Outside of domain returns na.color

Code
  col_factor(bw, letters, na.color = NA)("foo")
Condition
  Warning:
  Some values were outside the color scale and will be treated as NA
Output
  [1] NA

Code
  col_quantile(bw, 0:1, na.color = NA)(-1)
Condition
  Warning:
  Some values were outside the color scale and will be treated as NA
Output
  [1] NA

Code
  col_quantile(bw, 0:1, na.color = NA)(2)
Condition
  Warning:
  Some values were outside the color scale and will be treated as NA
Output
  [1] NA

Code
  col_numeric(bw, c(0, 1), na.color = NA)(-1)
Condition
  Warning:
  Some values were outside the color scale and will be treated as NA
Output
  [1] NA

Code
  col_numeric(bw, c(0, 1), na.color = NA)(2)
Condition
  Warning:
  Some values were outside the color scale and will be treated as NA
Output
  [1] NA

factors match by name, not position

Code
  col <- pal(letters[10:20])
Condition
  Warning:
  Some values were outside the color scale and will be treated as NA

qualitative palettes don't interpolate

Code
  pal(letters[6])
Condition
  Warning:
  Some values were outside the color scale and will be treated as NA
Output
  [1] NA

OK, qualitative palettes sometimes interpolate

Code
  result <- pal(letters[1:20])
Condition
  Warning in `RColorBrewer::brewer.pal()`:
  n too large, allowed maximum for palette Accent is 8
  Returning the palette you asked for with that many colors

col_quantile handles skewed data

Code
  x <- c(1:5, rep(10, 10))
  col <- col_quantile("RdYlBu", domain = x, n = 7)(x)
Condition
  Warning:
  Skewed data means we can only allocate 4 unique colours not the 7 requested
Code
  col <- col_quantile("RdYlBu", domain = NULL, n = 7)(x)
Condition
  Warning:
  Skewed data means we can only allocate 4 unique colours not the 7 requested
