Function for plotting terciles

Description

Function for plotting terciles

Usage

tercile_plot(
  dt,
  data_col = tc_cols(dt),
  mn = NULL,
  low = "orange",
  mid = "cyan",
  high = "green1",
  name = "",
  labels = c("Wetter", "Average", "Drier"),
  na.value = "white",
  extent = NULL,
  expand.x = c(-0.5, 0.5),
  expand.y = c(-0.5, 2),
  dimension_check = TRUE
)

Arguments

dt	data table
data_col	Name of the column containing the observed tercile category
mn	optional title for the plot.
low, mid, high	colors for the three categories
name	optional title for the colorscale
labels	How to label the three categories
na.value	How to color missing values
extent	Optional vector of length 4 specifying the plotting borders in order xmin, xmax, ymin, ymax.
expand.x, expand.y	How far should the plotting borders be extended (beyond the data range)?
dimension_check	Logical. By default the function checks that there are not multiple values per coordinate (and subsets to the first level if there are several, e.g. to the first year and month (by appearance in dt) if dt contains data for several years and months).

Examples

dt = chirps_monthly[month == 12 & lat <0 & year == 2018]
p = tercile_plot(dt = dt)
if(interactive()) plot(p)
