An object of class "treemodel" returned by
pls.treemodel.
comp.by
One of "nodes" or "latents". This argument indicates the type
of barplots comparison.
nodes.names
Optional vector of names for the terminal nodes (must be a
vector of length equal to the number of terminal nodes).
ordered
A logical value indicating whether the barplots are shown in
increasing ordered.
decreasing
A logical value indicating if the sort order should be
increasing or decreasing.
color
Optional vector of colors for the bars. When color=NULL
rainbow colors are used.
show.box
A logical value indicating whether a box is drawn around each
barplot.
border
The color to be used for the border of the bars. Use
border=NA to omit borders.
cex.names
Expansion factor for axis names (bar labels).
cex.axis
Expansion factor for numeric axis labels.
short.labs
Logical value indicating if the labels of the barplots
should be abbreviated (TRUE by default).
short.min
Integer number indicating the minimum length of the
abbreviations for the labels. Only used when short.labs=TRUE.
cex.main
Allows to fix the size of the main. Equal to 1 to default
...
Further arguments are ignored.
Details
This function aims to visualize the comparison between path coefficients of
the terminal nodes against the path coefficients of the global model in the
root node. When comp.by="nodes" a graphic window is displayed for
each endogenous latent variable of the PLS model, and barplots of nodes are
shown. When comp.by="latents" a graphic window is displayed for
each endogenous relationship of the PLS model, and barplots of independent
latent variables are shown.
