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`
