Arguments

string

A character vector.

pattern

A character vector. Pattern(s) specified like the pattern(s) in the stringr package (e.g. look at stringr::str_locate()). If this has length >1 its length must be the same as that of string.

n

Natural numbers.

m

Natural numbers.

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).

leave_as_string

Do you want to return the number as a string (TRUE) or as numeric (FALSE, the default)?
