redisLIndex: Retrieve a value from a Redis 'list.'

In rredis: "Redis" Key/Value Database Client

Usage

redisLIndex(key, index, ...)

Arguments

key	The key (whose value is of the type 'list').
index	The list index to retrieve.
...	Optional additional arguments. Specify raw=TRUE to skip de-serialization of the data.

List indices begin at 0. Negative indexes are supported, for example -1 is the last element, -2 the penultimate and so on. If the value stored at key is not of the 'list' type an error is returned. If the index is out of range an empty string is returned.
