ladder

Searches the ladder of powers histograms to find a transformation to make
<code>x</code> normally distributed. The Shapiro-Wilkes test is used to assess for
normality. The following transformations are included: identity, cubic,
square, square root, natural logarithm, inverse square root, inverse, 
inverse square, and inverse cubic.

Helper functions for descriptive tasks such as making print-friendly bivariate
tables, sample size flow counts, and visualizing sample distributions. Also
contains 'R' approximations of some common 'SAS' and 'Stata' functions such
as 'PROC MEANS' from 'SAS' and 'ladder', 'gladder', and 'pwcorr' from 'Stata'.
