- facets
A set of variables or expressions quoted by vars()
and defining faceting groups on the rows or columns dimension.
The variables can be named (the names are passed to labeller).
For compatibility with the classic interface, can also be a
formula or character vector. Use either a one sided formula, ~a + b,
or a character vector, c("a", "b").
- scales
Should scales be fixed ("fixed", the default),
free ("free"), or free in one dimension ("free_x",
"free_y")?
- space
Should the size of the panels be fixed or relative to the range
of the respective position scales
- shrink
If TRUE, will shrink scales to fit output of
statistics, not raw data. If FALSE, will be range of raw data
before statistical summary.
- labeller
A function that takes one data frame of labels and
returns a list or data frame of character vectors. Each input
column corresponds to one factor. Thus there will be more than
one with vars(cyl, am). Each output
column gets displayed as one separate line in the strip
label. This function should inherit from the "labeller" S3 class
for compatibility with labeller(). You can use different labeling
functions for different kind of labels, for example use label_parsed() for
formatting facet labels. label_value() is used by default,
check it for more details and pointers to other options.
- drop
If TRUE, the default, all factor levels not used in the
data will automatically be dropped. If FALSE, all factor levels
will be shown, regardless of whether or not they appear in the data.
- strip.position
By default, the labels are displayed on the top of
the plot. Using strip.position it is possible to place the labels on
either of the four sides by setting strip.position = c("top",
"bottom", "left", "right")
