This function retrieves time series data.

Source: R/get_ts.R

Given the station identification number(s), this function retrieves data (time series in zoo format with accompanying metadata) from the WaterML2 service on the NRFA database. The time series can be of two types: cmr (catchment mean rainfall, monthly) or gdf (gauged daily flows, daily).

get_ts(id, type, metadata = FALSE, cl = NULL, full_info = FALSE)

Arguments

id

station identification number(s), each number should be in the range [3002,236051].

type

The following data-types are available:

  • gdf = Gauged daily flows

  • gmf = Gauged monthly flows

  • ndf = Naturalised daily flows

  • nmf = Naturalised monthly flows

  • cdr = Catchment daily rainfall

  • cmr = Catchment monthly rainfall

  • pot-stage = Peaks over threshold stage

  • pot-flow = Peaks over threshold flow

  • gauging-stage = Gauging stage

  • gauging-flow = Gauging flow

  • amax-stage = Annual maxima stage

  • amax-flow = Annual maxima flow

metadata

Logical, FALSE by default. When metadata = TRUE the result for a single station is a list with two elements: data (the time series) and meta (metadata).

cl

(optional) This is a cluster object, created by the parallel package. This is set to NULL by default, which sends sequential calls to the server.

full_info

Logical, FALSE by default. If full_info = TRUE, the function will retrieve information on rejected periods.

Value

list composed of as many objects as in the list of station identification numbers. Each object can be accessed using their names or indexes (e.g. x[[1]], x[[2]], and so forth). Each object contains a time series of class zoo/xts.
