Dr. Xie is the author of knitr, a package that makes it easy to create well documented R programs where the code and the output are gracefully merged. He created this new package, tinytex, because he felt that the current versions of LaTex had complex installation processes and forced you to choose between a minimal installation that couldn’t do anything useful and a full installation that was bloated with features you’d never use. I can’t say too much about the package yet except that he is right in that it is very easy to install. If I find out more, I’ll let you know. Continue reading
