Scales for relative abundance values — scale_x

Continuous scales that (1) always start at 0, (2) always have the same breaks, and (3) expand using a constant rather than a percentage. These scales assume that data are in percentages (i.e., range 0 to 100 rather than 0 to 1).

scale_x_abundance(
  ...,
  limits = c(0, NA),
  breaks = seq(10, 90, 30),
  minor_breaks = seq(0, 100, 10),
  expand = c(0, 1)
)

scale_y_abundance(
  ...,
  limits = c(0, NA),
  breaks = seq(10, 90, 30),
  minor_breaks = seq(0, 100, 10),
  expand = c(0, 1)
)

Arguments

...: Passed to scale_y_continuous or scale_x_continuous
limits: Limits for the scale
breaks: Where to place labels on the scale
minor_breaks: Where to place minor breaks
expand: A vector of expantion constants

Value

A scale_y_continuous or scale_x_continuous
