R: Split a string by its numeric characters.

str_split_by_numbers {strex}

R Documentation

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.

Examples

str_split_by_numbers(c("abc123def456.789gh", "a1b2c344"))
str_split_by_numbers("abc123def456.789gh", decimals = TRUE)
str_split_by_numbers(c("22", "1.2.3"), decimals = TRUE)
