plot_statespace_ch: Convex hull plot

In saskiaotto/INDperform: Evaluation of Indicator Performances for Assessing Ecosystem States

Description

plot_statespace_ch generates a scatter plot of all observed combinations in the 2-dimensional indicator space including the convex hull from defined reference conditions and the current period.

Usage

plot_statespace_ch(x, col_ch_ref = "red", col_ch_cur = "blue", size_time = 4)

Arguments

x	An object from the statespace_ch function.
col_ch_ref	Color of reference period (for points, path, and labels).
col_ch_cur	Color of current period (for points, path, and labels).
size_time	Text size of the time labels (both periods).

Value

The function returns a ggplot object.

Examples

# Using the Baltic Sea demo data in the package
x <- statespace_ch(x = ind_ex$TZA, y = ind_ex$MS,
  time = ind_ex$Year, period_ref = 1979:1983,
  period_current = 2004:2008)
plot_statespace_ch(x)

# To modify the plot:
p <- plot_statespace_ch(x, col_ch_ref = "green4", col_ch_cur = "orange3",
  size_time = 6)
p + ggplot2::xlab("TZA") + ggplot2::ylab("MS") +
  ggplot2::ggtitle("Deviation of current state from reference period") +
  ggplot2::theme(plot.title = ggplot2::element_text(size = 10)) +
  ggplot2::theme(axis.text = ggplot2::element_text(size = 6),
    axis.title = ggplot2::element_text(size = 20))
