A numeric matrix |
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)
