readWQPdata.R

#' General Data Import from Water Quality Portal
#'
#' Imports data from Water Quality Portal web service. This function gets the data from here:
#' \url{https://www.waterqualitydata.us}.
#' 
#' This function uses \dots as a query input, which can be very flexible, but also 
#' has a steeper learning curve. For a quick overview, scroll down to the Examples
#' in this help file to see many query options. 
#' 
#' @details
#'  
#' There are currently 10 legacy options
#' for data provided by the Water Quality Portal:
#'  
#' 
#' Legacy:
#' \tabular{lll}{
#' WQP Radio Button \tab service argument \tab Base URL  \cr
#' Sample Results \tab Result \tab /data/Result/search \cr
#' Site Data Only \tab Station \tab /data/Station/search \cr
#' Sampling Activity \tab Activity \tab /data/Activity/search \cr
#' Sampling Activity Metrics \tab ActivityMetric \tab /data/ActivityMetric/search \cr
#' Site Summary (not advertised on WQP)  \tab SiteSummary \tab /data/summary/monitoringLocation/search \cr
#' Project Data \tab Project \tab /data/Project/search \cr
#' Project Monitoring Location Weighting Data \tab ProjectMonitoringLocationWeighting \tab /data/ProjectMonitoringLocationWeighting/search \cr
#' Result Detection Quantitation Limit Data \tab ResultDetectionQuantitationLimit \tab /data/ResultDetectionQuantitationLimit/search \cr
#' Biological Habitat Metrics \tab BiologicalMetric \tab /data/BiologicalMetric/search \cr
#' Organization Data \tab Organization \tab /data/Organization/search \cr
#' }
#' 
#' There are 4 WQX3 options. These are still in-development,
#' and should be used with caution.
#'  
#' \tabular{llll}{
#' WQP Radio Button \tab service argument \tab Base URL \tab dataProfile \cr 
#' Monitoring Locations \tab StationWQX3 \tab /wqx3/Station/search \tab \cr
#' Full Physical Chemical \tab ResultWQX3 \tab /wqx3/Result/search \tab fullPhysChem \cr
#' Narrow \tab ResultWQX3 \tab /wqx3/Result/search \tab narrow \cr
#' Basic Physical Chemical \tab ResultWQX3 \tab /wqx3/Result/search \tab basicPhysChem \cr
#' Sampling Activity \tab ActivityWQX3 \tab /wqx3/Activity/search \cr
#' }
#' 
#'
#' @param \dots see \url{https://www.waterqualitydata.us/webservices_documentation} for a complete list of options.
#' A list of arguments can also be supplied. For more information see the above 
#' description for this help file. If no "service" argument is supplied, it
#' will default to "ResultWQX3". One way to figure out how to construct a WQP query is to go to the "Advanced" 
#' form in the Water Quality Portal. Use the form to discover what parameters are available. Once the query is 
#' set in the form, scroll down to the "Query URL". You will see the parameters
#' after "https://www.waterqualitydata.us/#". For example, if you chose "Nutrient"
#' in the Characteristic Group dropdown, you will see characteristicType=Nutrient
#' in the Query URL. The corresponding argument for dataRetrieval is
#' characteristicType = "Nutrient". dataRetrieval users do not need to include
#' mimeType, and providers is optional (these arguments are picked automatically).
#' @param service character. See Details for more information.
#' @param querySummary logical to only return the number of records and unique sites that
#' will be returned from this query. Choosing TRUE is deprecated, readWQPsummary 
#' is recommended instead.
#' @param tz character to set timezone attribute of dateTime. Default is "UTC", and converts the
#' date times to UTC, properly accounting for daylight savings times based on the
#' data's provided tz_cd column.
#' Possible values to provide are "America/New_York","America/Chicago",
#' "America/Denver","America/Los_Angeles",
#' "America/Anchorage", as well as the following which do not use daylight savings
#' time: "America/Honolulu",
#' "America/Jamaica","America/Managua","America/Phoenix", and "America/Metlakatla".
#' See also  \code{OlsonNames()}
#' for more information on time zones.
#' @param ignore_attributes logical to choose to ignore fetching site and status
#' attributes. Default is \code{FALSE}.
#' @param convertType logical, defaults to \code{TRUE}. If \code{TRUE}, the function
#' will convert the data to dates, datetimes,
#' numerics based on a standard algorithm. If false, everything is returned as a character.
#' @keywords data import WQP web service
#' @return A data frame, the specific columns will depend on the "service" and/or "dataProfile".
#'
#' There are also several useful attributes attached to the data frame:
#' \tabular{lll}{
#' Name \tab Type \tab Description \cr
#' url \tab character \tab The url used to generate the data \cr
#' siteInfo \tab data.frame \tab A data frame containing information on the requested sites \cr
#' headerInfo \tab data.frame \tab A data frame returned from the WQP status service \cr
#' queryTime \tab POSIXct \tab The time the data was returned \cr
