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

### 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

### Details

`as.discrete` converts a vector into a discrete vector.

`discrete` creates a discrete vector from provided values.

`is.discrete` tests to see if the vector is a discrete vector.

### 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`.

### Examples

``````a <- discrete(1:25)
a

is.discrete(a)

b <- as.discrete(2:4)
b
``````
