Find the members in a list matching a member expression

Description

Find the members in a list matching a member expression

Usage

MatchListMembers(object, member, enclos = "?", q = "'", ...)

Arguments

object	a list containing named elements.
member	a member expression. Member expressions are character strings denoting named elements in a list object (see examples).
enclos	a character string containing the special symbol '?'. This symbol is to be replaced by matching expressions. The result of this substitution can be anything but, usually would be a valid R expression. Default: "?".
q	a quote symbol, Default: "'".
...	additional arguments passed to grep. For example, these could be ignore.case=TRUE or perl=TRUE.

Value

a named character vector, with names corresponding to the matched member quoted expressions (using the argument q as a quote symbol), and values corresponding to the 'enclos-ed' expressions after substituting the '?'.
