coplotTri {GCDkit}R Documentation

Coplot for three variables

Description

Plots a series of binary plots split into several groups according to the values of the third, so called conditioning, variable.

Usage

coplotTri(xaxis = "", yaxis = "", zaxis = "", int = "")

Arguments

xaxis

Name of the data column to be used as x axis.

yaxis

Name of the data column to be used as y axis.

zaxis

Name of the data column with the conditioning variable.

int

The specification of the intervals: either 'auto' or a list of break points separated by commas.

Details

For examination of large datasets split into user-defined subsets serves in R the function 'coplot'. It displays a series of binary diagrams with the data filtered out according to the values of the third (conditioning) variable.

If no parameters 'xlab', 'ylab' and 'zlab' are given, the user is prompted to specify them.

The variables to be plotted are selected using the function 'selectColumnLabel.

After this is done, the user is prompted to enter a comma-delimited list of at least one break point defining the intervals. The default includes the mean, that will be automatically supplemented by minimum and maximum (i.e. two intervals).

See manual entry for 'coplot' for further details.

Value

None.

Please note that no formulae can be handled at this stage.

Examples

coplotTri("SiO2","Na2O","MgO","auto")

coplotTri("MgO","Na2O","SiO2","50,60") 
# the intervals of the conditioning variable, SiO2, 
# will be (min(SiO2) - 50),(50 - 60) and (60 - max(SiO2))
