hexbinFull {hexDensity} | R Documentation |
Hexagonal binning with whole grid output.
Description
Adapted from hexbin to output hexagons with 0 count, and also to allow points with different weights. Default to use regular hexagon. See hexbin for extra detail on the output.
Usage
hexbinFull(
x,
y = NULL,
xbins = 128,
shape = NULL,
xbnds = range(x),
ybnds = range(y),
xlab = NULL,
ylab = NULL,
IDs = FALSE,
weight = NULL
)
Arguments
x , y |
Coords of the points or a single plotting structure to be used in binning. See xy.coords. |
xbins |
Number of bins in a row. |
shape |
shape = yheight/xwidth of the plotting regions |
xbnds , ybnds |
Horizontal and vertical limits of the binning region in x or y units respectively, must encompass range(x) or range(y) respectively; Vector of length 2 |
xlab , ylab |
Optional character strings used as labels for x and y. If NULL, sensible defaults are used. |
IDs |
Logical indicating if the hexagonal cell ID for each point should be returned, see hexbin. |
weight |
Numeric weight vector to be assigned to points. |
Value
an S4 object of class hexbin.
