| \title{Plot Method for Data Frames} |
| \description{ |
| \code{plot.data.frame}, a method for the \code{\link{plot}} generic. |
| It is designed for a quick look at numeric data frames. |
| } |
| \usage{ |
| \method{plot}{data.frame}(x, \dots) |
| } |
| \arguments{ |
| \item{x}{object of class \code{data.frame}.} |
| \item{\dots}{further arguments to \code{\link{stripchart}}, |
| \code{\link{plot.default}} or \code{\link{pairs}}.} |
| } |
| \details{ |
| This is intended for data frames with \emph{numeric} columns. For more |
| than two columns it first calls \code{\link{data.matrix}} to convert |
| the data frame to a numeric matrix and then calls \code{\link{pairs}} |
| to produce a scatterplot matrix. This can fail and may well be |
| inappropriate: for example numerical conversion of dates will lose |
| their special meaning and a warning will be given. |
| |
| For a two-column data frame it plots the second column against the |
| first by the most appropriate method for the first column. |
| |
| For a single numeric column it uses \code{\link{stripchart}}, and for |
| other single-column data frames tries to find a plot method for the |
| single column. |
