Yes you first example shows what case_whendoes by design: It evaluates all the RHS before filtering to the correct condition, so yes all the assignment are made. !! Inconsistent types will throw an error.# This applies also to NA values used in RHS: NA is logical, use# typed values like NA_real_, NA_complex, NA_character_, NA_integer_ as appropriate.# case_when() evaluates all RHS expressions, and then constructs its# result by extracting the selected (via the LHS expressions) parts.# This throws an error as NA is logical not numeric# case_when is particularly useful inside mutate when you want to# create a new variable that relies on a complex combination of existing
