oce (version 1.7-2)

ocePmatch: Partial matching of strings or numbers

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

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.

See Also

Since pmatch() is used for the actual matching, its documentation should be consulted.

Examples

# NOT RUN {
library(oce)
oce.pmatch(c("s", "at", "te"), list(salinity=1, temperature=3.1))
# }
