Testing some nice graphs from R through PluginR in Tiki.

Word-cloud art from mods.t.o

{RR(loadandsave="1", wikisyntax="0", echo="1")}

1. Includes a word cloud with the description of the packages from http://mods.tiki.org
2. Example derived from
3. http://www.r-bloggers.com/celebrating-one-year-of-blogging-with-a-word-cloud/
4. and
5. http://www.sthda.com/english/wiki/word-cloud-generator-in-r-one-killer-function-to-do-everything-you-need

1. In the next line, type should be "url", but since this keyword is blocked through Tiki inside plugin content, we bypass Tiki's check with a paste function - paste0("u", "rl") -, and approving the workaround as admin.

res <- rquery.wordcloud(x=site, type=paste0("u", "rl"), min.freq = 8, max.words = 200,
excludeWords=c("three","main","older","see","done"), colorPalette="Dark2")

1. exclude common words and restrict to words with frequency >= 8, just to get a better picture
