starts_with_any_of(x, target)

Arguments

x

a string (or vector or list of strings)

target

a vector or list of strings

TRUE if x starts with any of the strings in target, FALSE otherwise. If x is a vector or list of strings, the return value is the same length as x and contains the result of applying the test to each item in x.

Details

This function is vectorized. If x is a vector or list of strings, the return value has the same length as x and contains the result of applying the test (does x start with any of target) for each item in x.

Examples

starts_with_any_of(x = "prefix - suffix", target = c("a", "b", "prefix"))
#> [1] TRUE
starts_with_any_of(x = "prefix - suffix", target = c("a", "b", "c"))
#> [1] FALSE
starts_with_any_of(x = "prefix - suffix", target = "suffix")
#> [1] FALSE
starts_with_any_of(x = c("Production - Crude", "Production - NG", "Exports - Oil", "Exports - Crude"), target = c("Production", "Imports"))
