-\title{DEPRECATED: Generate an error if an expression is not true.}
-\description{
-  Generate an error if an expression is not true.
-}
-\note{
-  This function is deprecated in favor of \code{\link[base]{stopifnot}}
-}
-\usage{
-assert(FLAG)
-}
-\arguments{
-  \item{FLAG}{ Expression that should evaluate to a boolean vector}
-}
-\details{
-  Assert generate an error if its aregument does not evaluate to 
-  boolean (vector) containing only \code{TRUE} values.  This is useful
-  for defensinve programming as it provides a mechanism for checking
-  that certain facts, the 'assertions', do in fact hold.  Checking of 
-  'assertions' is an important tool in the development of robust program
-  code.
-}
-\value{
-  None.  Evaluated only for its side effect.
