R help - May 2005 - help : Bisect( )

I  am using the package of  Icens
 but for the function  Bisect

  I do not know  what  ndir is

  it just says the direction of pvec, but what kind of values should I 
use ?

 thanks for reply

  pls give me an example..

 


Bisect(tA, pvec, ndir, Meps, tolbis=1e-07)

Arguments:

      tA: The transpose of the clique matrix.

    pvec: The current estimate of the probability vector.

    ndir: The direction to explore.

    Meps: Machine epsilon, elements of 'pvec' that are less than this
          are assumed to be zero.

  tolbis: The tolerance used to determine if the algorithm has
          converged.
