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.
