redis.zero(rc, key)
redis.inc(rc, key)
redis.dec(rc, key, N0 = FALSE)

`rc`	Redis connection as returned by `redis.connect`
`key`	key associated with the counter
`N0`	logical, if `TRUE` then counter will be reset to zero if decreasing it leads to negative number.

Counters are implemented directly in Redis and therefore do no behave like any other values set via redis.set since they are not serialized R objects. This is also why they have to be reset using redis.zero and cannot be set using redis.set.

Note that redis.dec with N0=TRUE is currently implemented such that the counter is first decremented and only if it leads to a negative value it is reset to zero.

integer, resulting counter value
