R: Produce h-scatterplot

hscat {gstat} | R Documentation

## Produce h-scatterplot

### Description

Produces h-scatterplots, where point pairs having specific separation distances are plotted. This function is a wrapper around xyplot.

### Usage

    hscat(formula, data, breaks, pch = 3, cex = .6, mirror = FALSE,
    	variogram.alpha = 0, as.table = TRUE,...)

### Arguments

`formula` | specifies the dependent variable
`data` | data where the variable in formula is resolved
`breaks` | distance class boundaries
`pch` | plotting symbol
`cex` | plotting symbol size
`mirror` | logical; duplicate all points mirrored along x=y? (note that correlations are those of the points plotted)
`variogram.alpha` | parameter to be passed as alpha parameter to variogram; if alpha is specified it will only affect xyplot by being passed through ...
`as.table` | logical; if `TRUE`, panels plot top-to-bottom
`...` | parameters, passed to variogram and xyplot

### Value

an object of class trellis; normally the h scatter plot

### Note

Data pairs are plotted once, so the h-scatterplot are not symmetric.

### Examples

    library(sp)
    data(meuse)
    coordinates(meuse) = ~x+y
    hscat(log(zinc)~1, meuse, c(0, 80, 120, 250, 500, 1000))
