annotateDGEobj {DGEobj}R Documentation

Add annotations


Reads an annotation file containing key/value pairs or a named list and attaches them attributes to a DGEobj. If a file is used, it should be a text file containing key/value pairs separated by an equals sign. The keys argument specifies which keys we want to capture as attributes on the DGEobj.


annotateDGEobj(dgeObj, annotations, keys = NULL)



A object of class DGEobj created by function initDGEobj()


Either a character string path to a file with annotations given as key/value pairs separated by an equal sign, or a named list of key/value pairs


By default (value = NULL), all keys are read in and applied as DGEobj attributes. Use the keys argument to specify a specific list of keys to read from the file.
