)
}
\arguments{
\item{meta_data}{Meta data provided by TCGA}

\item{cancer_data}{A large list created prior by multimodalR for a cancer site}

\item{key}{character - Unique identifier, default = "case_id"}

\item{additional_key}{needs to be added}

\item{additional_value}{needs to be added}
}

\description{
This function subsets the metadata for an organ. It works for meta data directly downloaded from TCGA or already filtered meta data. The subset is done by matching the "key" with the column names (patient ID or case_id) of the expression matrix.

lungMetaData <- subset_metadata(metadata, lungXY)
