Real Vectors

Description:

     These functions are the same as their 'double' equivalents and are
     provided for backwards compatibility only.

Usage:

     real(length = 0)
     as.real(x, ...)
     is.real(x)

Arguments:

  length: desired length.

       x: object to be coerced or tested.

     ...: further arguments passed to or from other methods.

Details:

     'as.real' is a generic function, but S3 methods must be written
     for 'as.double'.
