Arguments

string	A character vector.
pattern	The pattern to look for. The default interpretation is a regular expression, as described in stringi::about_search_regex. To match a without regular expression (i.e. as a human would), use coll(). For details see stringr::regex().
n, m	Vectors of integerish values. Must be either length 1 or have length equal to the length of string. Negative indices count from the back: while 1 and 2 correspond to first and second, -1 and -2 correspond to last and second-last. 0 will return NA.
decimals	Do you want to include the possibility of decimal numbers (TRUE) or not (FALSE, the default).
leading_decimals	Do you want to allow a leading decimal point to be the start of a number?
negs	Do you want to allow negative numbers? Note that double negatives are not handled here (see the examples).
sci	Make the search aware of scientific notation e.g. 2e3 is the same as 2000.
commas	Allow comma separators in numbers (i.e. interpret 1,100 as a single number (one thousand one hundred) rather than two numbers (one and one hundred)).
leave_as_string	Do you want to return the number as a string (TRUE) or as numeric (FALSE, the default)?
