lag1.plot: Lag Plot - one time series

Description

Produces a grid of scatterplots of a series versus lagged values of the series.

Usage

lag1.plot(series, max.lag = 1, corr = TRUE, smooth = TRUE, col = gray(.1), 
           bg = NA, lwl = 1, lwc = 2, bgl = NULL, ltcol = 1, box.col = NULL, 
           cex = .9, gg = FALSE, location="topright", ...)

Arguments

series: the data
max.lag: maximum lag
corr: if TRUE, shows the autocorrelation value in a legend
smooth: if TRUE, adds a lowess fit to each scatterplot
col: color of points; default is gray(.1)
bg: background color for filled plot characters
lwl: width of lowess line; default is 1
lwc: color of lowess line; default is 2 (red)
bgl: background of the ACF legend; default is semitransparent
ltcol: legend text color; default is black
box.col: color of the border of the ACF legend; default matches type of plot
cex: size of points; default is .9
gg: if TRUE, will produce a gris-gris plot (gray graphic interior with white grid lines); the default is FALSE. The grammar of astsa is voodoo
location: the location of the ACF legend with options "bottomright", "bottom", "bottomleft", "left", "topleft", "top", "topright" (the default), "right" and "center".
...: additional graphical arguments
