typed-assign: Assign with type checking

In rtype: A strong type system for R

Description

Assign with type checking

Usage

atomic(x, ...) <- value

integer(x, ...) <- value

numeric(x, ...) <- value

double(x, ...) <- value

logical(x, ...) <- value

character(x, ...) <- value

raw(x, ...) <- value

complex(x, ...) <- value

matrix(x, ...) <- value

array(x, ...) <- value

list(x, ...) <- value

pairlist(x, ...) <- value

envir(x, ...) <- value

name(x, ...) <- value

symbol(x, ...) <- value

call(x, ...) <- value

factor(x, ...) <- value

fun(x, ...) <- value

expression(x, ...) <- value

language(x, ...) <- value

object(x, ...) <- value

table(x, ...) <- value

recursive(x, ...) <- value

vector(x, ...) <- value

data.frame(x, ...) <- value

null(x, ...) <- value

check(x, ...) <- value

Arguments

x	symbol
...	additional conditions taking the following forms: 1. fun = v, i.e. fun(x) must be equal v. 2. cond, i.e. cond(x) must be TRUE. 3. a function like function(x) mean(x) <= 5.0
value	value to be assigned

Examples

## Not run: 
x <- 10L
atomic(x) <- 20
numeric(x) <- 10
numeric(x, length = 10L) <- 1:10

cond1 <- function(x) mean(x) <= 5
numeric(x, cond1) <- 0:9

## End(Not run)
