In GJMeijer/soilmech: R functions and plots for Soil Mechanics teaching

Add surfaces to a ggplot object

Description

Function to make it faster to add a series of soil, water or structure surfaces to an existing ggplot object

Usage

ggplot_add_surface(
  plt,
  df,
  type = "soil",
  colour = NULL,
  fill = NULL,
  linetype = NULL,
  linesize = 0.5,
  linesize_marker = 0.3,
  settings = tibble::tibble(id = c("soil", "water", "structure"), fill = c("#d3bc5f",
    "#2a7fff", "#333333"), colour = c("#65571d", "#000080", "#000000"), linetype = c(1,
    2, 1), pos_marker = c(1/3, 2/3, 1/2), scale_marker = c(0.075, 0.05, 0.05))
)

Arguments

plt	ggplot to be added to
df	tibble with data. Should contain fields 'x' and 'y' for polygon point positions. May contain optional field 'group' to differentiate between different polygons
type	either 'soil', 'water' or 'structure'. This setting is used to determine the fill colour of the polygons
colour	if specied, overrides the colour settings defined through the 'settings' settings
fill	if specified, overrides the fill colour defined through the 'settings' settings
linetype	if specied, overrides the linetype settings defined through the 'settings' settings
linesize	line size thickness
linesize_marker	thickness of lines in surface marker elements
settings	dataframe with default settings for soil, water and structure elements

Value

ggplot object
