rmcfs (version 1.2.5)

plot.idgraph: Plots interdependencies graph

Description

Invokes plot.igraph with predefined parameters to visualize interdependencies graph (ID-Graph). Standard plot function with custom parameters may be used instead of this one.

Usage

# S3 method for idgraph
plot(x, 
          label_dist = 0.5, 
          cex = 1, …)

Arguments

x

idgraph/igraph S3 object representing feature interdependencies. This object is produced by build.idgraph function.

label_dist

space between the node's label and the corresponding node in the plot.

cex

size of fonts.

...

additional plotting parameters.

Examples

  ### Set up java parameter and load rmcfs package
  options(java.parameters = "-Xmx4g")
  library(rmcfs)
  
  # create input data
  adata <- artificial.data(rnd_features = 10)
  showme(adata)
  
  # Parametrize and run MCFS-ID procedure
  result <- mcfs(class~., adata, cutoffPermutations = 0, featureFreq = 50,
                  finalCV = FALSE, finalRuleset = FALSE, threadsNumber = 2)

  # build interdependencies graph for top 6 features 
  # and top 12 interdependencies and plot all nodes
  gid <- build.idgraph(result, size = 6, size_ID = 12, plot_all_nodes = TRUE)
  plot(gid, label_dist = 1)
