This function formats numeric values as dollar amounts by rounding them to the nearest whole number, adding commas as thousand separators, and prefixing them with a dollar sign.
Examples
dollarize(1234567.89) # Returns "$1,234,568"
#> [1] "$1,234,568"
dollarize(c(1000, 2500.75, 999999.99)) # Returns c("$1,000", "$2,501", "$1,000,000")
#> [1] "$1,000" "$2,501" "$1,000,000"
