Deprecated - Plot symbols — mf

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

Plot symbols based on qualitative data.

Usage

mf_symb(
  x,
  var,
  pal,
  alpha = NULL,
  rev = FALSE,
  border,
  pch,
  cex = 2,
  lwd = 0.7,
  col_na = "grey",
  pch_na = 4,
  cex_na = 1,
  val_order,
  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_no_data = "No data",
  leg_frame = FALSE,
  leg_frame_border,
  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
pal: a set of colors (hex codes) or a palette name (valid palette names can be obtained with hcl.pals).
alpha: opacity, in the range 0,1
rev: if pal is a valid palette name, whether the ordering of the colors should be reversed (TRUE) or not (FALSE)
border: border color
pch: pch (point type) for symbols
cex: cex (point size) for symbols
lwd: border width
col_na: color for missing values
pch_na: point type for NA values
cex_na: point size for NA values
val_order: values order, a character vector that matches var modalities
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_no_data: label for missing values
leg_frame: whether to add a frame to the legend (TRUE) or not (FALSE)
leg_frame_border: border color of the legend frame
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, "STATUS", "symb")


mtq[6, "STATUS"] <- NA
mf_map(mtq)
mf_map(
  x = mtq, var = "STATUS", type = "symb",
  pch = c(21:23), pal = c("red1", "tan1", "khaki1"),
  border = "grey20", cex = c(1.5, 1, .9), lwd = .5,
  val_order = c("Prefecture", "Sub-prefecture", "Simple municipality"),
  pch_na = 24, leg_frame = TRUE
)
