Deprecated - Plot proportional symbols

This function is deprecated. Please use mf_map() with type = "prop" instead.

Plot proportional symbols.

Usage

mf_prop(
  x,
  var,
  inches = 0.3,
  val_max,
  lwd_max = 20,
  symbol = "circle",
  col,
  alpha = NULL,
  border,
  lwd = 0.7,
  extent = x,
  bg,
  expandBB = rep(0.04, 4),
  leg_pos = mf_get_leg_pos(x),
  leg_title = var,
  leg_title_cex = 0.8,
  leg_val_cex = 0.6,
  leg_val_rnd = 0,
  leg_val_dec = ".",
  leg_val_big = "",
  leg_frame = FALSE,
  leg_frame_border,
  leg_horiz = FALSE,
  leg_adj = c(0, 0),
  leg_fg,
  leg_bg,
  leg_size = 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
lwd_max: line width of the largest line
symbol: type of symbols, 'circle' or 'square'
col: a color, hex code or color name given by colors
alpha: opacity, in the range 0,1
border: border color
lwd: border width
leg_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)). Use NA to avoid plotting the legend, use 'interactive' to choose the legend position by clicking on the map.
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_val_dec: decimal separator
leg_val_big: thousands separator
leg_frame: whether to add a frame to the legend (TRUE) or not (FALSE)
leg_frame_border: border color of the legend frame
leg_horiz: display the legend horizontally (for proportional symbols and choropleth types)
leg_adj: adjust the position of the legend in x and y directions
leg_fg: color of the legend foreground
leg_bg: color of the legend background
leg_size: size of the legend; 2 means two times bigger
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, "POP", "prop")


mf_map(mtq)
mf_map(
  x = mtq, var = "POP", type = "prop",
  inches = .4, symbol = "circle", val_max = 90000,
  col = "tomato1", border = "blue", lwd = 1,
  leg_pos = "right", leg_title = "Population",
  leg_title_cex = 1, leg_val_cex = .8, leg_val_rnd = 0,
  leg_frame = TRUE, add = TRUE
)
