  post_process = I)

Arguments

collection_name	A name of collection.
connection	Connection object.
column_names	Names of specific columns.
post_process	Post process function called before query is run.

Examples

## Not run: 
# Set up a connection to DEFAULT_DB
cn <- connect()
tvs <- collection("tv_shows", cn)

isolate(tvs$collection)

# Using post_process you might use specific rethinkDB operations
# in rethinker query format before query is run (like filter, orderBy).
# E.g., to gather only tv shows with less than 100 episodes use:
tvs <- collection("tv_shows", cn,
            post_process = function(q) q$filter(function(x) x$bracket("episodes")$lt(100)))
