MATCH

Value Matching

Description

MATCH is a generic function for value matching.

Usage

MATCH(x, table, nomatch = NA, ...)
## S3 method for class 'times'
MATCH(x, table, nomatch = NA, units = "sec", eps = 1e-10, ...)

Arguments

`x`	an object.
`table`	the values to be matched against.
`nomatch`	the value to be returned in the case when no match is found. Note that it is coerced to `integer`.
`units`	See `trunc.times`.
`eps`	See `trunc.times`.
`...`	further arguments to be passed to methods.

Details

MATCH is a new generic function which aims at providing the functionality of the non-generic base function match for arbitrary objects. Currently, there is only a default method which simply calls match.

MATCH.times is used for chron objects. x will match any time in table less than units away.

Examples

MATCH(1:5, 2:3)
