Slice substrings from a string — strs

strs_slice extracts substrings from each element of a character vector, specified by start and stop positions. It is similar to Python's slicing syntax for strings, but it uses 1 indexing and stops are inclusive.

Usage

strs_slice(string, start = 1L, stop = -1L, ..., step = 1L)

Arguments

string: A character vector where each element is a string to slice.
start: An integerish scalar for the starting position for slicing (inclusive).
stop: An integerish scalar for the ending position for slicing (inclusive).
...: Used to force keyword argument usage of step.
step: An integer greater than 0 or equal to -1 for the step size. If -1 is provided, each string will be reversed after slicing operations.

Value

A character vector of the same length as string, with each element being the sliced substring.

Examples

strs_slice("hello world", 1, 5)
#> [1] "hello"
strs_slice("hello world", 7)
#> [1] "world"
strs_slice("hello world", start = 7, stop = 11)
#> [1] "world"
