Downloading daily, and monthly hydrological data from the measurement stations available in the danepubliczne.imgw.pl collection
hydro_imgw(interval, year, value = "H", station = NULL, ...)temporal resolution of the data ("daily" or "monthly")
vector of years (e.g., 1966:2000)
type of data (can be: state - "H" (default), flow - "Q", or temperature - "T")
vector of hydrological stations danepubliczne.imgw.pl; can be given as station name with CAPITAL LETTERS (character) It accepts either names (characters in CAPITAL LETTERS) or stations' IDs (numeric)
other parameters that may be passed e.g. to the 'shortening' function that shortens column names
A data.frame with columns describing the hydrological parameters
(e.g. flow, water level) where each row represent a measurement,
