Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.

Plotting
organizations <- organization_entity(presidential_debates_2012$dialogue)
plot(organizations)
You can include only entities above a minimum frequency (min = n) as
shown below:
plot(organizations, min = 2)
The user may wish to view the entities alphabetically rather than by
frequency. Use alphabetical = TRUE to accomplish this:
plot(organizations, alphabetical = TRUE)
