spLayer.SpatialPoints: Define a Vector Data Layer

Description

spLayer.SpatialPoints defines a new data layer from an object SpatialPoints or SpatialPointsDataFrame
spLayer.SpatialLines defines a new data layer from an object SpatialLines or SpatialLinesDataFrame
spLayer.SpatialPolygons defines a new data layer from an object SpatialPolygons or SpatialPolygonsDataFrame

Usage

# S3 method for SpatialPoints
spLayer(x, name = NULL, png = NULL, size = 5,
  png.width = 15, png.height = 15, stroke = TRUE, stroke.col = 1,
  stroke.lwd = 1, stroke.lty = -1, stroke.alpha = 1, fill = TRUE,
  fill.col = 2, fill.alpha = 0.5, label = NULL, popup = "",
  popup.rmd = FALSE, legend = NULL, ...)

Arguments

x: a spatial object (see Details).
name: a character string to name the layer.
png: character vector giving the paths for the PNG icons. If NULL (default), circles are drawn.
size: a numerical vector giving the size of points (radius in pixels).
png.width,png.height: numerical vectors giving the PNG icons dimensions on the map (in pixels).
stroke: logical. Should a stroke be drawn along lines and polygons?
stroke.col: a vector of any of the three kinds of R color specifications to set strokes color.
stroke.lwd: a numerical vector to set strokes width.
stroke.lty: a character vector that defines the strokes dash patterns (See Details).
stroke.alpha: a vector of numeric values in \([0, 1]\) setting strokes opacity.
fill: logical. Should points and polygons be filled?
fill.col: a vector of any of the three kinds of R color specifications to set fill colors.
fill.alpha: a vector of numeric values in \([0, 1]\) setting fill opacity.
label: a reserved argument (in development).
popup: a character vector giving contents for popups. HTML tags are accepted.
popup.rmd: a logical indicating whether the popups should be processed as R Markdown with knitr. Default FALSE.
legend: a legend object created with layerLegend.
...: additional arguments to pass to the function.
