discrete function

Discrete Vector tools

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.

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.

Returns

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.
