\title{Size.globalSeg}
\description{
  Tools  manipulating size,max,min,length of elements of class globalSeg
}
\usage{
size.globalSeg(a)
Max.globalSeg(a)
Min.globalSeg(a)
Length.globalSeg(a,global=TRUE)
}

\arguments{
  \item{a}{elements of class globalSeg}
  \item{global}{if TRUE: return one value (number segments)
  if FALSE return a vector (number of segments in each elements of the list)}
}
\value{
  return a vector with min, max, size or length of each element of
  the list (a element of class globalSeg is a list of elements of class segments).
