     Those functions are low-level functions used by `errorest' and are
     normally not called by users.

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

     bootest(y, formula, data, model, predict, nboot=25, bc632plus=FALSE, ...)

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

       y: the response variable, either of class `factor'
          (classification), `numeric' (regression) or `Surv'
          (survival).

 formula: a formula object.

    data: data frame of predictors and response described in `formula'.

   model: a function implementing the predictive model to be evaluated.
          The function `model' can either return an object representing
          a fitted model or a function with argument `newdata' which
          returns predicted values. In this case, the `predict'
          argument to `errorest' is ignored.

 predict: a function with arguments `object' and `newdata' only which
          predicts the status of the observations in `newdata' based on
          the fitted model in `object'.

   nboot: number of bootstrap replications to be used.

bc632plus: logical. Should the bias corrected version of
          misclassification error be computed?

     ...: additional arguments to `model'.

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

     See `errorest'.
