Just completed my first social network analysis code(Twitter text data analysis). social networks Scenario The terms can be taken as people and the tweets as groups on LinkedIn, and the term-document matrix can then be taken as the group membership of people. build a network of terms based on their co-occurrence in the same tweets, which is similar with a network of people based on their group memberships. At first, a term-document matrix, termDocMatrix, is loaded into R. After that, it is transformed into a term-term adjacency matrix, based on which a graph is built. plot the graph to show the relationship between frequent terms, and also make the graph more readable by setting colors, font sizes and transparency of vertices and edges. Cool Coding tested aginst with RGui(32bit)
