Generating a logical vector (1)

• either by doing (vectorized) comparisons

  operators:

  • one-to-one: ==, !=, <, <=, >, >=
  • one-to-many: %in%

  
  Comparisons are often the way that logical vectors arise, i.e. during exploration, cleaning and analysis

  • … unless the logical vector is already provided, e.g. the observed variable is boolean.
