All, I have just uploaded a new version of my introductory notes to R to: http://www.myatt.demon.co.uk This version add some more on graphical functions (use of par(), plots with error bars &c.) as well as a section on data management covering functions such as merge(), data.frame(), as.factor(), as.numeric(), cut(), levels(). I think that this is about as far as I can go with this document so once I get feedback from some of you out there I will finalise the document and upload it to CRAN. So once again ... all reports of problems, suggestions, &c. Gratefully received. Best wishes, Mark -- Mark Myatt -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
