Bubble plot for spatial data with attributes. This is a wrapper around bubble in the sp package.

PlotBubble(pts, zcol, ply, xlim = bbox(ply)[1, ], ylim = bbox(ply)[2, ],
           main = "", gr.type = "windows", gr.file = NULL,
           projargs = proj4string(pts))

`pts`	`SpatialPointsDataFrame`; the data at the observation sites.
`zcol`	`character`; the z-variable column name in attribute table of `pts`.
`ply`	`SpatialPolygonsDataFrame`; a polygon to include in layout.
`xlim`	`numeric`; a vector of length 2 giving left and right limits for the x-axis.
`ylim`	`numeric`; a vector of length 2 giving lower and upper limits for the y-axis.
`main`	`character`; the main plot title to be placed on top.
`gr.type`	`character`; the name of a graphics driver, either "postscript", "pdf", "png", or the default "windows".
`gr.file`	`character`; the path of a file for writing the graphics, only used if `gr.type` is not "windows".
`projargs`	`character`; the projection arguments; the arguments must be entered exactly as in the PROJ.4 documentation.

Returns (or plots) the bubble plot. Values plotted in the key include the five quantiles: minimum, 25th percentile, median, 75th percentile, and maximum.
