Create continuous-palette function from HCL parameters

Create continuous-palette function from HCL parameters

pev_fcont_diverging(.fcont_low, .fcont_high)

Arguments

.fcont_low	object that can be coerced to pev_fcont, similar to .fcont, used for the low end of a diverging scale. Low end of this scale becomes the middle of the diverging scale.
.fcont_high	object that can be coerced to pev_fcont, similar to .fcont, used for the high end of a diverging scale. Low end of this scale becomes the middle of the diverging scale.

Value

function with S3 class pev_fcont, when called with a numeric vector with values between 0 and 1, returns the corresponding (hex-code) values.

Examples

  # Create sequential-palette functions
  fcont_purple <- pev_fcont("Purples 3")
  fcont_green <- pev_fcont("Greens 3")

  # Create diverging-palette function
  pev_fcont_diverging(fcont_purple, fcont_green)
