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<="" code="">

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)
