Usage

hex2rgb(hex)

Arguments

hex

Character vector of HEX color codes (e.g. "#FF8000" or "#FF8000B2"). Both 6-digit and 8-digit (with alpha) codes are accepted. The # prefix is required. No NA values allowed.

Value

Examples

hex2rgb("#FF8000")
#>       hex   r   g b alpha
#> 1 #FF8000 255 128 0    NA
hex2rgb(c("#FF8000", "#00FF00"))
#>       hex   r   g b alpha
#> 1 #FF8000 255 128 0    NA
#> 2 #00FF00   0 255 0    NA
