clusterData-methods {Rgraphviz} | R Documentation

## Get and set attributes for a cluster of an Ragraph object

### Description

Attributes of a graph can be accessed using `clusterData`. There's no default attributes for clusters. The attributes must be defined using `graphDataDefaults`.

### Usage

    clusterData(self, cluster, attr)
    clusterData(self, cluster, attr) <- value

### Arguments

`self` | A `Ragraph-class` instance
`cluster` | cluster number
`attr` | A `character` vector of length one specifying the name of a cluster attribute
`value` | A `character` vector to store as the attribute value

                                package="graph"))
    g11_gz <- gzfile(system.file("GXL/graphExample-11.gxl.gz",
                                 package="graph"))
    if(require(XML)) {
      g1 <- fromGXL(g1_gz)
      g11 <- fromGXL(g11_gz)
      g1_11 <- join(g1, g11)
      sgl <- vector(mode="list", length=2)
      sgl[[1]] <- list(graph=g1, cluster=TRUE)
      sgl[[2]] <- list(graph=g11, cluster=TRUE)
      ng <- agopenSimple(g1_11, "tmpsg", subGList=sgl)
      clusterData(ng, 1, c("bgcolor")) <- c("blue")
      clusterData(ng, 2, c("bgcolor")) <- c("red")
      toFile(ng, layoutType="dot", filename="g1_11_dot.ps", fileType="ps")
    }
