Computes Seasonal Means
}
\description{
Computes seasonal means on timeseries organized in a matrix of any number of dimensions up to 10 dimensions where the time dimension is one of those 10 dimensions.
}
\usage{
Season(var, posdim = 4, monini, moninf, monsup)
}
\arguments{
  \item{var}{
Matrix containing the timeseries along one of its dimensions.
  }
  \item{posdim}{
Dimension along which to compute seasonal means = Time dimension
  }
  \item{monini}{
First month of the time-series: 1 to 12.
  }
  \item{moninf}{
Month when to start the seasonal means: 1 to 12.
  }
  \item{monsup}{
Month when to stop the seasonal means: 1 to 12.
  }
}
\value{
Matrix with the same dimensions as var except along the posdim dimension which length corresponds to the number of seasons. Partial seasons are not accounted for.
}
