The Flow Analysis Summary Statistics Tool for R (fasstr
) is a set of
R functions to tidy, summarize, analyze,
trend, and visualize streamflow data. This package summarizes continuous
daily mean streamflow data into various daily, monthly, annual, and
long-term statistics, completes annual trends and frequency analyses.
This package provides functions for streamflow data analysis, including:
- data tidying (to prepare data for analyses;
add_*
andfill_*
functions), - data screening (to identify data range, outliers and missing data;
screen_*
functions), - calculating summary statistics (long-term, annual, monthly and daily
statistics;
calc_*
functions), - computing analyses (volume frequency analyses and annual trending;
compute_*
functions), and, - visualizing data (plotting the various statistics;
plot_*
functions).
Useful features of functions include:
- the integration of the
tidyhydat
package to pull streamflow data from a Water Survey of Canada HYDAT database for analyses; - arguments for filtering of years and months in analyses and plotting;
- choosing the start month of your water year;
- selecting for rolling day averages (e.g. 7-day rolling average); and,
- choosing how missing dates are handled, amongst others.
This package is maintained by the Water Management Branch of the British Columbia Ministry of Water, Land and Resource Stewardship.
You can install fasstr
directly from
CRAN:
install.packages("fasstr")
To install the development version from
GitHub, use the
remotes
package then the
fasstr
package:
if(!requireNamespace("remotes")) install.packages("remotes")
remotes::install_github("bcgov/fasstr")
To use the station_number
argument and pull data directly from a
Water Survey of Canada HYDAT
database
into fasstr
functions, download a HYDAT file using the following code:
tidyhydat::download_hydat()
There are several vignettes and a cheatsheet to provide more information
on the usage of fasstr
functions and how to customize various argument
options.
