindlist(list(m1[, .SD[1], by=cyl], m2)) # no warning, and does NOT bind by name What do you think about making them have the same behavior and/or warning? Personally, I prefer the behavior of rbind(), and would prefer to see a warning if column names are ignored like they are with rbindlist().
