### 3.4 R boolean objects

The RPy module provides, as a convenience, the `TRUE` and `FALSE` R objects, as attributes to the `r` Python object (i.e.: `r.TRUE` and `r.FALSE`). For example:

    >>> r.TRUE
    <Robj object at 0x8b3a498>
    >>> r.typeof(r.TRUE)
    'logical'

Note that the `T` and `F` names from R are variables bounded to the logical objects; however, they can be rebound. So, `r.T` and `r.F` may not be the objects you expect. Use `r.TRUE` and `r.FALSE` instead.
