Hi all, I'm busy writing a general introduction into programming with R, and I use a lot of examples and tricks that are given in the help list. I have a selection of threads in the help list to use as information for this course. The threads I select must fulfill certain requirements : - they must contain runnable example code that is not too long - the solution must be nice and easy, without being obvious or making use of long apply and eval constructs - the solution should not depend too much on the use of a specific package. - the solution should make optimal use of vectorization in R
Off course I cannot check all messages, so if you run into examples that would make a nice contribution to the course, please feel free to forwa Currently, I am working around following topics, from most likely to be finished to maybe not included : Certainly: - Vectors - matrices - dataframes - lists and other objects - functions - regular expressions - conversion of objects - selecting and replacing of values in objects - merging / splitting objects most likely : - reading in data - working with dates and times likely : - basic statistics applied to vectors/matrices/dataframes/subsets (eg. functions colSums, ave, ...) - models : data selection and input, extraction of output possibly : - generation of output reports in text, latex, html - connections - S3/S4 programming If you have the feeling I'm missing a certain important topic, feel free to let me know. -- Joris Meys Statistical consultant Ghent University Faculty of Bioscience Engineering Department of Applied mathematics, biometrics and process control tel : +32 9 264 59 87 [email protected] ------------------------------- Disclaimer : http://helpdesk.ugent.be/e-maildisclaimer.php _______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-sig-teaching
