\description{
use the Pocock-Simon or Taves algorithm for computing covariate-adaptive
'minimization' allocations
for a clinical trial
}
\usage{
minimizePocSim(df, features, trtvec, obsdf, trttab, f = function(x, y) sum(abs(x + 1 - y)))
minimizeTaves(df, features, trtvec, obsdf, trttab)
}
%- maybe also 'usage' for other objects documented here.
\arguments{
  \item{df}{
a data frame with columns corresponding to covariates
rows corresponding to subjects
}
  \item{features}{
character vector of covariates to use
}
  \item{trtvec}{
vector of assignments made so far
}
  \item{obsdf}{
data frame for incoming observation, with values for
all components enumerated in \code{features}
}
  \item{trttab}{
table of treatment ratios
}
  \item{f}{
score that determines impending allocation
}
}
\details{
These functions are generally not called directly.
See the vignette; if supplied as the method slot of
a MinimizationDesc object the appropriate data are
assembled as arguments to these functions.
