Plot goodness-of-fit graph

Source: R/gof_graph.R

Produces a goodness-of-fit statistic graph for the specified reach for analysis regions specified by the build_gof_stats function.

gof_graph(gof_stats, stream, bankfull_elevation, stat = "MAE")

Arguments

gof_stats

data frame; A gof_stats data frame. See the build_gof_stats function for details on how to create.

stream

character; The name of the stream.

bankfull_elevation

numeric; The detrended bankfull elevation (in feet) that is used to calculate hydraulic geometry.

stat

character; The statistic to graph "RMSE", "MAE" (the default).

Value

A ggplot object.

Details

Add a discussion of how to interpret the graph.

Examples

# Extract attribute data from the fluvgeo::sin_xs_points sf dataframe
sin_xs_points_df <- fluvgeo::sin_riffle_channel_points_sf

# Set variable values
streams <- c("Sinsinawa")
regions <- c("Eastern United States", "IN Central Till Plain")
bankfull_elevations = seq(103, 104, 0.1)

# Call the xs_dimensions function
sin <- xs_dimensions(xs_points = sin_xs_points_df,
                     streams = streams,
                     regions = regions,
                     bankfull_elevations = bankfull_elevations)

# Call the build_gof_stats function
sin_gof <- build_gof_stats(xs_dims = sin,
                           streams = streams,
                           regions = regions,
                           bankfull_elevations = bankfull_elevations)

# Call the gof_graph function
sin_gof_graph <- gof_graph(gof_stats = sin_gof,
                           stream = streams,
                           bankfull_elevation = 103.5,
                           stat = "MAE")
