It's trying to replace the length function inside the base namespace, which is not supported. You'd need to do this in two steps. "base_len<-" <- base::"length<-" base_len(x) <- 7 But maybe the way you suggest below is better... > I've tried to put some back quotes on the left side of the assignment in > different ways but was not successful.
