R Documentation

Plot minimum runoff month

Description

Generate a histogram of a minimum runoff month for two periods: before and after the change year set by year parameter.

Usage

gr_plot_minmonth(
  df,
  year = NULL,
  exclude = NULL,
  tests = NULL,
  pagebreak = FALSE,
  print = TRUE
)

Arguments

`df`	`data.frame` of hydrograph and meteorological variables as produced by `gr_summarize()`.
`year`	Integer. Change year value to separate two periods.
`exclude`	Integer vector of years to be excluded from plotting.
`tests`	Tests list for the same variables (generated by `gr_test_vars()` function)
`pagebreak`	Logical. Whether to break page between plots (needed for reporting). Defaults to `FALSE`.
`print`	Boolean. Print plot? Defaults to `TRUE`. Use `FALSE` if you want to tweak the plot aesthetics before plotting.

Value

list of two ggplot2 objects, representing the histogram of a minimum runoff month for two periods: before and after the change year

Examples

library(grwat)

data(spas) # example Spas-Zagorye data is included with grwat package

# separate
sep = gr_separate(spas, params = gr_get_params(reg = 'center'))

# summarize from 1965 to 1990
vars = gr_summarize(sep, 1965, 1990)

# plot minimum runoff month for two periods divided by Pettitt test
gr_plot_minmonth(vars, tests = gr_test_vars(vars))

# plot minimum runoff month for two periods divided by fixed year
gr_plot_minmonth(vars, year = 1978)
