Answer 1

A very simple way is

library(priceR)
values <- c(1e5, 2e5)
format_dollars(values)

# [1] "$100,000" "$200,000"

Notes

• Add decimal places with format_dollars(values, 2) i.e. "$100,000.00" "$200,000.00"
• For other currencies use format_currency(values, "€") which gives "€100,000" "€200,000" etc
