show_col

Show colours

A quick and dirty way to show colours in a plot.

show_col(colours, labels = TRUE, borders = NULL, cex_label = 1, ncol = NULL)

`colours`	A character vector of colours
`labels`	Label each colour with its hex name?
`borders`	Border colour for each tile. Default uses `par("fg")`. Use `border = NA` to omit borders.
`cex_label`	Size of printed labels, as multiplier of default size.
`ncol`	Number of columns. If not supplied, tries to be as square as possible.

show_col(hue_pal()(9))
show_col(hue_pal()(9), borders = NA)

show_col(viridis_pal()(16))
show_col(viridis_pal()(16), labels = FALSE)
