You need ls(all=TRUE) as some (12) are 'dot-names'. I just used foo <- ls("package:base", all =TRUE) pr <- foo[sapply(foo, function(x) is.primitive(get(x, "package:base")))]
and got 152. There is a description in the `Writing R Extensions' manual, but it is incomplete, and another classified list in tests/primitive-funs.R (also incomplete).
