After posting so many entries about typos in my books (making you wonder how there could be any text left!) and postponing their classification for so long, I decided on Saturday afternoon to collect those entries into a comprehensive pdf document that should be more useful for readers. I incidentally noticed that my book web-page had not been updated for the publication of Méthodes de Monte-Carlo avec R two months ago and did update it… I am obviously more than grateful to all those who contacted me, either thru the Og or by email to point out those numerous typos. As the Wheel had started rolling (or weaving), I took the opportunity to clean the original LaTeX files as well, including Introducing Monte Carlo methods with R. Since this is a print-on-demand edition, the changes should be immediate.
