|---|---|
| Description: | The Flow Analysis Summary Statistics Tool for R, 'fasstr', provides various functions to tidy and screen daily stream discharge data, calculate and visualize various summary statistics and metrics, and compute annual trending and volume frequency analyses. It features useful function arguments for filtering of and handling dates, customizing data and metrics, and the ability to pull daily data directly from the Water Survey of Canada hydrometric database (<https://collaboration.cmc.ec.gc.ca/cmc/hydrometrics/www/>). |

Add a column of rolling daily cumulative volumetric flows on an annual basis to a daily streamflow data set. Adds the volumetric discharge from each day with the previous day(s) for each year, in units of cubic metres.

Adds selected n-day rolling means to a daily streamflow data set. Based on selected n-days and alignment, the rolling
mean for a given day is obtained by averaging the adjacent dates of daily mean values. For example, rolling days of '7'
and 'right' alignment would obtain a mean of the given and previous 6 days of daily mean flow.

Adds a column of seasons identifiers to a data frame with a column of dates called 'Date'. The length of seasons,
in months, is provided using the seasons_length argument. As seasons are grouped by months the length of the seasons
must be divisible into 12 with one of the following season lengths: 1, 2, 3, 4, 6, or 12 months. The start of the first season

Calculates annual and seasonal total flows, as volumetric discharge or water yields, from a daily streamflow data set. For water year and seasonal data, the year is identified by the year in which the year or season ends. Two-seasons and four-seasons per year are calculated, with each 6 and 3-month seasons starting with the first month of the year (Jan for calendar year, specified for water year). Each season is designated by the calendar or water year in which it occurs. Calculates statistics from all values from complete years, unless specified. Returns a tibble with statistics.

Plots means, medians, maximums, minimums, and percentiles as ribbons for each month of all years of flow values
from a daily streamflow data set. Calculates statistics from all values, unless specified. Data calculated using the
calc_monthly_stats() function. Produces a list containing a plot for each statistic. Returns a list of plots.

Calculates and writes tables and plots from a suite of statistics from fasstr functions into
an Excel workbook, and accompanying plot files for certain analyses. Due to the number of tables and plots to be made, this
function may take several minutes to complete. If ignore_missing = FALSE (default) and there is missing data,
some tables and plots may be empty and produce warnings. Use ignore_missing = TRUE to ignore the missing values or
filter your data to complete years. Calculates statistics from all values, unless specified. Returns a list of tibbles and
plots, along with saving the Excel and image files in a directory.
