Color in database diagrams

dm_set_colors() allows to define the colors that will be used to display the tables of the data model with dm_draw(). The colors can either be specified with hex color codes or using the names of the built-in R colors. An overview of the colors corresponding to the standard color names can be found at the bottom of https://rpubs.com/krlmlr/colors.

dm_get_colors() returns the colors defined for a data model.

dm_get_available_colors() returns an overview of the names of the available colors These are the standard colors also returned by grDevices::colors() plus a default table color with the name "default".

Usage

dm_set_colors(dm, ...)

dm_get_colors(dm)

dm_get_available_colors()

Arguments

dm

A dm object.

...

Colors to set in the form color = table. Allowed colors are all hex coded colors (quoted) and the color names from dm_get_available_colors(). tidyselect is supported, see dplyr::select() for details on the semantics.

Value

For dm_set_colors(): the updated data model.

For dm_get_colors(), a named character vector of table names with the colors in the names. This allows calling dm_set_colors(!!!dm_get_colors(...)). Use tibble::enframe() to convert this to a tibble.

For dm_get_available_colors(), a vector with the available colors.

Examples

dm_nycflights13(color = FALSE) %>%
  dm_set_colors(
    darkblue = starts_with("air"),
    "#5986C4" = flights
  ) %>%
  dm_draw()

# Splicing is supported:
nyc_cols <-
  dm_nycflights13() %>%
  dm_get_colors()
nyc_cols
#>  #ED7D31FF  #ED7D31FF  #5B9BD5FF  #ED7D31FF  #70AD47FF 
#> "airlines" "airports"  "flights"   "planes"  "weather" 

dm_nycflights13(color = FALSE) %>%
  dm_set_colors(!!!nyc_cols) %>%
  dm_draw()
