autopairs {tsDyn}

Bivariate time series plots

Description

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

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.

Value

None. Plots are produced on the default graphical device.

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