plot_bias: Plots bias vs. exposure level

In jschap1/WSEw: River Geometry Package for Studying Water Surface Elevation-Width Relationships

Description

Also calculates bias

Usage

plot_bias(expo, pred_vals, true_vals, na.rm = TRUE, ...)

Arguments

expo	vector of exposure levels
pred_vals	predicted values of bottom elevation, flow area, wetted perimeter, etc. A list with 5 elements.
true_vals	true values
...	other arguments supported by plot

Details

Must be five pred_vals inputs, corresponding to the linear, slope break, multiple slope break, nonlinear, and nlsb methods

Value

bias a data frame showing bias at each exposure level, averaged across all river reaches

Examples

pred_z0 <- list(z0.l, z0.sb, z0.nl, z0.nlsb)
plot_bias(expo, pred_z0, z0.true, na.rm = TRUE, 
         main = "z0 bias vs. exposure level, no meas. error", ylab = "Bias (m)", ylim = c(-2,2))
