[R] Literature analysis

[Ista Zahn]

I think I my original response was bad. And I also realize that I
don't really understand what you want to do.

Here is what I was thinking:

Format your bibliography as CSV (you can convert common bibliography
formats to .csv using Tellico or similar software). Then read the
references into a data frame:

Refs <- read.csv(textConnection('Title,Entry Type,Author,Bibtex
Key,Book Title,Editor,Organization,Publisher,Address,Edition,Pages,Year,ISBN#,Journal,DOI,Month,Number,How
Published,Chapter,Series,Volume,Cross-Reference,Keywords,URL,Abstract,Notes,ID,Date
Created,Date Modified

(sorry, I know that's going to get all screwed up by word wrapping).
Next split out the keywords into separate columns, and then combine
them again into a value column:

library(ggplot2)
Refs <- as.data.frame(cbind(Refs, colsplit(Refs$Keywords, split="; ",
names="Keyword")))
Refs <- melt(Refs, measure.vars=31:45)

And then that's were I get stuck. I have authors and keywords for each
publication, but I'm not sure how you want this represented.
