zap: Remove minuscule coefficients

Description

A convenience function for setting polynomial coefficients likely to be entirely round-off error to zero. The decision is relegated to the function base::zapsmall, to which this is a front-end.

Usage

zap(x, digits = getOption("digits"))
# S3 method for default
zap(x, digits = getOption("digits"))
# S3 method for polynom
zap(x, digits = getOption("digits"))
# S3 method for polylist
zap(x, digits = getOption("digits"))

Arguments

x

A polynomial or polylist object

digits

As for base::zapsmall

...

Passed on to base::zapsmall

Value

A polynomial or polylist object with minuscule coefficients set to zero.

Examples

# NOT RUN {
(P <- poly_orth(-2:2, norm = FALSE))
zap(P)
# }
