A class definition for graphs that are based on distances.
Objects from the Class
Objects can be created by calls of the form
- Object of class
"dist"that forms the basis for the edge weights used in the
signature(object = "distGraph"): a print method
signature(object = "distGraph"): return the dist object.
signature(object = "distGraph"): find the nodes adjacent to the supplied node.
signature(object = "distGraph"): return the nodes in the graph.
signature(object = "distGraph"): return the number of nodes.
signature(object = "distGraph", k, value): set all distances that are larger than the supplied threshold,
k, to the supplied value. The default is value is zero (and so is appropriate for similarities, rather than distances).
signature(object = "distGraph"): initialize a
- Return a list of edge weights in a list format
similar to the
signature(graph = "distGraph"): A method for obtaining the edge list.
Shamir's paper and Butte et al
set.seed(123) x <- rnorm(26) names(x) <- letters library(stats) d1 <- dist(x) g1 <- new("distGraph", Dist=d1)
Looks like there are no examples yet.
