ggplot methods to plot dbmss objects

Description

S3 methods for the autoplot generic.

Usage

  ## S3 method for class 'envelope'
autoplot(object, fmla, ..., ObsColor = "black", 
        H0Color = "red", ShadeColor = "grey75", alpha = 0.3, main = NULL, 
        xlab = NULL, ylab = NULL, LegendLabels = NULL)
  ## S3 method for class 'fv'
autoplot(object, fmla, ..., ObsColor = "black", 
        H0Color = "red", ShadeColor = "grey75", alpha = 0.3, main = NULL, 
        xlab = NULL, ylab = NULL, LegendLabels = NULL)
  ## S3 method for class 'wmppp'
autoplot(object, ..., show.window = TRUE, 
        MaxPointTypes = 6, Other = "Other",
        main = NULL, xlab = NULL, ylab = NULL, LegendLabels = NULL, 
        labelSize = "Weight", labelColor = "Type", palette="Set1",
        windowColor = "black", windowFill = "transparent", alpha = 1)

Arguments

object	An object to be plotted.
fmla	An R language formula determining which variables or expressions are plotted. Either a formula object, or a string that can be parsed as a formula. See plot.fv.
...	Extra arguments, currently unused.
ObsColor	The color of the line representing observed values of the function.
H0Color	The color of the line representing the null hypothesis values of the function.
ShadeColor	The color of the confidence envelope.
alpha	The opacity of the confidence envelope (in function values) or the points (in maps), between 0 and 1.
main	The title of the plot.
xlab, ylab	The axes labels.
LegendLabels	A vector of characters. The first two items describe the observed and null-hypothesis curves, the third and last item the confidence interval. To be used only in plots with two curves (typically observed and expected values). The default is 'NULL' to display the full description of functions.
show.window	if 'TRUE', the borders of the window containing the points are shown on the point map.
MaxPointTypes	The maximum number of different point types to show. If the point set contains more of them, the less frequent ones are gathered as "Other". This number must be limited for readability and not to exceed the number of colors offered by the palette.
Other	The name of the point types gathered as "Other".
labelSize	The guide of the point size legend in point maps, i.e. what the 'PointSize' mark represents.
labelColor	The guide of the point color legend in point maps, i.e. what the 'PointType' mark represents.
palette	The color palette used to display point types in maps. See scale_colour_brewer
windowColor	The color used to draw the limits of the windows in point maps.
windowFill	The color used to fill the windows in point maps.

Details

Plots of 'wmppp' objects are a single representation of both point types and point weights. Rectangular and polygonal windows (see owin.object) are supported but mask windows are ignored (use the 'plot' method if necessary).

Value

A ggplot object.

Examples

data(paracou16)
# Keep only 20% of points to run this example
X <- as.wmppp(rthin(paracou16, 0.2))
autoplot(X)

# Plot the envelope (should be 1000 simulations, reduced to 20 to save time)
autoplot(KdEnvelope(X, ReferenceType="Q. Rosea", NumberOfSimulations=20))

# With a formula and a compact legend
autoplot(KEnvelope(X, NumberOfSimulations=20), 
    ./(pi*r^2) ~ r,
    LegendLabels=c("Observed", "Expected", "Confidence\n enveloppe"))
