Arguments

y	A numeric matrix

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)

Value

A list with following items:

Estimates	Summary values for each column.
StdErrors	Standard error estimates.
