Assert that objects share the same length — assert_same_length • assert

Checks that every object passed in ... has the same length. Useful before element-wise operations on parallel vectors or columns.

Usage

assert_same_length(..., call = rlang::caller_env())

Arguments

...: Two or more objects to compare. Their lengths must all be equal.
call: Environment used as the error's call context. Defaults to the calling function, so errors point at the user's code.

Value

The first object in ..., invisibly.

Examples

assert_same_length(c(1, 2, 3), c("a", "b", "c"))
