This functions implements a scatterplot method for
factor
arguments of the generic
plot
function.
If y
is missing barplot
is produced.
For numeric y
a boxplot
is used, and for a factor
y
a spineplot
is shown. For any other type of
y
the next plot
method is called, normally
plot.default
.
# S3 method for factor
plot(x, y, legend.text = NULL, …)
numeric or factor. y
may be missing.
character vector for annotation of y axis in the
case of a factor y
: defaults to levels(y)
. This
sets the yaxlabels
argument of spineplot
.

plot(cut(weight, 2) ~ group, data = PlantGrowth) # factor ~ factor
## passing "..." to spineplot() eventually:
plot(cut(weight, 3) ~ group, data = PlantGrowth,
col = hcl(c(0, 120, 240), 50, 70))
plot(PlantGrowth$group, axes = FALSE, main = "no axes") # extremely silly
