Click on Graphviz, and then go to "File" -> "open" to open the folder that contains Hgraph.dot and Igraph.dot.Find Graphviz in your application folder if it is not on your desktop bar.To visualize the I-graph, after opening I-graph, i.e., Igraph.dot, in Graphviz, set Layout Engine to 'neato'įigure 5: Choosing Layout Engine neato for I-graph Now you should see the following H-graph in Graphviz.Ĥ. Change the layout engine to 'fdp' by going to Graph -> Settings ->įigure 3: Choosing Layout Engine fdp for H-graph You will see a graph pop out under a default layout engine.ģ. Click on Graphviz application and then open H-graph, I-graph.dot, which should be in the current R working directory.Ģ. Locate the generated nFCA graphs in dot: H-graph.dot and

These digital H- and I-graph presenations are equivalent to the graphs in Figure 1.ĥ. Digital presentation of the inherent structure results from I-graph:.A member, relationship to another member (relation strength value),.Without '-', it is then in the most outside layer, such as the O above.'-' is 2-depth into the center, such as the Cluster 4.'-' is 1-depth into the center from the outside, such as the Cluster 5 above.Explanation of the presentation above: Each "-" is one depth further into the hierarchical center from the outer most boundary, e.g.Digital presentation of clustering results from H-graph:.The second output includes the following digitized presentation of Hgraph.dot and Igraph.dot (compare them with Figure 1): Opening the Hgraph.dot and Igraph.dot files in Graphviz leadsįigure 1: H-graph on the left panel and I-graph on the right panel "Hgraph.dot and Igraph.dot are generated in the current R working directory" Here is how to use the default "histogram" method and default thresholds to conduct a Where H = "husband", W = "wife", D="daughter", S="son", HM = "husband's mom", W1 = "wife's friend", and o="other", etc. >data("nfca_example", package = "nFCA").

Do not use version 2.28, which has a knownīug. We have tested selected versions of Graphviz. You might already have Ruby in your computer.ĭownloaded from, for visualizing higher-quality nFCA graphs. Output graphs, H and I-graphs are printed out as simple digitized presentations in R, which can be visualized better using Graphiviz outside R.
