 Logical vectors are the simplest type of atomic vector because they can take only three possible values: `FALSE`, `TRUE`, and `NA`. Logical vectors are usually constructed with comparison operators, as described in [comparisons]. You can also create them by hand with `c()`:
 
 ```{r}
-1:10 %% 3
+1:10 %% 3 == 0
 
 c(TRUE, TRUE, FALSE, NA)
