discrete: Discrete Vector tools

Description

discrete creates a discrete vector which is distinct from a continuous vector, or a factor/ordered vector. The other function are tools for manipulating descrete vectors.

Usage

as.discrete(x, ...)
# S3 method for default
as.discrete(x, ...)
discrete(x, levels = sort(unique.default(x), na.last = TRUE), exclude = NA)
# S3 method for discrete
[(x, ...) <- value
# S3 method for discrete
[(x, ..., drop = FALSE)
# S3 method for discrete
[[(x, i)
is.discrete(x)
# S3 method for discrete
is.na(x) <- value
# S3 method for discrete
length(x) <- value

Value

as.discrete, discrete returns a vector of

discrete type.

is.discrete returan logical TRUE if the vector is of class discrete other wise it returns FALSE.

Arguments

x

a vector

drop

Should unused levels be dropped.

exclude

logical: should NA be excluded.

i

indexing vector

levels

charater: list of individual level values

value

index of elements to set to NA

...

arguments to be passed to other functions
