Typology Layer

Description

Plot a typology layer.

Usage

typoLayer(
  x,
  spdf,
  df,
  spdfid = NULL,
  dfid = NULL,
  var,
  col = NULL,
  border = "grey20",
  lwd = 1,
  colNA = "white",
  legend.pos = "bottomleft",
  legend.title.txt = var,
  legend.title.cex = 0.8,
  legend.values.cex = 0.6,
  legend.values.order = NULL,
  legend.nodata = "no data",
  legend.frame = FALSE,
  add = FALSE
)

Arguments

x	an sf object, a simple feature collection. If x is used then spdf, df, spdfid and dfid are not.
spdf	a SpatialPolygonsDataFrame.
df	a data frame that contains the values to plot. If df is missing spdf@data is used instead.
spdfid	name of the identifier variable in spdf, default to the first column of the spdf data frame. (optional)
dfid	name of the identifier variable in df, default to the first column of df. (optional)
var	name of the variable to plot.
col	a vector of colors.
border	color of the polygons borders.
lwd	borders width.
colNA	no data color.
legend.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 legend.pos is "n" then the legend is not plotted.
legend.title.txt	title of the legend.
legend.title.cex	size of the legend title.
legend.values.cex	size of the values in the legend.
legend.values.order	values order in the legend, a character vector that matches var modalities. Colors will be affected following this order.
legend.nodata	no data label.
legend.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).

                                  "Simple municipality"),

          legend.title.txt = "Status")
