How to visualize the resulting graphs using Graphviz 5.1 Use Graphviz in a Window's machineġ. These digital H- and I-graph presenations are equivalent to the graphs in Figure 1.ĥ.
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").Just install Ruby quickly and run above commands again.Ĭonsider the build-in example, about relationships among a family and the family with their extended family, friends and others. If you do not have Ruby, you will get a warning message.

How to install, load and unload the package nFCA in R The detailed instructions for using Graphviz in PC/Mac/Macports/Linux are givenĢ. 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. Ruby program implementing the faster concept analysis algorithm.
