orthogram 189
orthogram
Orthonormal decomposition of variance
Description
This function performs the orthonormal decomposition of variance of a quantitative variable on an
orthonormal basis. It also returns the results of five non parametric tests associated to the variance
decomposition. It thus provides tools (graphical displays and test) for analysing phylogenetic,
spatial and temporal pattern of one quantitative variable.
Usage
orthogram(x, orthobas = NULL, neig = NULL, phylog = NULL,
nrepet = 999, posinega = 0, tol = 1e-07, na.action = c("fail",
"mean"), cdot = 1.5, cfont.main = 1.5, lwd = 2, nclass,
high.scores = 0,alter=c("greater", "less", "two-sided"))
Arguments
x

neig
phylog

posinega
tol
na.action
cdot
cfont.main
lwd
nclass
high.scores
alter
a numeric vector corresponding to the quantitative variable
an object of class ’orthobasis’
an object of class ’neig’
an object of class ’phylog’
an integer giving the number of permutations
a parameter for the ratio test. If posinega > 0, the function computes the ratio
test.
a tolerance threshold for orthonormality condition
if ’fail’ stops the execution of the current expression when z contains any missing
value. If ’mean’ replaces any missing values by mean(z)
a character size for points on the cumulative decomposition display
a character size for titles
a character size for dash lines
a single number giving the number of cells for the histogram
a single number giving the number of vectors to return. If > 0, the function
returns labels of vectors that explains the larger part of variance.
a character string specifying the alternative hypothesis, must be one of "greater"
(default), "less" or "two-sided"
