mf_prop_typo: Plot proportional symbols using typology coloration

In mapsf: Thematic Cartography

Plot proportional symbols using typology coloration

Description

Plot proportional symbols with colors based on qualitative data.

Usage

mf_prop_typo(
  x,
  var,
  inches = 0.3,
  val_max,
  symbol = "circle",
  pal = "Dynamic",
  alpha = 1,
  rev = FALSE,
  val_order,
  border = getOption("mapsf.fg"),
  lwd = 0.7,
  lwd_max = 15,
  col_na = "white",
  leg_pos = mf_get_leg_pos(x, 1),
  leg_title = var,
  leg_title_cex = c(0.8, 0.8),
  leg_val_cex = c(0.6, 0.6),
  leg_val_rnd = c(0),
  leg_no_data = "No data",
  leg_frame = c(FALSE, FALSE),
  leg_frame_border = getOption("mapsf.fg"),
  leg_horiz = FALSE,
  leg_adj = c(0, 0),
  leg_fg = getOption("mapsf.fg"),
  leg_bg = getOption("mapsf.bg"),
  leg_size = 1,
  leg_box_border = getOption("mapsf.fg"),
  leg_box_cex = c(1, 1),
  add = TRUE
)

Arguments

x	object of class sf
var	name(s) of the variable(s) to plot
inches	size of the biggest symbol (radius for circles, half width for squares) in inches.
val_max	maximum value used for proportional symbols
symbol	type of symbols, 'circle' or 'square'
pal	a set of colors or a palette name (from hcl.colors)
alpha	if pal is a hcl.colors palette name, the alpha-transparency level in the range [0,1]
rev	if pal is a hcl.colors palette name, whether the ordering of the colors should be reversed (TRUE) or not (FALSE)
val_order	values order, a character vector that matches var modalities
border	border color
lwd	border width
lwd_max	line width of the largest line
col_na	color for missing values
leg_pos	position of the legend, two of 'topleft', 'top','topright', 'right','bottomright', 'bottom', 'bottomleft', 'left' or a vector of two coordinates in map units (c(x, y)). leg_pos argument can be c('position', 'position'), c('position', x2, y2), c(x1,y1, 'position') or c(x1, y1, x2, y2). Use NA to avoid plotting the legend, use 'interactive' to choose thelegend position interactively.
leg_title	legend title
leg_title_cex	size of the legend title
leg_val_cex	size of the values in the legend
leg_val_rnd	number of decimal places of the values in the legend
leg_no_data	label for missing values
leg_frame	whether to add a frame to the legend (TRUE) or not (FALSE)
leg_horiz	display the legend horizontally (for proportional symbols and choropleth types)
leg_adj	adjust the postion of the legend in x and y directions
add	whether to add the layer to an existing plot (TRUE) or not (FALSE)

Value

x is (invisibly) returned.

Examples

mtq <- mf_get_mtq()
mf_map(mtq)
mf_map(mtq, c("POP", "STATUS"), "prop_typo")

mtq[6, "STATUS"] <- NA
mf_map(mtq)
mf_map(
  x = mtq, var = c("POP", "STATUS"), type = "prop_typo",
  inches = .35, border = "tomato4",
  val_max = 90000, symbol = "circle", col_na = "grey", pal = "Dynamic",
  lwd = 2,
  leg_pos = c("bottomright", "bottomleft"),
  leg_title = c("Population", "Municipality\nstatus"),
  leg_title_cex = c(0.9, 0.9),
  leg_val_cex = c(.7, .7),
  val_order = c("Prefecture", "Sub-prefecture", "Simple municipality"),
  leg_no_data = "No dada",
  leg_frame = c(TRUE, TRUE),
  add = TRUE
)
