Bivariate time series plots: scatterplots, directed lines and kernel density
estimations using functions in the sm package.
Usage
autopairs(x, lag = 1, h, type = c("levels", "persp", "image", "lines",
"points", "regression"))
Arguments
x
time series
lag
time lag
h
kernel window (useful only for kernel estimations)
type
type of plot: contour levels, perspective plots, image, directed
lines, points or points with superposed kernel regression
Value
None. Plots are produced on the default graphical device.
Details
Bivariate time series plots: scatterplots, directed lines and kernel density
and regression functions estimations using functions in the package sm.
In particular, for kernel density estimation sm.density is
used, with smoothing parameter h defaulting to
hnorm. For kernel regression,
sm.regression is used.

For finer control on density estimation, consider using directly
sm.density and, especially, sm.ts.pdf
from package sm.
