%description
Functions to assist in R programming, including: - assist in developing,
updating, and maintaining R and R packages ('ask', 'checkRVersion',
'getDependencies', 'keywords', 'scat'), - calculate the logit and inverse
logit transformations ('logit', 'inv.logit'), - test if a value is
missing, empty or contains only NA and NULL values ('invalid'), -
manipulate R's .Last function ('addLast'), - define macros ('defmacro'), -
detect odd and even integers ('odd', 'even'), - convert strings containing
non-ASCII characters (like single quotes) to plain ASCII ('ASCIIfy'), -
perform a binary search ('binsearch'), - sort strings containing both
numeric and character components ('mixedsort'), - create a factor variable
from the quantiles of a continuous variable ('quantcut'), - enumerate
permutations and combinations ('combinations', 'permutation'), - calculate
and convert between fold-change and log-ratio ('foldchange',
'logratio2foldchange', 'foldchange2logratio'), - calculate probabilities
and generate random numbers from Dirichlet distributions ('rdirichlet',
'ddirichlet'), - apply a function over adjacent subsets of a vector
('running'), - modify the TCP_NODELAY ('de-Nagle') flag for socket
objects, - efficient 'rbind' of data frames, even if the column names
don't match ('smartbind'), - generate significance stars from p-values
('stars.pval'), - convert characters to/from ASCII codes ('asc', 'chr'), -
convert character vector to ASCII representation ('ASCIIfy'), - apply
title capitalization rules to a character vector ('capwords').
