# featurePlot

From caret v6.0-86
by Max Kuhn

##### 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

```
# NOT RUN {
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")
# }
```
