Map a single base to the corresponding number (generic ggDNAvis helper)

This function takes a single base and numerically encodes it for visualisation via raster::raster().

Encoding: A = 1, C = 2, G = 3, T/U = 4.

Usage

convert_base_to_number(base)

Arguments

base

character. A single DNA/RNA base to encode numerically (e.g. "A").

Value

integer. The corresponding number.

Examples

convert_base_to_number("A")
#> [1] 1
convert_base_to_number("c")
#> [1] 2
convert_base_to_number("g")
#> [1] 3
convert_base_to_number("T")
#> [1] 4
convert_base_to_number("u")
#> [1] 4
