Plot a Correlogram

Description

These functions plot correlagrams previously computed with correlogram.formula.

Usage

  ## S3 method for class 'correlogram':
  plot(x, legend = TRUE, test.level = 0.05,
                col = c("grey", "red"), type = "b", xlab = "",
                ylab = "Moran's I", pch = 21, cex = 2, ...)
  ## S3 method for class 'correlogramList':
  plot(x, lattice = TRUE, legend = TRUE,
                test.level = 0.05, col = c("grey", "red"),
                xlab = "", ylab = "Moran's I",
                type = "b", pch = 21, cex = 2, ...)

Arguments

x an object of class "correlogram" or of class "correlogramList" (both produced by correlogram.formula).
legend should a legend be added on the plot?
test.level the level used to discriminate the plotting symbols with colours considering the P-values.
col two colours for the plotting symbols: the first one is used if the P-value is greater than or equal to test.level, the second one otherwise.
type the type of plot to produce (see plot for possible choices).
xlab an optional character string for the label on the x-axis (none by default).
ylab the default label on the y-axis.
pch the type of plotting symbol.
cex the default size for the plotting symbols.
lattice when plotting several correlograms, should they be plotted in trellis-style with lattice (the default), or together on the same plot?
... other parameters passed to the plot or lines function.

Details

When plotting several correlograms with lattice, some options have no effect: legend, type, and pch (pch=19 is always used in this situation).

When using pch between 1 and 20 (i.e., non-filled symbols, the colours specified in col are also used for the lines joining the points. To keep black lines, it is better to leave pch between 21 and 25.
