Plot symbols

Description

Plot symbols based on qualitative data.

Usage

mf_symb(
  x,
  var,
  pal = "Dynamic",
  alpha = 1,
  rev = FALSE,
  border = getOption("mapsf.fg"),
  pch,
  cex = 1,
  lwd = 0.7,
  col_na = "grey",
  pch_na = 4,
  cex_na = 1,
  val_order,
  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_no_data = "No data",
  leg_frame = FALSE,
  leg_frame_border = getOption("mapsf.fg"),
  leg_adj = c(0, 0),
  leg_fg = getOption("mapsf.fg"),
  leg_bg = getOption("mapsf.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 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)
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	pch (point type) for NA values
cex_na	cex (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)). If leg_pos = NA then the legend is not plotted. If leg_pos = 'interactive' click onthe map to choose the legend position.
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_frame_border	border color of the legend frame
leg_adj	adjust the postion of the legend in x and y directions
leg_fg	color of the legend foreground
leg_bg	color of the legend backgournd
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
)
