Combine Factors in Targets File

Description

This is a helper function for data/aSVGs involving three or more factors such as sample, time, condition. It combine factors in targets file to make composite factors.

Usage

com_factor(se, target, factors2com, sep = ".", factor.new)

Arguments

se	A SummarizedExperiment object.
target	A data.frame object of targets file.
factors2com	A character vector of column names or a numeric vector of column indeces in the targets file. Entries in these columns are combined.
sep	The separator in the combined factors. One of _, and . (default).
factor.new	The column name of the new combined factors.

Value

If se is provided, a SummarizedExperiment object is returned, where the colData slot contains the new column of combined factors. Otherwise, adata.frame object is returned, where the new column of combined factors is appended.
