Plot a Boxplot
Description
Plot a single horizontal boxplot, the default is a Tukey boxplot.
Usage
rg.boxplot(xx, xlab = deparse(substitute(xx)), log = FALSE, ifbw = FALSE,
wend = 0.05, xlim = NULL, main = " ", colr = 5, ...)
Arguments
xx |
data |
xlab |
label for the x-axis |
log |
if TRUE, a log-scaled plot and a logtransformation of the data |
ifbw |
if TRUE, a IDEAS style box-and-whisker plot is produced |
wend |
defines the end of the whisker, default is 5% and 95% quantile |
xlim |
setting xlim results in outliers not being plotted as the x-axis is shortened. |
main |
main title of the plot |
colr |
the box is infilled with a yellow ochre; if no colour is required set colr=0 |
... |
further graphical parameters for the plot |
Details
As the x-axis is shortend by setting xlim, however, the statistics used to define the boxplot, or box-and-whisker plot, are still based on the total data set. To plot a truncated data set create a subset first, or use the x[x<some.value] construct in the call.
Value
No return value, creates a plot.
