ec_norm_plot

Plot normalised ecological indicator values against the raw variable values

Usage

ec_norm_plot(variable, indicator, lan = "english")

Arguments

variable

Numeric vector of raw variable values.

indicator

Numeric vector of normalised indicator values, typically produced by ec_normalise_dev().

lan

Character. Plot language. One of "english" or "norsk". Defaults to "english".

Value

A ggplot2 object.

Details

Creates a scatter plot comparing raw variable values and corresponding normalised indicator values produced by ec_normalise_dev().

The plot is intended as a simple diagnostic and visualisation tool for evaluating ecological normalisation functions.

Points are coloured according to the indicator value using a red-to-green colour gradient.

The function returns a ggplot2 object and can therefore be further modified using standard ggplot2 syntax.

Examples

x <- seq(0, 1000, by = 2)

ind <- ec_normalise(
  variable = x,
  x0 = 100,
  x100 = 900,
  x60 = 200
)

ec_norm_plot(
  variable = x,
  indicator = ind,
  lan = "norsk"
)


ind <- ec_normalise(
  variable = x,
  x0 = 50,
  x100 = rnorm(n = length(x), 400, 50),
  x0h = 900,
  fun = "sigmoid"
)

ec_norm_plot(
  variable = x,
  indicator = ind
)
