class1 <- data[1==data$class,] gets you a subset of the data into a dedicated object, but if you want to handle arbitrarily large amounts of data or class values then the list output of split is really much better to stay with.
Also, "data" is a predefined function, so it is not a good idea to define objects with that name due to confusing code review. --------------------------------------------------------------------------- Jeff Newmiller The ..... .....
