addPaths:
Function to load gene pathways into maigesPreRaw object
Description
This function read a directory and read files containing the gene
pathways in TGF format. This format must have the genes of the pathway
sequentially in lines numbered from 1, followed by a '\#' character
that separate the nodes (given by genes) from edges, that must be
specified as number of the origin gene followed by a space, the number
of the final gene, another space and the weight of the iteration. This
function stores the gene networks read in the slot Paths into
objects of class maigesPreRaw.
char string specifying the directory of gene groups. The
function tests the presence or not of the final bar.
ext
string giving the extension of the files, defaults to
'.tgf'. The function also tests the presence of the initial dot.
Value
This function return another object of class
maigesPreRaw, with the slot Paths actualised.
Details
If the data object already has gene networks with names equal
to some someones that are been read, the nets with repeated names
are not added. Warning messages are printed for every repeated group
name.
The folder directory must contain only one file for each pathway
of interest. These files must be done in TGF format, as described into
description above. The gene identification are matched with some
column from genemap (see loadData).
