Logical is a mode (and an implicit class) for vectors.

`TRUE`

, `FALSE`

and `NA`

are the only values for logical vectors; and all three are reserved words. `T`

and `F`

can be shorthand for `TRUE`

and `FALSE`

in a clean R session, but neither `T`

nor `F`

are reserved, so assignment of non-default values to those names can set users up for difficulties.
