R language definition is not tokenizing the code.

🐛 Bug Report

I am using prism-vsc-dark-plus.css theme, in my node.js, react, tailwind environment and R language is not tokenizing as below HTML from Inspect Element shows:
R --->>

# Add 1 + 1

result <- 1 + 1
As a comparison, here's correctly formatted cpp using the same theme:
#include <iostream>



int main() {

    int dividend, divisor, quotient, remainder;

Here's the node_modules/prismjs/prism-r.js file
Prism.languages.r = {
	'comment': /#.*/,
	'string': {
		pattern: /(['"])(?:\\.|(?!\1)[^\\\r\n])*\1/,
		greedy: true
	},
	'percent-operator': {
		// Includes user-defined operators
		// and %%, %*%, %/%, %in%, %o%, %x%
		pattern: /%[^%\s]*%/,
		alias: 'operator'
	},
	'boolean': /\b(?:FALSE|TRUE)\b/,
	'ellipsis': /\.\.(?:\.|\d+)/,
	'number': [
		/\b(?:Inf|NaN)\b/,
		/(?:\b0x[\dA-Fa-f]+(?:\.\d*)?|\b\d+(?:\.\d*)?|\B\.\d+)(?:[EePp][+-]?\d+)?[iL]?/
	],
	'keyword': /\b(?:NA|NA_character_|NA_complex_|NA_integer_|NA_real_|NULL|break|else|for|function|if|in|next|repeat|while)\b/,
	'operator': /->?>?|<(?:=|=!]=?|::?|&&?|\|\|?|[+*\/^$@~]/,
	'punctuation': /[(){}\[\],;]/
};
