Re: [R] searchina a pattern in a string

If it was only numbers with no dashes or up to 2 dashes, you can do it like this: require(stringr) STRING - my no is 9876543210 is personal no and my official no is 123-456-8907. you can use any of these str_extract_all( STRING , [0-9]+-*[0-9]+-*[0-9]+) (and then clean the numbers...)
