ggplot2 colour scales matching fmrihrf plots — scale_colour_hrf • fmrihrf

Discrete colour and fill scales built on hrf_palette(). Use them in your own ggplot2 figures to match the output of plot_hrfs() and plot_regressors().

Usage

scale_colour_hrf(
  type = c("categorical", "ordered"),
  ...,
  aesthetics = "colour"
)

scale_color_hrf(type = c("categorical", "ordered"), ..., aesthetics = "colour")

scale_fill_hrf(type = c("categorical", "ordered"), ..., aesthetics = "fill")

Arguments

type: Either "categorical" or "ordered"; see hrf_palette().
...: Further arguments passed to ggplot2::discrete_scale(), such as name, labels, or guide.
aesthetics: The aesthetics the scale applies to.

Value

A ggplot2 scale object.

Examples

if (requireNamespace("ggplot2", quietly = TRUE)) {
  t <- seq(0, 24, by = 0.2)
  df <- data.frame(
    time = rep(t, 3),
    response = c(HRF_SPMG1(t), HRF_GAMMA(t), HRF_GAUSSIAN(t)),
    hrf = rep(c("SPMG1", "Gamma", "Gaussian"), each = length(t))
  )
  ggplot2::ggplot(df, ggplot2::aes(time, response, colour = hrf)) +
    ggplot2::geom_line() +
    scale_colour_hrf()
}
