//' @title logit and inverse logit functions
//' 
//' @description
//' transform \code{x} either via the logit, or inverse logit.
//'
//' @details
//' The loogit and inverse logit functions are part of R via the
//' logistic distribution functions in the stats package.  
//' Quoting from the documentation for the logistic distribution
//'
//' "\code{qlogis(p)} is the same as the \code{logit} function, \code{logit(p) =
//' log(p/1-p)}, and \code{plogis(x)} has consequently been called the 'inverse
//' logit'."
//'
//' See the examples for benchmarking these functions.  The \code{logit} and
//' \code{invlogit} functions are faster than the \code{qlogis} and \code{plogis}
//' functions.
