str_split_by_numbers: Split a string by its numeric characters.

Description

Break a string wherever you go from a numeric character to a non-numeric or vice-versa. Keep the whole string, just split it up. Vectorised over string.

Usage

str_split_by_numbers(
  string,
  decimals = FALSE,
  leading_decimals = FALSE,
  negs = FALSE,
  sci = FALSE,
  commas = FALSE
)

Arguments

string

A string.

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)).

Value

A list of character vectors.
