#' Return Competitions data
#'
#' \code{listCompetitions} simply lists all competitions associated with the
#' selected parameters (e.g. soccer competitions with markets closing in the
#' next 24 hours). This data is useful for finding specific event identifiers
#' (e.g. EPL = 31, Champions League = 228), which are then usually passed to
#' further functions. By default, \code{listCompetitions} returns are limited to
#' the forthcoming 24-hour period. However, this can be changed by user
#' specified date/time stamps.
#'
#' @seealso \code{\link{loginBF}}, which must be executed first.
#'
#' @param eventTypeIds vector <String>. Restrict competitions by event type
#' associated with the market. (e.g., Football = 1, Horse Racing = 7, etc).
#' Accepts multiple IDs (See examples). IDs can be obtained via
#' \code{\link{listEventTypes}}. Required. No default.
#'
#' @param marketTypeCodes vector <String>. Restrict to competitions that match
#' the type of the market (i.e. MATCH_ODDS, HALF_TIME_SCORE). You should use
#' this instead of relying on the market name as the market type codes are the
#' same in all locales. Accepts multiple market type codes (See examples).
#' Market type codes can be obtained via \code{\link{listMarketTypes}}.
#' Optional. Default is NULL.
#'
#' @param fromDate The start date from which to return matching competitions.
#' Format is \%Y-\%m-\%dT\%TZ, tz = "UTC". Times must be submitted in UTC as this is what is used
#' by Betfair. Optional. If not defined, it defaults to
#' current system date and time minus 2 hours (to allow searching of all
#' in-play football matches).
#'
#' @param toDate The end date to stop returning matching competitions. Format is
#' \%Y-\%m-\%dT\%TZ, tz = "UTC". Times must be submitted in UTC as this is what is used
#' by Betfair. Optional. If not defined defaults to the current system
#' date and time plus 24 hours.
#'
#' @param eventIds vector <String>. Restrict to competitions that are associated
#' with the specified eventIDs (e.g. "27675602"). Optional. Default is NULL.
#'
#' @param competitionIds vector <String>. Restrict to competitions that are
#' associated with the specified competition IDs (e.g. EPL = "31", La Liga =
#' "117"). Competition IDs can obtained via \code{\link{listCompetitions}}.
#' Optional. Default is NULL.
#'
#' @param marketIds vector <String>. Restrict to competitions that are
#' associated with the specified marketIDs (e.g. "1.122958246"). Optional.
#' Default is NULL.
#'
#' @param marketCountries vector <String>. Restrict to competitions that are in
#' the specified country or countries. Accepts multiple country codes. Codes
#' can be obtained via \code{\link{listCountries}}. Optional. Default is NULL.
#'
#' @param venues vector <String>. Restrict competitions by the venue associated
#' with the market. This functionality is currently only available for horse
#' racing markets (e.g.venues=c("Exeter","Navan")). Codes can be obtained
#' via \code{\link{listVenues}}. Optional. Default is NULL.
#'
#' @param bspOnly Boolean. Restrict to betfair staring price (bsp) competitions
#' only if TRUE or non-bsp events if FALSE. Optional. Default is NULL, which
#' means that both bsp and non-bsp competitions are returned.
#'
#' @param turnInPlayEnabled Boolean. Restrict to competitions that will turn in
#' play if TRUE or will not turn in play if FALSE. Optional. Default is NULL,
#' which means that both competitions are returned.
#'
#' @param inPlayOnly Boolean. Restrict to competitions that are currently in
#' play if TRUE or not inplay if FALSE. Optional. Default is NULL, which means
#' that both inplay and non-inplay competitions are returned.
#'
#' @param marketBettingTypes vector <String>. Restrict to competitions that
#' match the betting type of the market (i.e. Odds, Asian Handicap Singles, or
#' Asian Handicap Doubles). Optional. Default is NULL. See
#' \url{https://api.developer.betfair.com/services/webapps/docs/display/1smk3cen4v3lu3yomq5qye0ni/Betting+Enums#BettingEnums-MarketBettingType}
#' for a full list (and description) of viable parameter values.
#'
#' @param withOrders String. Restrict to competitions in which the user has bets
#' of a specified status. The two viable values are "EXECUTION_COMPLETE" (an
#' order that does not have any remaining unmatched portion) and "EXECUTABLE"
#' (an order that has a remaining unmatched portion). Optional. Default is
#' NULL.
#'
#' @param textQuery String. Restrict competitions by any text associated with
#' the event type, such as the Name, Event, Competition, etc. The string can
#' include a wildcard (*) character as long as it is not the first character.
#' Optional. Default is NULL.
#'
#' @param suppress Boolean. By default, this parameter is set to FALSE, meaning
#' that a warning is posted when the listCompetitions call throws an error.
#' Changing this parameter to TRUE will suppress this warning.
#'
#' @param sslVerify Boolean. This argument defaults to TRUE and is optional. In
#' some cases, where users have a self signed SSL Certificate, for example
#' they may be behind a proxy server, Betfair will fail login with "SSL
#' certificate problem: self signed certificate in certificate chain". If this
#' error occurs you may set sslVerify to FALSE. This does open a small
#' security risk of a man-in-the-middle intercepting your login credentials.
#'
#' @return Response from Betfair is stored in the listCompetitions variable,
#' which is then parsed from JSON as a list. Only the first item of this list
#' contains the required event type identification details. If the
#' listCompetitions call throws an error, a data frame containing error
#' information is returned.
#'
#' @section Note on \code{listCompetitionsOps} variable: The
#' \code{listCompetitionsOps} variable is used to firstly build an R data
#' frame containing all the data to be passed to Betfair, in order for the
#' function to execute successfully. The data frame is then converted to JSON
#' and included in the HTTP POST request.
#'
#' @examples
#' \dontrun{
#' # Return all football and tennis competitions (and number of
#' corresponding markets) for the upcoming day.
#' listCompetitions(eventTypeIds = c("1","2"))
#'
#' # Return competitions that currently have at least one football market inplay.
#' listCompetitions(eventTypeIds = c("1"),inPlayOnly=TRUE)

#' specific football markets.
