grid.hexlegend.RdPlots the legend for the plot method of hexbin.
Provides a legend indicating the count representations.
grid.hexlegend(legend, ysize, lcex, inner, style = ,
minarea = 0.05, maxarea = 0.8, mincnt = 1, maxcnt, trans = NULL,
inv = NULL, colorcut, density = NULL, border = NULL, pen = NULL,
colramp = function(n) { LinGray(n,beg = 90,end = 15) },
leg.unit = "native")positive number giving width of the legend in inches.
height of legend in inches
the characters expansion size for the text in the legend,
see par(cex=).
the inner diameter of a hexagon in inches.
the hexagon style; see grid.hexagons.
fraction of the cell area for the lowest and largest count, respectively.
minimum and maximum count accepted in plot.
a transformation function for the counts such as
sqrt.
the inverse transformation function.
numeric vector of values covering [0, 1] the determine hexagon color classes boundaries and hexagon legend size boundaries.
argument for polygon(). Draw the border
for each hexagon.
argument for polygon() filling. A
0 causes the polygon not to be filled.
color argument used for polygon(col = .).
Determines the color with which the polygon will be filled.
function accepting an integer n as an argument and
returning n colors.
unit to use
The plot method for hexbin objects calls this function
to produce a legend
by setting the graphics parameters, so hex.legend itself is not a
standalone function.
The legend function is preliminary. Later version will include refinements and handle extreme cases (small and large) for cell size and counts.
See the Details section of grid.hexagons's help page.
This function does not return any value.
see in grid.hexagons.
## Not a stand alone function; typically only called from plot.hexbin()
