getValues: Get the values of one/several elements at one/several...

In nexModeling/wsklimaR: Easy access to wsklima service (open-data from met.no)

Description

The function getValues() makes it possible to get timeseries of meteorological elements at some given stations registered by met.no for a specific period of time and a specific time resolution.

Usage

getValues(timeserietypeID = NULL, fromPeriod = NULL, toPeriod = NULL,
  stations = NULL, elements = NULL, missingValues = -999)

Arguments

timeserietypeID	0:Daily, 1:Monthly, 2:Hourly, 3:Normal Monthly, 4: Normal Daily, 5:Record Daily (not used)
fromPeriod	string of character yyyymmdd. Omitting this parameter will make it start 3 days earlier from now
toPeriod	string of character yyyymmdd. Omitting this parameter will make it stop now
stations	id of the stations. Can be a scalar or a vector of station ids
elements	meteorlogical element as its code ("TAM", "RR", ...). Can be a vector of elements
missingValues	value of the expected mssing values. By default: -999

Details

rem: timeserietypeID #2 is not always representing the hourly time resolution but also can be infra-hourly. We only keep hourly datasets.

Value

The output is a dataframe structured as followed: the date timeserie, and the elements. Each element is a dataframe made of the timeseries of the different stations. This structure eases the conversion into a json format
