Scheme Features to R

Description Usage Arguments Details Value See Also

These functions are aliases for or thin wrappers around the functions in the base R funprog set. The aliases make the functions available under the names that are usual in Lisp/Scheme.

delete.matching(f, x)

reduce(f, x, init, right = FALSE, accumulate = FALSE)

map(f, ...)

keep.matching(f, x)

`f`	A function of the appropriate arity, as in `funprog`.
`x`	A vector.
`init`	As in `link{Reduce}`.
`right`	As in `link{Reduce}`.
`accumulate`	As in `link{Reduce}`.
`...`	As in `link{Map}`.

The following functions are aliases for functions from base:

map is base's Map;
reduce is base's Reduce;
keep.matching is base's Filter;

The delete.matching function does the opposite of keep.matching and returns only elements of x for which f does not return a logically true value.

delete.matching returns the elements of x for which f is not logically true.

The functional-programming functions in base, especially Filter, under funprog.
