NA styling

[hadley]

I'm not in love with the current treatment. Did we try yellow or red foreground colour?

Please choose your preference, screenshot taken in RStudio:

Code to create the matrix:

bg <- c("bgBlack", "bgBlue", "bgCyan", "bgGreen", "bgMagenta", "bgRed", "bgWhite", "bgYellow")
fg <- tolower(gsub("^bg", "", bg))

library(tidyverse)
library(crayon)

combs <- tidyr::crossing(bg, fg)

find_fun <- function(name) {
  get(name, asNamespace("crayon"), mode = "function")
}

combs %>%
  rowwise() %>% 
  mutate(na = find_fun(fg)(find_fun(bg)("NA"))) %>% 
  ungroup() %>% 
  group_by(bg) %>% 
  summarize(na = paste(na, collapse = " ")) %>% 
  ungroup() %>%
  summarize(val = paste0(format(bg), " ", na, collapse = "\n")) %>%
  pull() %>% 
  cat()

Let's try bgRed + white

Actually, let's just try "red" and leave the background colour alone. I think that should be sufficient contrast in most styling configs.

I do wonder why bgWhite() is so gray on my system...
