Twitter follower map

[Yanchang Zhao]

Thanks to the twitterMap() function, it is now very very simple to produce a map of Twitter followers.

See a follower map of @RDataMining at http://www.rdatamining.com/examples/social-meida-analysis, which is produced with two lines of R code below.

> twitterMap("RDataMining", fileName=”twitterMap.pdf”, nMax=1500)

Note that Twitter API requires authentication. You need to follow instructions in "Section 3 - Authentication with OAuth" in the twitteR vignettes on CRAN <http://cran.r-project.org/web/packages/twitteR/vignettes/twitteR.pdf> to complete authentication before running the code above.
