classscatter

Classification scatterplot matrix

Function to plot a scatterplot matrix with a classification result.

classscatter(formula, data, method, col.correct = "black", 
    col.wrong = "red", gs = NULL, ...)

`formula`	formula of the form `groups ~ x1 + x2 + ...`. That is, the response is the grouping factor and the right hand side specifies the (non-factor) discriminators.
`data`	Data frame from which variables specified in formula are preferentially to be taken.
`method`	character, name of classification function (e.g. “`lda`”).
`col.correct`	color to use for correct classified objects.
`col.wrong`	color to use for missclassified objects.
`gs`	group symbol (plot character), must have the same length as the data. If `NULL`, `as.character(groups)` is the default.
`...`	further arguments passed to the underlying classification method or plot functions.

The actual error rate.
