What does tidyhydat do?

Installation

You can install tidyhydat from CRAN:

install.packages("tidyhydat")

To install the development version of the tidyhydat package, you can install directly from the rOpenSci development server:

install.packages("tidyhydat", repos = "https://dev.ropensci.org")

Usage

More documentation on tidyhydat can found at the rOpenSci doc page: https://docs.ropensci.org/tidyhydat/

When you install tidyhydat, several other packages will be installed as well. One of those packages, dplyr, is useful for data manipulations and is used regularly here. To use actually use dplyr in a session you must explicitly load it. A helpful dplyr tutorial can be found here.

library(tidyhydat)
library(dplyr)

HYDAT download

To use many of the functions in the tidyhydat package you will need to download a version of the HYDAT database, Environment and Climate Change Canada’s database of historical hydrometric data then tell R where to find the database. Conveniently tidyhydat does all this for you via:

download_hydat()

This downloads (with your permission) the most recent version of HYDAT and then saves it in a location on your computer where tidyhydat’s function will look for it. Do be patient though as this can take a long time! To see where HYDAT was saved you can run hy_default_db(). Now that you have HYDAT downloaded and ready to go, you are all set to begin looking at Canadian hydrometric data.

Real-time

To download real-time data using the datamart we can use approximately the same conventions discussed above. Using realtime_dd() we can easily select specific stations by supplying a station of interest:

realtime_dd(station_number = "08LG006")

Plotting

Plot methods are also provided to quickly visualize realtime data:

realtime_ex <- realtime_dd(station_number = "08LG006")

plot(realtime_ex)

and also historical data:

hy_ex <- hy_daily_flows(station_number = "08LA001", start_date = "2013-01-01")

plot(hy_ex)
