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).

                                  "Sub-prefecture", 
                                  "Simple municipality"),
          legend.pos = "topright",
          legend.title.txt = "Status")
layoutLayer(title = "Municipality Status")
