Fluctuation diagram

Description

Draws a fluctuation diagram.

Usage

fd(x, ...)
## S3 method for class 'matrix'
fd(x, add = FALSE, vals = FALSE, at.x, at.y, axes = TRUE,
frame.plot = FALSE, main = NULL, sub = NULL, xlab = NULL, ylab = NULL,
zmax = max(x, na.rm = TRUE), xlim, ylim, asp = 1, panel.first = NULL,
panel.last = NULL, ann = par("ann"), col = "grey", border = "black",
...)
## S3 method for class 'table'
fd(x, add = FALSE, vals = FALSE, at.x, at.y, axes = TRUE,
frame.plot = FALSE, main = NULL, sub = NULL, xlab = NULL, ylab = NULL,
zmax = max(x, na.rm = TRUE), xlim, ylim, asp = 1, panel.first = NULL,
panel.last = NULL, ann = par("ann"), col = "grey", border = "black",
...)

Arguments

x	object to draw fluctuation diagram of (most commonly a table)
add	a logical value indicating whether to add to an existing plot (TRUE) or to create a new plot (FALSE).
vals	a logical value indicating whether to draw values into the rectangles (discouraged and unimplemented).
at.x	locations of the colums (by default 1:ncol)
at.y	locations of the rows (by default 1:nrow)
axes	a logical value indicating whether both axes should be drawn on the plot. Use graphical parameter xaxt or yaxt to suppress just one of the axes.
frame.plot	a logical indicating whether a box should be drawn around the plot.
main	a main title for the plot, see also title.
sub	a subtitle for the plot.
xlab	a label for the x axis.
ylab	a label for the y axis.
zmax	value representing the total size of an allocated box.
xlim	the x limits (x1, x2) of the plot. The default is the range of at.x with an additional 0.5 margin of the ends.
ylim	the y limits of the plot.
asp	the y/x aspect ratio, see plot.window.
panel.first	an expression to be evaluated after the plot axes are set up but before any plotting takes place. This can be useful for drawing background grids
panel.last	an expression to be evaluated after plotting has taken place.
ann	see "ann" graphical parameter
col	color of the boxes to be filled with, will be recycled to match the shape of x.
border	color of the box borders - only scalar value is supported at the moment.
...	additional graphical parameters

Value

Returns (invisibly) a data frame describing the sparse representation of the boxes as location and radius.
