Paul Tol's Diverging Color Schemes for ggplot2 and ggraph
Description
Provides diverging color scales from Paul Tol's Colour Schemes.
Arguments

Details
Palette | Max. colors | NA value |
sunset | 11 | #FFFFFF |
BuRd | 9 | #FFEE99 |
PRGn | 9 | #FFEE99 |
Value
A continuous scale.
Interpolation
If more colors than defined are needed from a given scheme, the color coordinates are linearly interpolated to provide a continuous version of the scheme.
Note that the default color for NA
can be overridden by passing
a value to ggplot2::continuous_scale()
.
