\title{Omits Observations with NA, NaN, Inf and -Inf Values}
\description{
  Omits observations with values which a not regular (=Not a Regular
  Value) when object is a vector, a factor, a data.frame or a matrix. 
}
\usage{
NaRV.omit(x)
}

\arguments{
  \item{x}{\code{Vector}, \code{data.frame} or \code{matrix}}
}
\details{
  Irregular values are defined as \code{NA}, \code{NaN}, \code{Inf} and
  \code{-Inf} Values in numerics and \code{NA} in factors and
  characters.  
}
\value{
  Returns objects of \code{class} vector, factor, data.frame or matrix
  in the same way as \code{\link{na.omit}} does.  Returns all other
  objects unchanged and prints a warning.
