plotstruct {phyclust}

Struct Plots of Observations Based on Posterior Probabilities

Description

This function provides structure plots of data set given based on posterior probabilities, the Z.normalized matrix.

Usage

plotstruct(Z, X.class = NULL, sort.inside.class = TRUE,
    direction = "h", main = "Structure Plot", xlab = "Observations",
    ylab = "Posterior Probabilities", ...)

Arguments

Z

a Z matrix as Z.normalized in Class phyclust.

X.class

class ids indicated for all observations

sort.inside.class

sort observations inside class by max posteriors.

direction

either "h" for horizontal or "v" for vertical.

main

main label, default = "Structure Plot".

xlab

x-axis label, default = "Observations".

ylab

y-axis label, default = "Posterior Probabilities".

...

other options passed to plot.

Details

The posterior probabilities in ret.phyclust$Z.normalized will be drawn in colors.

If X.class is submitted, the plot will draw in the order of class ids and the sort.inside.class will be skipped.

Value

A structure plot will be drawn.

Examples

## Not run: 
library(phyclust, quiet = TRUE)

set.seed(1234)
ret.1 <- phyclust(seq.data.toy$org, 3)
plotstruct(ret.1$Z.normalized)
windows()
plotstruct(ret.1$Z.normalized, sort.inside.class = FALSE)

# With class ids
X.class <- as.numeric(gsub(".*-(.*)", "\\1", seq.data.toy$seqname))
windows()
plotstruct(ret.1$Z.normalized, X.class = X.class)
