Description

Plots a tree plot of a level set tree, of a shape tree, or of a tail tree to the graphics window.

Usage

plottree(lst, 
plot=T, data=F, crit=NULL, orderrule="distcenter",
modelabel=TRUE, ptext=0, leimat=NULL, symbo=NULL, 
info=NULL, infolift=0, infopos=0, infochar=NULL,
xmarginleft=0, xmarginright=0, ymargin=0, 
xlim=NULL, ylim=NULL, col="black", col.axis="black", 
linecol=rep("black",length(lst$parent)), 
pch=21, dimen=NULL, yaxt="s", axes=T,
cex=NULL, nodemag=NULL, linemag=1, 
cex.axis = 1, ylab = "", cex.lab = 1, colo = FALSE, paletti = NULL,
lowest = "dens")

Arguments

lst	level set tree; list of vectors. The list contains at least vectors "level", "volume", and "parent". For example, functions "leafsfirst", "profkern" and "profhist" give a level set tree as an output.
plot	T or F; TRUE if we make a plot, otherwise FALSE.
data	T or F; TRUE if we want output to contain some information, for example an ordering for siblings. This option is needed only by other plotting functions of the package, it is not needed by the end user.
crit	d-vector of real numbers; gives a way to control ordering of siblings. The leftmost sibling is the one whose barycenter is furthest away from vector "crit", in the Euclidean distance.
orderrule	lower level paremeter
modelabel	T or F; TRUE if the modes will be labelled. The default is to use labels M1, M2,...
ptext	non-negative real number; amount by which the mode labels will be lifted.
leimat	vector of characters; length of the vector should be equal to the number of modes of the estimate. This option is for the case we do not want the ordering of the labels to be done automatically.
symbo	character; for example "L". The default value for the automatic labelling of the modes is to use M1, M2,... With "symbo" we may switch to L1, L2,..., for example.
info	vector of numbers or characters, whose length is equal to the number of nodes of the level set tree. The elements of "info" will be placed on the right side of the nodes. For example "info" may be generated by "excmas" or we may define "info" to contain the frequencies of the nodes. (Frequencies may be obtained directly from the function "profhist".)
infolift	real number; controls the vertical positioning of the elements of "info".
infopos	real number; controls the horizontal positioning of the elements of "info". Negative "infopos" will move elements of "info" to the right hand side.
infochar	vector of characters whose length is equal to the number of nodes of the level set tree; we may annotate nodes with some infromation
xmarginleft	nonnegative real number; adds more margin on the left hand side. The box around the plot will be moved to the left with the amount "xmarginleft".
xmarginright	nonnegative real number; adds more margin on the right hand side. The box around the plot will be moved to the right with the amount "xmarginright".
ymargin	nonnegative real number; adds more margin on the top of the plot. The box around the plot will be moved up with the amount "ymargin".
xlim	vector of 2 real numbers; gives the limits for the scale of x-axis.
ylim	vector of 2 real numbers; gives the limits for the scale of y-axis.
col	colour for the nodes; for example "black" or "blue".
col.axis	colour for the x and y-axis; for example "black" or "blue".
linecol	colour for the lines joining nodes; for example "black" or "blue".
pch	symbol for the nodes of the tree; integer 19-25; see help(points) for the definitions
dimen	positive integer; number of dimensions of the estimate. If "dimen" is not NULL, then we plot without using the usual ordering of the siblings. This option is used when we do not have barycenters available.
yaxt	axis type, see "par"
axes	T or F
cex	magnification factor for the symbols; see "par"
nodemag	magnification factor for the points
linemag	magnification factor for the lines joining the points
cex.axis	magnification factor for the axis annotation; see "par"
ylab	character; y-axis label (name of the y-variable); for example in a tree plot of a level set tree this could be "level"
cex.lab	magnification factor for the axis labels (names of x and y); see "par"
colo	TRUE or FALSE; if TRUE, nodes and lines joining the nodes will be colored
paletti	a vector of names of colors; these colors will be used to color the nodes and the lines joining the nodes
lowest	character string; if lowest="dens", then y-axis starts at 0

Value

By default a plot is made on the graphics window.
