\alias{filter_zero}
\title{Filter 0 Sum Rows}
\usage{
filter_zero(summarized_experiment, assay_index = 1)
}
\arguments{
\item{summarized_experiment}{Matrix like object (data frame etc.) or SummarizedExperiment}

\item{assay_index}{Integer - index of assay of gene expression if input object is a SummarizedExperiment.}
}
\value{
SummarizedExperiment with probably less genes than before.
}
\description{
This function filters rows with row sums of zero (no expression)
}
\details{
This function is somewhat redundant, when you use \code{\link{filter_zero}} rows with zero sums are filtered out as well.
}
\examples{
filteredBreastBRCA <- filter_zero(breastBRCA, assay_index = 1) #filtering is applied to first assay
