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)
