Basic Water Quality Portal Data parser

Description

Imports data from the Water Quality Portal based on a specified url.

Usage

importWQP(obs_url, tz = "UTC", csv = TRUE, convertType = TRUE)

Arguments

obs_url	character URL to Water Quality Portal#' @keywords data import USGS web service
tz	character to set timezone attribute of datetime. Default is UTC (properly accounting for daylight savings times based on the data's provided tz_cd column). Possible values include "America/New_York","America/Chicago", "America/Denver","America/Los_Angeles", "America/Anchorage","America/Honolulu","America/Jamaica","America/Managua", "America/Phoenix", and "America/Metlakatla"
csv	logical. Is the data coming back with a csv or tsv format. Default is FALSE. Currently, the summary service does not support tsv, for other services tsv is the safer choice.
convertType	logical, defaults to TRUE. If TRUE, the function will convert the data to dates, datetimes, numerics based on a standard algorithm. If false, everything is returned as a character.

Value

retval dataframe raw data returned from the Water Quality Portal. Additionally, a POSIXct dateTime column is supplied for start and end times, and converted to UTC. See https://www.waterqualitydata.us/portal_userguide/ for more information.
