compositions (version 1.01-1)

pairwiseplot: Creates a paneled plot like pairs for two different datasets.

Description

Creates a plot for each element of two lists or each column of each dataset against each of the second.

Usage

pairwisePlot(X,Y,...)
## S3 method for class 'default':
pairwisePlot(X,Y=X,...,xlab=deparse(substitute(X)),ylab=deparse(substitute(Y)),nm=c(length(Y),length(X)),panel=plot)

Arguments

X

a list, a data.frame, or a matrix representing the first set of things to be displayed.

Y

a list, a data.frame, or a matrix representing the second set of things to be displayed.

...

furter parameters to the panel function

xlab

The sequence of labels for the elements of X. Alternatively the labels can be given as colnames or names of X. This option takes precedence if specified.

ylab

The sequence of labels for the elements of Y. Alternatively the labels can be given as colnames or names of Y. This option takes precedence if specified.

nm

the parameter to be used in the call par(mfrow=nm). If NULL no parameter is setted and a sequence of plots can be generated.

panel

The panel function to plot the individual panels. it is called as panel(x,y,xlab=xlab,ylab=ylab,...). Thus the panel function must be capable of of taking these arguments. It must also set up its own plot. There is no negotiation

Details

This is a light weight conveniance function to several aspects of one dataset against several aspects of another dataset. It is far more straight forward than e.g. the pairs function and does not do any internal computation rather than organizing the names.
