amcat.aggregate: Conduct an aggregate query on amcat
In amcat/amcat-r: R bindings for the AmCAT API

This function is similar to using the 'show table' function in AmCAT. It allows you to specify a number of queries and get the number of hits per search term, per period, etc.

amcat.aggregate(
  conn,
  queries,
  labels = queries,
  sets,
  axis1 = NULL,
  axis2 = NULL,
  ...
)

`conn`	the connection object from `amcat.connect`
`queries`	a vector of queries to run
`labels`	if given, labels corresponding to the queries
`sets`	one or more article set ids to query on
`axis1`	The first grouping (break/group by) variable, e.g. year, month, week, day, or medium
`axis2`	The second grouping (break/group by) variable, e.g. medium. Do not use a date interval here.
`...`	additional arguments to pass to the AmCAT API.
