| \title{Simple Panel Plot} |
| \description{ |
| An example of a simple useful \code{panel} function to be used as |
| argument in e.g., \code{\link{coplot}} or \code{\link{pairs}}. |
| } |
| \usage{ |
| panel.smooth(x, y, col = par("col"), bg = NA, pch = par("pch"), |
| cex = 1, col.smooth = "red", span = 2/3, iter = 3, |
| \dots) |
| } |
| \arguments{ |
| \item{x, y}{numeric vectors of the same length} |
| \item{col, bg, pch, cex}{numeric or character codes for the color(s), |
| point type and size of \code{\link{points}}; see also |
| \code{\link{par}}.} |
| \item{col.smooth}{color to be used by \code{lines} for drawing the |
| smooths.} |
| \item{span}{smoothing parameter \code{f} for \code{\link{lowess}}, see |
| there.} |
| \item{iter}{number of robustness iterations for \code{\link{lowess}}.} |
| \item{\dots}{further arguments to \code{\link{lines}}.} |
| } |
| \seealso{ |
| \code{\link{coplot}} and \code{\link{pairs}} where \code{panel.smooth} |
| is typically used; |
| \code{\link{lowess}} which does the smoothing. |
| } |
| \examples{ |
| pairs(swiss, panel = panel.smooth, pch = ".") # emphasize the smooths |
| pairs(swiss, panel = panel.smooth, lwd = 2, cex = 1.5, col = "blue") # hmm... |
