timepoint

a vector indicating timepoint at which each sample was collected or a character string equal to one of the column names of a supplied ExpressionSet.

group

a vector indicating a group membership for each sample or a character string equal to one of the column names of a supplied ExpressionSet If not specified, the group is set to 'G1' for each sample.

replicate

a vector indicating a replicate id of each sample or a character string equal to one of the column names of a supplied ExpressionSet If not specified, the replicate is set to 'R1' for each sample.
