A numeric matrix |
group.labels |
A vector to be treated as a factor variable. This is used to assign each row to a group. NA values should be used to exclude rows from consideration |
These functions are designed to summarize the columns of a matrix where the rows of the matrix are assigned to groups. The summarization is by column across all rows in each group.
log2
transform the data and
then take means in column-wise manner
log2
transform the data and
then use a one-step Tukey Biweight to
summarize columns
log2
log2
log2
transform the data and
then summarize by taking median
log2
transform the
data and then use the median polish to summarize each column, by
also using a row effect (not returned)
A matrix
containing column summarized data. Each row
corresponds to data column summarized over a group of rows.
