overriding axis limits in hexbin plot?
...ackage help,
vignette ...)
It seems fairly hard (without some fairly serious hacking) to
hard-code the axis limits in a hexbin plot from the hexbin package.
Here's what I've figured out so far:
* when you do the hexagonal binning in the first place, you can
specify the x and y ranges (xbnds, ybnds). Fine ... but ...
* the plot method for 'hexbin' objects (which doesn't have 'xlim' or
'ylim' arguments) calls hexViewport as
hexViewport(x, offset = unit(legend, "inches"))
* in the absence of explicit 'xbnds'/'ybnds' argument...

limit ranges in hexbin
...'numeric'))
x<-unlist(data[1])
y<-unlist(data[2])
hbin<-hexbin(x, y)
plot(hbin)
That does get me a hexgonal bin plot, so far, so good. My problem now is
twofold:
1) Some of my data points have really high values in x and y, and I would like
to exclude them. First idea was to set xbnds and ybnds parameters for hexbin
like this.
hbin<-hexbin(x, y, xbins = 50, xbnds = c(0, 5000))
However, hexbin does not like it: Error in hexbin(x, y, xbins = 50, xbnds =
c(0, 5000)) : 'xbnds' must encompass range(x). Is there some other way to
enforce limits in x and y? Otherwise, I...
