##### Plot a Function Array

Plots an array of summary functions, usually associated with a point pattern, stored in an object of class "fasp". A method for plot.

Keywords
spatial
##### Usage
plot(x)
plot(x, formula=formula)
plot(x, formula=formula, subset)
plot(x, formula=formula, subset, lty, col, title, ...)
##### Arguments
x
An object of class "fasp" representing a function array.
formula
A formula or list of formulae indicating what variables are to be plotted against what variable. If formula is a list, its $k^{th}$ component should be applicable to the $(i,j)^{th}$ plot where x$which[i,j]=k. I subset A logical vector, or a vector of indices, or an expression or a character string, or a list of such, indicating a subset of the data to be included in each plot. If subset is a list, its$k^{th}$component should be lty A vector of integers indicating line types to be used in forming the plot. col A vector of integers indicating colours for the different lines which form the plot. title Overall title for the plot. ... Arguments passed to plot.default to control other features of the individual plot panels. ##### Details An object of class "fasp" represents an array of summary functions, usually associated with a point pattern. See fasp.object for details. Such an object might be created, for example, by alltypes or allstats. The function plot.fasp is a method for plot. It calls plot.fv to plot the individual panels. For information about the interpretation of the arguments formula, subset, lty and col, see plot.fv. The argument title, if present, will determine the overall title of the plot. If it is absent, it defaults to x$title. Titles for the individual plot panels will be taken from x$titles. ##### Value • None. ##### synopsis plot.fasp(x,formula=NULL,subset=NULL,lty=NULL,col=NULL,title=NULL,...) ##### Warnings (Each component of) the subset argument may be a logical vector (of the same length as the vectors of data which are extracted from x), or a vector of indices, or an expression such as expression(r<=0.2)< code="">, or a text string, such as "r<=0.2"< code="">. Attempting a syntax such as subset = r<=0.2< code=""> (without wrapping r<=0.2< code=""> either in quote marks or in expression()) will cause this function to fall over. Variables referred to in any formula must exist in the data frames stored in x. What the names of these variables are will of course depend upon the nature of x. ##### See Also ##### Aliases • plot.fasp • plot ##### Examples # Bramble Canes data. data(bramblecanes) X.G <- alltypes(bramblecanes,type="G",dataname="Bramblecanes",verb=TRUE) plot(X.G) plot(X.G,subset="r<=0.2") plot(X.G,formula=cbind(asin(sqrt(km)), asin(sqrt(theo))) ~ asin(sqrt(theo))) plot(X.G,fo=cbind(km-theo,0)~r,"r<=0.2") # Swedish pines. data(swedishpines) X <- allstats(swedishpines,dataname="Swedish Pines") plot(X,subset=list("r<=20","r<=20","r<=20","r<=50")) # Simulated data. pp <- runifpoint(350, owin(c(0,1),c(0,1))) pp$marks <- factor(c(rep(1,50),rep(2,100),rep(3,200)))
