RWiener R package
=================
The RWiener package is an extension for R, which provides wiener
process distribution functions, namely the Wiener first passage time
density, CDF, quantile and random functions. 

Using the package
-----------------
::

  dwiener(q, alpha,tau,beta,delta, resp="upper")
  pwiener(q, alpha,tau,beta,delta, resp="upper")
  qwiener(p, alpha,tau,beta,delta, resp="upper")
  rwiener(n, alpha,tau,beta,delta)
 
*arguments*:

- q being a quantile
- p being the CDF value between 0 and 1
- n being an integer value > 0
- resp determining if it's for the "upper" or "lower" (i.e. error) boundary
- alpha being the boundary separation parameter
- tau being the non-decision time
- beta being the bias
- delta being the drift rate

Further, the package includes functions to compute the likelihood, which
can be used in combination with R's optim() function, to get parameter
estimates for the model.
