Partial matching of strings or numbers

Share:

Description

An extended version of pmatch that allows x to be numeric or string-based. As with pmatch, partial string matches are handled. This is a wrapper that is useful mainly for which arguments to plotting functions.

Usage

1
ocePmatch(x, table, nomatch = NA_integer_, duplicates.ok = FALSE)

Arguments

x

a code, or vector of codes. This may be numeric, in which case it is simply returned without further analysis of the other arguments, or it may be string-based, in which case pmatch is used to find numeric matches.

table

a list that maps strings to numbers; pmatch is used on names(table). If the name contains characters that are normally not permitted in a variable name, use quotes, e.g. list(salinity=1, temperature=2, "salinity+temperature"=3).

nomatch

value to be returned for cases of no match (passed to pmatch.

duplicates.ok

code for the handling of duplicates (passed to pmatch).

Value

A number, or vector of numbers, corresponding to the matches. Non-matches are indicated with NA values, or whatever value is given by the NA argument.
