Given the station ID number(s), this function retrieves data (time series in zoo format with accompanying metadata) from the WaterML2 service on the NRFA database. Gauged Daily Flow is measured in \(m^3\)/day.

gdf(id, metadata = FALSE, cl = NULL, verbose = FALSE)

Arguments

id

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

metadata

Logical, FALSE by default. If metadata = TRUE means that 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.

verbose

(FALSE by default). If set to TRUE prints GET request on the console.

Value

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