| \title{Draw a Boxplot for each Column (Row) of a Matrix} |
| \description{ |
| Interpreting the columns (or rows) of a matrix as different groups, draw a |
| boxplot for each. |
| } |
| \usage{ |
| \method{boxplot}{matrix}(x, use.cols = TRUE, \dots) |
| } |
| \arguments{ |
| \item{x}{a numeric matrix.} |
| \item{use.cols}{logical indicating if columns (by default) or rows |
| (\code{use.cols = FALSE}) should be plotted.} |
| \item{\dots}{Further arguments to \code{\link{boxplot}}.} |
| } |
| \value{ |
| A list as for \code{\link{boxplot}}. |

| \examples{ |
| ## Very similar to the example in ?boxplot |
| mat <- cbind(Uni05 = (1:100)/21, Norm = rnorm(100), |
| T5 = rt(100, df = 5), Gam2 = rgamma(100, shape = 2)) |
| boxplot(mat, main = "boxplot.matrix(...., main = ...)", |
| notch = TRUE, col = 1:4) |
