# constant: Get or set the constant term of a spray object

## Description

The constant term of a spray object is the coefficient corresponding to
an index of all zeros. These functions get or set the constant of a
spray object.

## Usage

constant(S,drop=FALSE)
constant(S) <- value

## Arguments

value

Numeric value to set the constant coefficient to

drop

Boolean, with default `FALSE`

meaning to return a
spray object and `TRUE`

meaning to return a numeric value

## Value

In function `constant()`

, return the coefficient, or a constant
multivariate polynomial, depending on the value of `drop`

.

## Examples

# NOT RUN {
S <- spray(partitions::blockparts(rep(2,4),3,TRUE))
constant(S)
constant(S) <- 33
S
# }
