Description

Plot graduated symbols based on quantitative data.

Usage

mf_grad(
  x,
  var,
  breaks = "quantile",
  nbreaks = 3,
  col = "tomato4",
  border,
  pch = 21,
  cex,
  lwd,
  leg_pos = mf_get_leg_pos(x),
  leg_title = var,
  leg_title_cex = 0.8,
  leg_val_cex = 0.6,
  leg_val_rnd = 2,
  leg_frame = FALSE,
  add
)

Arguments

x

object of class sf

var

name(s) of the variable(s) to plot

breaks

either a numeric vector with the actual breaks, or a classification method name (see mf_get_breaks)

nbreaks

number of classes

col

pch

pch for symbols

cex

cex for symbols

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)). If leg_pos is 'n' then the legend is not plotted.

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_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)

Value

No return value, a map is displayed.

Examples

# NOT RUN {
mtq <- mf_get_mtq()
mf_map(mtq)
mf_grad(mtq, "POP", pch = 22)
# }
