    text
    copied!<p>I'm using R for Social Network Analysis, trying out the packages SNA, Network, and iGraph.</p> <p>My data is a data.frame structured as... <code>d &lt;-</code></p> <pre><code>Source Target Weight Label 1 2 0.5 "Fred" 1 3 0.7 "Fred" 2 3 0.9 "Bill" 3 1 1.0 "Allen" </code></pre> <p>(I also have a version that is just (a) source, target, and weight, and a separate file (b) providing a correspondence between Source IDs and Label values, ie, the names of the sources, where <code>a &lt;-</code> </p> <pre><code>Source Target Weight 1 2 0.5 1 3 0.7 2 3 0.9 3 1 1.0 </code></pre> <p><code>labels1 &lt;-</code> </p> <pre><code>Source Label 1 "Fred" 2 "Bill" 3 "Allen" </code></pre> <p><code>labels2 &lt;-</code> </p> <pre><code>Source Label 1 "TrueName1" 2 "TrueName2" 3 "TrueName3" </code></pre> <p>)</p> <p>I'm working with an Anonymized social network, so I'd like to be able to change the Name labels easily between replottings---ie using label set 1 or label set 2, where the edges are the same, but the node name correspondence between sourceID and Label Name changes. </p> <p>However, when trying to use any of these packages, it seems I would have to convert the values in both source and target to be equal to the labels. Is there any easy way to append labels as a correspondence to source?</p> <p>So long as I have the Label column, things like <code>network(d)</code> and <code>graph.data.frame(d, directed=TRUE)</code> won't work. Once I drop this category, it will, but my graphs have numeric labels.</p> <p>What I'd like to be able to do is something like this:</p> <pre><code>plot(a, labels=NA) plot(a, labels=labels1) </code></pre> <p>and</p> <pre><code>plot(a, labels=labels2) </code></pre> <p>to move between numeric, anonymized, and non-anonymized labels on the graph.</p>
