Type & Coercion Errors

Unimplemented type

Matches: unimplemented type '([^']+)' in

WHAT THIS ERROR MEANS

You passed an object type that the function doesn't support. Often happens when passing a list where a vector is expected.

1. Check the type with typeof() or class().

2. Convert to the expected type (unlist() for lists → vectors).

3. Extract the specific element you need from the list.

BAD — THIS CAUSES THE ERROR

sort(list(3, 1, 2))

GOOD — CORRECT APPROACH

sort(c(3, 1, 2))  # use a vector, not a list
