suns: Plot Suns

In StatDA: Statistical Analysis for Environmental Data

Plot Suns

Description

This function makes a graphical diagram of multivariate data. Every element represents one line in the sun and the length of the line indicates the concentration of the element.

Usage

suns(x, full = TRUE, scale = TRUE, radius = TRUE, labels = dimnames(x)[[1]],
locations = NULL, nrow = NULL, ncol = NULL, len = 1, key.loc = NULL,
key.labels = dimnames(x)[[2]], key.xpd = TRUE, xlim = NULL, ylim = NULL,
flip.labels = NULL, col.stars = NA, axes = FALSE, frame.plot = axes, main = NULL,
sub = NULL, xlab = "", ylab = "", cex = 0.8, lwd = 0.25, lty = par("lty"),
xpd = FALSE,
mar = pmin(par("mar"), 1.1 + c(2 * axes + (xlab != ""), 2 * axes + (ylab != ""), 1, 0)),
add = FALSE, plot = TRUE, ...)

Arguments

x	a matrix or a data frame
full	if TRUE, a whole circle will be made
scale	if TRUE, the data will be scaled
radius	should be TRUE, otherwise the lines in the sun will not be plotted
labels	the labels for the suns inside the map
locations	the locations for the suns inside the map
nrow, ncol	integers giving the number of rows and columns to use when locations=NULL
len	scaling factor for the length of the lines (according to the size of the map)
key.loc	the location for the legend
key.labels	the labels in the legend
key.xpd	A logical value or NA. If FALSE, all plotting is clipped to the plot region, if TRUE, all plotting is clipped to the figure region, and if NA, all plotting is clipped to the device region.
flip.labels	logical indication if the label locations should flip up and down from diagram to diagram.
axes	if FALSE, no axes will be drawn
frame.plot	if TRUE, a box will be made around the plot
main, sub, xlab, xlim, ylim, col.stars, ylab, cex, lwd, lty, xpd, mar	graphical parameters and labels for the plot
add	if TRUE, it will be added to the plot
plot	nothing is plotted
...	graphical parameters for plotting the box

Details

Each sun represents one row of the input x. Each line of the sun represents one choosen element. The distance from the center of the sun to the point shows the size of the value of the (scaled) column.

Value

No return value, creates a plot.
