GOChord: Displays the relationship between genes and terms.
In StarBioTrek: StarBioTrek

The GOChord function generates a circularly composited overview of selected/specific genes and their assigned processes or terms. More generally, it joins genes and processes via ribbons in an intersection-like graph.

1 2	GOChord(data, title, space, gene.order, gene.size, gene.space, nlfc = 1, lfc.col, lfc.min, lfc.max, ribbon.col, border.size, process.label, limit)

`data`	The matrix represents the binary relation (1= is related to, 0= is not related to) between a set of genes (rows) and processes (columns); a column for the logFC of the genes is optional
`title`	The title (on top) of the plot
`space`	The space between the chord segments of the plot
`gene.order`	A character vector defining the order of the displayed gene labels
`gene.size`	The size of the gene labels
`gene.space`	The space between the gene labels and the segement of the logFC
`nlfc`	Defines the number of logFC columns (default=1)
`lfc.col`	The fill color for the logFC specified in the following form: c(color for low values, color for the mid point, color for the high values)
`lfc.min`	Specifies the minimium value of the logFC scale (default = -3)
`lfc.max`	Specifies the maximum value of the logFC scale (default = 3)
`ribbon.col`	The background color of the ribbons
`border.size`	Defines the size of the ribbon borders
`process.label`	The size of the legend entries
`limit`	A vector with two cutoff values (default= c(0,0)).
