kdepairs: Scatterplot Matrix with 2D Kernel Density
Description
Scatterplot matrix with 2D kernel density.
Usage
kdepairs(x, ...)
# S3 method for default
kdepairs(x, n=25, density=TRUE, contour=TRUE, ...)
# S3 method for rsf
kdepairs(x, n=25, density=TRUE, contour=TRUE, ...)
Value
Produces a scatterplot matrix with histograms in diagonal, 2D kernel
density estimates and contours in the lower half and bivariate scatterplots
with lowess smooth curves and Pearson correlation values
in the upper half as a side effect.
Returns NULL invisibly.
Arguments
x
a matrix or data frame (or a fitted model object of class "rsf"
or "rspf").
n
number of bins to be used in kernel density estimation.
density
logical, if shades corresponding to densities should be plotted.
contour
logical, if contour on top of shades should be plotted.
