Hi all, I'm currently working through "The Analysis of Time Series" by Chris Chatfield. In order to also get a better understanding of R, I play around with the examples and Exercises (no homework or assignement, just selfstudy!!). Exercise 2.1 gives the following dataset (sales figures for 4 week intervals): > sales2.1.dataframe 1995 1996 1997 1998 1 153 133 145 111 2

Warranty on Accuracy, Precision, Legality, ... of R in Research (These questions may well have been raised.) What is the implied warranty of using R for research & publications, consulting, etc.? Alternately, how does one obtain such a warranty? Your answers will be much appreciated. Perhaps you can point me to some websites which discussed this subject in the past. Thanks & regards
