In plotrix/plotrix: Various Plotting Functions

Display a matrix of values as the widths of stacked rectangles

Description

‘⁠battleship.plot⁠’ displays a matrix of rectangles, with widths proportional to the values in ‘⁠x⁠’. The values are scaled so that half the width of the largest rectangle is equal to ‘⁠maxxspan⁠’ in user units. This prevents the rectangles from overlapping. The user can adjust the spacing of the stacks of rectangles by changing ‘⁠maxxspan⁠’. Similarly, maxyspan controls the spacing between rectangles in the vertical direction.

The labels for each stack of plots (the columns of x) are displayed at the top of the plot, angled at 45 degrees. The labels for each row of rectangles in the stacks (the rows of x) are displayed at the left. Long labels for either may require adjusting the ‘⁠mar⁠’ argument.

The function will try to extract the labels ‘⁠xaxlab⁠’ and ‘⁠yaxlab⁠’ from the matrix column and row names respectively if none are passed.

Usage

 battleship.plot(x,mar=c(2,5,5,1),col="white",border="black",
 main="",xlab="",ylab="",xaxlab=NULL,yaxlab=NULL,cex.labels=1,
 maxxspan=0.45,maxyspan=0.45)

Arguments

x	A matrix or data frame containing numeric values. See the example.
mar	Margins for the plot.
col	The fill colors for the rectangles.
border	The border colors for the rectangles.
main	The title for the plot (i.e. ‘⁠main⁠’).
xlab,ylab	The x and y axis labels.
xaxlab,yaxlab	Optional labels for the rows and columns.
cex.labels	Character expansion for the row and column labels.
maxxspan,maxyspan	Scaling factor for the widths and heights of the rectangles so that they don't overlap.

Value

nil
