In jmw86069/venndir: Directional Venn diagrams

Degrees to text adjustment

Description

Degrees to text adjustment

Usage

degrees_to_adj(
  degrees,
  top = 90,
  clockwise = FALSE,
  expand = 0,
  bias_side = 3,
  bias_height = 1,
  plot_ranges = FALSE,
  ...
)

Arguments

degrees	numeric value for angles in degrees
top	numeric value indicating the angle at the top position
clockwise	logical indicating whether the angle increases in clockwise direction
expand	numeric value intended to expand the adjust value. For example expand=0.5 will expand the adjust value 50%.
...	additional arguments are ignored

Details

Utility function to define adj values suitable for text plotting, which arranges text relative to the angle in degrees.

Examples

degrees <- seq(from=1, to=360, by=33);
adjdf <- degrees_to_adj(degrees);
x <- cos(jamba::deg2rad(degrees));
y <- sin(jamba::deg2rad(degrees));
plot(x, y,
   pch=20, asp=1,
   xlim=c(-1.3, 1.3),
   ylim=c(-1.3, 1.3));
for (i in seq_along(degrees)) {
   text(labels=i,
      x=x[i], y=y[i],
      adj=unlist(adjdf[i,]))
}
