igraph and structured text exploration
From the post:
I am in the slow process of developing a package to bridge structured text formats (i.e. classroom transcripts) with the tons of great R packages that visualize and analyze quantitative data (If you care to play with a rough build of this package (qdap) see: https://github.com/trinker/qdap). One of the packages qdap will bridge to is igraph.
A while back I came across a blog post on igraph and word statistics (LINK). It inspired me to learn a little bit about graphing and the igraph package and provided a nice intro to learn. As I play with this terrific package I feel it is my duty to share my experiences with others who are just starting out with igraph as well. The following post is a script and the plots created with a word frequency matrix (similar to a term document matrix from the tm package) and igraph:
A very nice introduction to the use of igraph for exploring texts.
