Apply a single argument function to its argument.
# S4 method for rq_u_fn_w,data.frame ApplyTo(f, x, env = parent.frame()) # S4 method for rq_u_fn_w,UnaryFnList ApplyTo(f, x, env = parent.frame()) # S4 method for rq_u_fn_w,UnaryFn ApplyTo(f, x, env = parent.frame())
f | object of S4 class derived from UnaryFn. |
---|---|
x | argument. |
env | environment to work in. |
f(x) if x is not a UnaryFn else f composed with x.
