pmatchIC: pmatch ignoring case

In Ecfun: Functions for 'Ecdat'

pmatch ignoring case

Description

pmatch with an additional ignoreCase argument, returning a name not an index like pmatch (and returning a name if supplied a number, unlike pmatch, which coerces the input to numeric).

Usage

pmatchIC(x, table, nomatch = NA_integer_, 
  duplicates.ok = FALSE, 
  ignoreCase=TRUE)

Arguments

x	the values to be matched. If is.numeric(x), pmatch2 returns table[x]. This is different from pmatch, which matches as.character(x). Otherwise, if ignoreCase is TRUE, pmatchIC returns pmatch(tolower(x), tolower(table)).
table	the values to be matched against: converted to a character vector, per pmatch.
nomatch	the value to be returned at non-matching or multiply partially matching positions.
duplicates.ok	should elements be in table be used more than once? (See pmatch for an example.)
ignoreCase	logical: if TRUE and x is character, pmatchIC returns pmatch(tolower(x), tolower(table)).

Value

A character vector of matches.
