     censcale(x, tol = 0.0001)

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

       x: Matrix of observations.

     tol: Threshold for column scaling. A column is divided
          by the square root of its variance (standard devi-
          ation) when that quantity exceeds `tol', The
          default value is `0.0001'.

_V_a_l_u_e_:

     The centered and scaled matrix of observations.

_D_E_S_C_R_I_P_T_I_O_N_:

     Transforms a data set by subtracting the column mean
     from each column and dividing each column by the square
     root of its variance when the latter is sufficiently
     large in magnitude.
