Introduction

The waterDataSupport package is intended to simplify normally complex tasks associated with collecting data.

Because the goal of the package is simplicity, it is intended to be less robust than the original code on which it is based.

library(waterDataSupport)

The as.International.Date() function has only one input which is a date in international format. International format (YY/mm/dd) is recommended to avoid confusion with other formats.

BEGIN_DATE = as.International.Date("1992/1/1")
END_DATE = as.International.Date("2022/12/1")

The Select_NOAA_Stations function downloads selected stations from NOAA

If a message concerning cached files show up, check the date to ensure it is recent.

VARS_NOAA <- c("PRCP", "TMAX", "TMIN")

stations1 <- Select_NOAA_Stations(refresh = FALSE,
                                 selectElements = VARS_NOAA,
                                 beginYear = as.Year(BEGIN_DATE),
                                 endYear = as.Year(END_DATE))

VARS_NOAA <- c("PRCP", "TMAX", "TMIN")

stations2 <- Select_NOAA_Stations(
  refresh = FALSE,
  selectElements = VARS_NOAA,
  beginYear = as.Year(BEGIN_DATE),
  endYear = as.Year(END_DATE),
  unique_stations = TRUE
)
