scale_radius_continuous {ggfields} | R Documentation |
Vector field radius scales
Description
Scales to set up the visualisation of the radius
aesthetic. These
scales are also automatically used in plot guides.
Note that scale_radius_identity()
does not exist as it would be impossible to
relate such a scale to the max_radius
parameter. For more details see
vignette("radius_aes")
.
Usage
scale_radius_continuous(..., range = c(1e-08, 1))
scale_radius_binned(..., range = c(1e-08, 1))
scale_radius_discrete(..., range = c(1e-08, 1))
Arguments
... |
Arguments passed on to underpinning |
range |
Relative output range of radii. Must lie between 0 and 1. |
Value
An object of class Scale.
