height
|
either a vector or matrix of values describing the bars
which make up the plot. If height is a vector, the plot consists
of a sequence of rectangular bars with heights given by the values in
the vector. If height is a matrix and beside is FALSE
then each bar of the plot corresponds to a column of height , with
the values in the column giving the heights of stacked ``sub-bars''
making up the bar. If height is a matrix and beside is
TRUE , then the values in each column are juxtaposed rather than
stacked.
|
width
|
optional vector of bar widths.
|
space
|
the amount of space (as a fraction of the average bar
width) left before each bar. May be given as a single number or one
number per bar. If height is a matrix and beside is
TRUE , space may be specified by two numbers, where the first
is the space between bars in the same group, and the second the space
between the groups. If not given explicitly, it defaults to c(0,1)
if height is a matrix and beside is TRUE , and to
0.2 otherwise.
|
names.arg
|
a vector of names to be plotted below each bar or group
of bars. If this argument is omitted, then the names are taken from the
names attribute of height if this is a vector, or the column
names of height if this is a matrix.
|
legend.text
|
a vector of text used to construct a legend for the
plot. This is only useful when height is a matrix. In that case
the legend labels should correspond to the rows of height .
|
beside
|
a logical value. If FALSE , the columns of
height are portrayed as stacked bars, and if TRUE the
columns are portrayed as juxtaposed bars.
|
horiz
|
a logical value. If FALSE , the bars are drawn
vertically with the first bar to the left. If TRUE , the bars are
drwan horizontally with the first at the bottom.
|
col
|
a vector of colors for the bars or bar components.
|
border
|
the color to be used for the border of the bars.
|
main
|
an overall title for the plot.
|
xlab
|
a label for the x axis.
|
ylab
|
a label for the y axis.
|
xlim
|
limits for the x axis.
|
ylim
|
limits for the y axis.
|
axes
|
logical. If TRUE , a vertical axis is drawn.
