Dear R-Users, I am reading the "An Introduction to R" manual and have come across data() function for loading data. I assume that R requires explicit loading of data objects to save memory. Then I'd expect there should be a function that can unload the objects once they are not needed anymore, what is this function? It would be helpful if ?data contained a reference to that function.

It's pretty rare that a data object loaded by data() would be large enough to be material in memory usage these days, but R was originally written for ca 2Mb systems. If it were, one might do better to use attach/detach (with a data file created with save). -- Brian D.

rm() will unload the data. See also attach() and detach() to load and unload .RData databases.
