## S3 method for class 'formula'
wtd.boxplot(formula, weights = NULL, data = NULL, ..., subset, na.action = NULL)
## Default S3 method:
wtd.boxplot(x, weights = NULL, ..., range = 1.5, width = NULL, varwidth = FALSE,
notch = FALSE, outline = TRUE, names, plot = TRUE,
border = par("fg"), col = NULL, log = "",
pars = list(boxwex = 0.8, staplewex = 0.5, outwex = 0.5),
horizontal = FALSE, add = FALSE, at = NULL)
|
formula |
a formula, such as |
weights |
case weights, vector of the same length as the dependent variable in formula or the variable given as arguments) |
data |
a data.frame (or list) from which the variables in
|
subset |
an optional vector specifying a subset of observations to be used for plotting. |
na.action |
a function which indicates what should happen
when the data contain |
x |
for specifying data from which the boxplots are to be
produced. Either a numeric vector, or a single list containing such
vectors. Additional unnamed arguments specify further data
as separate vectors (each corresponding to a component boxplot).
|
... |
For the For the default method, unnamed arguments are additional data
vectors (unless |
range |
this determines how far the plot whiskers extend out
from the box. If |
width |
a vector giving the relative widths of the boxes making up the plot. |
varwidth |
if |
notch |
if |
outline |
if |
names |
group labels which will be printed under each boxplot. Can be a character vector or an expression (see plotmath). |
boxwex |
a scale factor to be applied to all boxes. When there are only a few groups, the appearance of the plot can be improved by making the boxes narrower. |
staplewex |
staple line width expansion, proportional to box width. |
outwex |
outlier line width expansion, proportional to box width. |
plot |
if |
border |
an optional vector of colors for the outlines of the
boxplots. The values in |
col |
if |
log |
character indicating if x or y or both coordinates should be plotted in log scale. |
pars |
a list of (potentially many) more graphical parameters,
e.g., |
horizontal |
logical indicating if the boxplots should be
horizontal; default |
add |
logical, if true add boxplot to current plot. |
at |
numeric vector giving the locations where the boxplots should
be drawn, particularly when |
The generic function wtd.boxplot
currently has a default method
(wtd.boxplot.default
) and a formula interface (wtd.boxplot.formula
).
If multiple groups are supplied either as multiple arguments or via a
formula, parallel boxplots will be plotted, in the order of the
arguments or the order of the levels of the factor (see
factor
).
Missing values are ignored when forming boxplots.
List with the following components:
stats |
a matrix, each column contains the extreme of the lower whisker, the lower hinge, the median, the upper hinge and the extreme of the upper whisker for one group/plot. If all the inputs have the same class attribute, so will this component. |
n |
a vector with the number of observations in each group. |
conf |
a matrix where each column contains the lower and upper extremes of the notch. |
out |
the values of any data points which lie beyond the extremes of the whiskers. |
group |
a vector of the same length as |
names |
a vector of names for the groups. |
