Wrapper for Lattice Plotting of Predictor Variables

A shortcut to produce lattice graphs

Keywords
hplot
Usage
featurePlot(x, y, 
            plot = if(is.factor(y)) "strip" else "scatter",
            labels = c("Feature", ""), 
            ...)
Arguments
x
a matrix or data frame of continuous feature/probe/spectra data.
y
a factor indicating class membership.
plot
the type of plot. For classification: box, strip, density, pairs or ellipse. For regression, pairs or scatter
labels
a bad attempt at pre-defined axis labels
...
options passed to lattice calls.
Details

This function ``stacks'' data to get it into a form compatible with lattice and creates the plots

Value

  • An object of class ``trellis''. The `update' method can be used to update components of the object and the `print' method (usually called by default) will plot it on an appropriate plotting device.

Examples
x <- matrix(rnorm(50*5),ncol=5)
y <- factor(rep(c("A", "B"),  25))

trellis.par.set(theme = col.whitebg(), warn = FALSE)
featurePlot(x, y, "ellipse")
featurePlot(x, y, "strip", jitter = TRUE)
featurePlot(x, y, "box")
featurePlot(x, y, "pairs")
