_D_e_s_c_r_i_p_t_i_o_n:

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

_U_s_a_g_e:

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

_A_r_g_u_m_e_n_t_s:

  length: desired length.

       x: object to be coerced or tested.

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

_D_e_t_a_i_l_s:

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

     'as.real' and 'is.real' are primitive, so positional matching is
     used and any names of supplied arguments are ignored.  This may
     not be true of methods for 'as.real'.
