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,
  big_mark = "",
  commas = FALSE
)

Value

A list of character vectors.

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.

big_mark

A character. Allow this character to be used as a thousands separator. This character will be removed from between digits before they are converted to numeric. You may specify many at once by pasting them together e.g. big_mark = ",_" will allow both commas and underscores. Internally, this will be used inside a [] regex block so e.g. "a-z" will behave differently to "az-". Most common separators (commas, spaces, underscores) should work fine.

commas

Deprecated. Use big_mark instead.
