Details

This groups of functions summarize the columns of a given matrices.

• colSummarizeAvgTake means in column-wise manner
• colSummarizeAvgLoglog2 transform the data and then take means in column-wise manner
• colSummarizeBiweightSummarize each column using a one step Tukey Biweight procedure
• colSummarizeBiweightLoglog2 transform the data and then summarize each column using a one step Tuke Biweight procedure
• colSummarizeLogAvgCompute the mean of each column and then log2 transform it
• colSummarizeLogMedianCompute the median of each column and then log2 transform it
• colSummarizeMedianCompute the median of each column
• colSummarizeMedianLoglog2 transform the data and then summarize each column using the median
• colSummarizeMedianpolishUse the median polish to summarize each column, by also using a row effect (not returned)
• colSummarizeMedianpolishLoglog2 transform the data and then use the median polish to summarize each column, by also using a row effect (not returned)
