hex3d.plot {hexbin}R Documentation

A 3D version of plot.hexbin - EXPERIMENTAL

Description

A 3D-version of plot.hexbin but experimental.

Usage

hex3d.plot(x, inner = 0.7, style = c("colorscale", "centroids", "lattice"),
           legend = 1, lcex = 1,
           minarea = 0.04, maxarea = 0.8, mincnt = 1, maxcnt = max(x$cnt),
           trans = NULL, inv = NULL,
           colorcut = seq(0, 1, length = min(17, maxcnt)),
           tilt = 0, tilt.dir = 0, lt.angle = 145,
           lt.azimuth = 30, peak = NULL, pen = NULL,
           border.base = NULL, border.top = NULL, border.side = NULL,
           colramp = function(n) { LinGray(n, beg = 90, end = 15) },
           xlab = "", ylab = "", verbose = getOption("verbose"), ...)

Arguments

x an object of class hexbin.
inner ........ fraction .........
style string, one of ("colorscale", "lattice", "centroids" ), see hexagons.3d.
legend width of the legend in inches. If False or 0 the legend is not produced.
lcex characters expansion size for the text in the legend
minarea fraction of cell area for the lowest count
maxarea fraction of the cell area for the largest count
mincnt cells with fewer counts are ignored.
maxcnt cells with more counts are ignored.
trans function specifying a transformation for the counts such as sqrt.
inv the inverse transformation of trans.
colorcut vector of values covering [0, 1] that determine hexagon color class boundaries and hexagon legend size boundaries.
tilt ~~Describe tilt here~~
tilt.dir ~~Describe tilt.dir here~~
lt.angle ~~Describe lt.angle here~~
lt.azimuth ~~Describe lt.azimuth here~~
peak ~~Describe peak here~~
pen Polygon() col argument. Determines the color with which the polygon will be filled
border.base ~~Describe border.base here~~
border.top ~~Describe border.top here~~
border.side ~~Describe border.side here~~
colramp function accepting an integer n as an argument and returning n colors.
xlab xlabel argument to plot().
ylab ylabel argument to plot().
verbose logical indicating if some diagnostic output should happen.
... additional arguments from and passed to plot methods.

Value

invisible(par)

Examples

## 1) simple binning of spherical normal:
x <- rnorm(10000)
y <- rnorm(10000)
bin <- hexbin(x,y)

# basic plot
hex3d.plot(bin)
# lattice (not really nicely 3D)
hex3d.plot(bin, style= "lattice")

# controlling the colorscheme
hex3d.plot(bin, colramp=BTY, colorcut=c(0:4,6,10)/10)

## 2) A mixture distribution
x <- c(rnorm(5000),rnorm(5000,4,1.5))
y <- c(rnorm(5000),rnorm(5000,2,3))
bin <- hexbin(x,y)

## UNFINISHED -- and FIXME : this gives warnings:
pens <- cbind(c("#ECE2F0","#A6BDDB","#1C9099"),
              c("#FFF7BC","#FEC44F","#D95F0E"))
hex3d.plot(bin, style = "lattice", pen=pens)

# lower resolution binning and overplotting with counts
bin <- hexbin(x,y,xbins=25)
oldpar <- par(no.readonly=TRUE)
scrPar <- hex3d.plot(bin, style= "lattice",legend=FALSE,
                      minarea=1,maxarea=1, border.base="white")
par(scrPar) # reset graphics to the plot on the screen
xy <- hcell2xy(bin)
text(xy$x,xy$y,as.character(bin$cnt),adj=.5, cex=.75, col="blue")
points(x,y,pch=".",col="red") # to show points rather than counts
par(oldpar) # reset graphics

# Be creative, have fun!
