Generating a logical vector (7)

• either by doing (vectorized) comparisons (see before)

• or by combining logical vectors or comparisons = boolean algebra

  • operators: &, |, !, xor()
  • {magrittr} (through {dplyr}) provides the aliases and(), or(), not()

  
  In numerical operations, FALSE is 0 and TRUE is 1. Therefore:

  • & can be mimicked by pmin()
  • | can be mimicked by pmax()
