Hello world, I am actually transferring a course in data management for students in biology, geography and agriculture from statistica to R - it works surprisingly well. If anyone is interested in my scratch/notepad (in German language), please see www.hydrology.uni-kiel.de/~schorsch/statistik/statistik_datenauswertung.pdf (pages 40-52) The dataset is: www.hydrology.uni-kiel.de/~schorsch/statistik/erle_stat.csv It contains a 10 year dataset.

Hello, For not too regular users of R, preparing the data is somehow a burden. Comming from iMacro in FireFox I get a badly designed csv, which I need to put into a daily R script.

Hello, Collecting data I need to check in a mysql server. As the data are dependent on each other I have to filter first. However, I have now the problem that I find a value and would like to insert it into a data query for the "real select" command.
