     yacmode()

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

     The user types valid yacas input and presses return. Type 'quit'
     to return to R prompt.

_V_a_l_u_e:

     Output of yacas is returned.

_N_o_t_e:

     Note that command recall will recall previous R commands, not
     previous yacas input. Yacas is given a limited amount of time to
     complete, otherwise '[1] CommandLine(1) : User interrupted
     calculation' is returned. E.g. Taylor(x,0,5) 1/(1+x) will work,
     but  Taylor(x,0,12) 1/(1+x) is likely to take too long.
