ldbounds 2.0.0

• Print Methods

   * Created print.ldBounds: almost identical to summary 
          (just leaves off the exit probabilities)
  
   * Created print.ldPower: almost identical to summary
          (just leaves off the exit probs, and puts the
          lower/upper probs up with the boundaries, instead
          of separating)
  
   * Edited summary.ldPower: to give power when drift is
          known (put space before probs table)

• Better two-sided bounds and defaults rather than weird parameters

   * Created sides argument for ldBounds
  
   * Added ability to specify the number of looks, which
          then automatically creates equally spaced analysis
          times
  
   * Sides=2, but with only one alpha, etc, creates
          symmetric bounds, splitting the provided alpha in
          half for each, upper and lower bounds
  
   * Print and summary functions updated to account for
          this

• ldPower to use output from ldBounds

   * ldPower can now accept an ldBounds object as the first
          argument, in which case, it does not require za,
          zb, t, t2
  
   * Defaults to drift=0 when nothing is specified

• Nominal alpha level at each look provided (for one-sided or symmetric bounds)

   * ldBounds now has additional value: nominal alpha at
          each look.
  
   * Summary.ldBounds displays this

• asf changed from asf/alpha to asf

   * asf now uses just asf rather than asf alpha (this
          was only a change to alphas function)

• Weird integer errors

   * ldBounds and alphas now have checks that take into
          account floats

• Ability to specify non-alpha spending boundaries

   * Created new function commonbounds to calculate
          Pocock or O{'}Brien-Fleming (non-alpha-spending)
          bounds at equally spaced times.
  
   * These also become ldBounds objects
  
   * Adjusted print and summary functions to accommodate

• Calculate adjusted p-values

   * Added p-value functionality to ldPower function;
          stepwise and likelihood ratio ordering available.
  
   * Uses a new adj.p function which, ironically, calls
          ldPower.
  
   * Edited printing and summary functions to use this
          as well.

• Graphics

   * Now uses base graphics, very simple
  
   * Option to show on either z-value or b-value scale
  
   * Ability to add to existing plot

• Conditional power

   * Added condpower, a function to calculate simple
          conditional power
