Default line types based on a set supplied by Richard Pearson,
University of Manchester. Continuous values can not be mapped to
line types.
scale_linetype(..., na.value = "blank")
scale_linetype_continuous(...)
scale_linetype_discrete(..., na.value = "blank")
Arguments
... |
Arguments passed on to discrete_scale
- breaks
One of:
NULL for no breaks
waiver() for the default breaks computed by the
transformation object
A character vector of breaks
A function that takes the limits as input and returns breaks
as output
- limits
A character vector that defines possible values of the scale
and their order.
- drop
Should unused factor levels be omitted from the scale?
The default, TRUE , uses the levels that appear in the data;
FALSE uses all the levels in the factor.
- na.translate
Unlike continuous scales, discrete scales can easily show
missing values, and do so by default. If you want to remove missing values
from a discrete scale, specify na.translate = FALSE .
- aesthetics
The names of the aesthetics that this scale works with
- scale_name
The name of the scale
- palette
A palette function that when called with a single integer
argument (the number of levels in the scale) returns the values that
they should take
- name
The name of the scale. Used as axis or legend title. If
waiver() , the default, the name of the scale is taken from the first
mapping used for that aesthetic. If NULL , the legend title will be
omitted.
- labels
One of:
NULL for no labels
waiver() for the default labels computed by the
transformation object
A character vector giving labels (must be same length as breaks )
A function that takes the breaks as input and returns labels
as output
- guide
A function used to create a guide or its name. See
guides() for more info.
- super
The super class to use for the constructed scale
|
na.value |
The linetype to use for NA values. |
