| mRagraph {classGraph} | R Documentation |
My constructor of an Ragraph
object, a kind of “laid-out” graph, from package
Rgraphviz. This allows more customization in plotting than just
calling plot(gr, ...) for a
graph object from package
graph.
mRagraph(gr, lType, fixedsize = FALSE,
fill = c("lightblue", "gray90"),
color = c("blue3", "gray60"),
labcol = c("blue3", "green4", "purple"))
gr |
an R object of class graph (from
package graph), in our case typically the result of
classTree(). |
lType |
a string specifying the layout type,
see agopen() in package Rgraphviz for the
possibilities. |
fixedsize |
logical indicating if the ellipses should all get the same size – or should rather adapt to the situation. |
fill |
character vector of length 2.... |
color |
character vector of length 2.... |
labcol |
vector of labels to be used .... |
an object of class Ragraph,
produced by an appropriate call to agopen.
