scale_X_continuous: Ternary Position Scales
In leogama/ggtern: An Extension to 'ggplot2', for the Creation of Ternary Diagrams

Define the ternary continuous position scales (T, L & R).

scale_T_continuous(name = waiver(), limits = NULL, breaks = waiver(),
  minor_breaks = waiver(), labels = waiver(), ...)

scale_L_continuous(name = waiver(), limits = NULL, breaks = waiver(),
  minor_breaks = waiver(), labels = waiver(), ...)

scale_R_continuous(name = waiver(), limits = NULL, breaks = waiver(),
  minor_breaks = waiver(), labels = waiver(), ...)

`name`	The name of the scale. Used as the 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.
`limits`	One of: `NULL` to use the default scale range A numeric vector of length two providing limits of the scale. Use `NA` to refer to the existing minimum or maximum A function that accepts the existing (automatic) limits and returns new limits Note that setting limits on positional scales will remove data outside of the limits. If the purpose is to zoom, use the limit argument in the coordinate system (see `coord_cartesian()`).
`breaks`	One of: `NULL` for no breaks `waiver()` for the default breaks computed by the transformation object A numeric vector of positions A function that takes the limits as input and returns breaks as output (e.g., a function returned by `scales::extended_breaks()`)
`minor_breaks`	One of: `NULL` for no minor breaks `waiver()` for the default breaks (one minor break between each major break) A numeric vector of positions A function that given the limits returns a vector of minor breaks.
`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
`...`	not used
