Mark Individual Pair Typess in Point Cloud (eo)


Mark individual pair types from a data set in a point cloud plotted with the eo.points function.


eo.mark(ds, select, style=1, bw=bw, cex=1.5, lwd=3,


ds a data set containing pair types that have been plotted as a point cloud, some or all of which will be marked
select an expression that will be evaluated on the data set ds to determine the pair types that will be marked. In order to mark the point representing the word pair black box, e.g., specify select=(l1 == "black" & l2 == "box").
style an integer specifying the style from which the colour of the markers is taken. Note that the symbol (a thick ring) and its size are hard-coded in the function and cannot be changed globally.
bw If TRUE, the markers are drawn in B/W mode, otherwise in colour mode. This parameter only affects the colour of the marker rings. It defaults to the state specified with the initial eo.setup call, but can be overridden manually.
cex, lwd size and thickness of the marker rings. The default values are suitable for the "factory setting" styles used for data set points (see eo.points).
jitter If TRUE, the coordinates of pair types are jittered for the plot. This parameter must have the same value as in the eo.points call that was used to plot the point cloud, otherwise marker placement will be incorrect. When jitter=TRUE, the data set has to be annotated with the add.jitter function first. The default value is set with eo.par.


See the eo.setup help page for a description of the general procedure used to create (e,o) plots. This help page also has links to other (e,o) plotting functions. The "factory setting" styles are described on the eo.par help page.
