Proportional Symbols Typo Layer

Description

Plot a proportional symbols layer with colors based on qualitative data.

Usage

propSymbolsTypoLayer(
  x,
  spdf,
  df,
  spdfid = NULL,
  dfid = NULL,
  var,
  inches = 0.3,
  fixmax = NULL,
  symbols = "circle",
  border = "grey20",
  lwd = 1,
  var2,
  col = NULL,
  colNA = "white",
  legend.title.cex = 0.8,
  legend.values.cex = 0.6,
  legend.var.pos = "bottomleft",
  legend.var.title.txt = var,
  legend.values.rnd = 0,
  legend.var.style = "c",
  legend.var.frame = FALSE,
  legend.var2.pos = "topright",
  legend.var2.title.txt = var2,
  legend.var2.values.order = NULL,
  legend.var2.nodata = "no data",
  legend.var2.frame = FALSE,
  add = TRUE
)

Arguments

`x`	an sf object, a simple feature collection. If x is used then spdf, df, spdfid and dfid are not.
`spdf`	SpatialPointsDataFrame or SpatialPolygonsDataFrame; if spdf is a SpatialPolygonsDataFrame symbols are plotted on centroids.
`df`	a data frame that contains the values to plot. If df is missing spdf@data is used instead.
`spdfid`	name of the identifier variable in spdf, default to the first column of the spdf data frame. (optional)
`dfid`	name of the identifier variable in df, default to the first column of df. (optional)
`var`	name of the numeric variable used to plot the symbols sizes.
`inches`	size of the biggest symbol (radius for circles, width for squares, height for bars) in inches.
`fixmax`	value of the biggest symbol. (optional)
`symbols`	type of symbols, one of "circle", "square" or "bar".
`border`	color of symbols borders.
`lwd`	width of symbols borders.
`var2`	name of the factor (or character) variable used to plot the symbols colors.
`col`	a vector of colors.
`colNA`	no data color.
`legend.title.cex`	size of the legend title.
`legend.values.cex`	size of the values in the legend.
`legend.var.pos`	position of the legend, one of "topleft", "top", "topright", "right", "bottomright", "bottom", "bottomleft", "left" or a vector of two coordinates in map units (c(x, y)).
`legend.var.title.txt`	title of the legend (numeric data).
`legend.values.rnd`	number of decimal places of the values in the legend.
`legend.var.style`	either "c" or "e". The legend has two display styles, "c" stands for compact and "e" for extended.
`legend.var.frame`	whether to add a frame to the legend (TRUE) or not (FALSE).
`legend.var2.pos`	position of the legend, one of "topleft", "top", "topright", "right", "bottomright", "bottom", "bottomleft", "left" or a vector of two coordinates in map units (c(x, y)).
`legend.var2.title.txt`	title of the legend (factor data).
`legend.var2.values.order`	values order in the legend, a character vector that matches var modalities. Colors will be affected following this order.
`legend.var2.nodata`	text for "no data" values
`legend.var2.frame`	whether to add a frame to the legend (TRUE) or not (FALSE).
`add`	whether to add the layer to an existing plot (TRUE) or not (FALSE).

Examples

library(sf)
mtq <- st_read(system.file("gpkg/mtq.gpkg", package="cartography"))
# Countries plot
plot(st_geometry(mtq), col = "lightblue4",border = "lightblue3", 
     bg = "lightblue1")
# Population plot on proportional symbols
propSymbolsTypoLayer(x = mtq, var = "POP", var2 = "STATUS",
                     symbols = "circle",
                     col = c("aquamarine4", "yellow3","wheat"),
                     legend.var2.values.order = c("Prefecture",
                                                  "Sub-prefecture",
                                                  "Simple municipality"),
                     legend.var.pos = "right", border = "grey",
                     legend.var.title.txt = "Total\nPopulation")
layoutLayer(title = "Population Distribution in Martinique, 2015")
