Dear Axel Since you are using princomp (among other things) you might find the biplot function useful on the output of princomp. I have not studies your code in detail but you do seem to be doing several things in multiple ways using functions from different sources. I wonder whether it mig

Hi Axel, It seems to me that cluster analysis could be what you are seeking. Identify the clusters of different combinations of fatty acids in the oils. Do they correspond to location? If so, is there a method to predict the cluster membership of a new set of measurements? Have a look at the cluste

Hi Mike, The book makes use of .csv files, which are provided, along with all R code and .RData files. You have an interesting thought about people pulling data from diverse sources and making everyday use of R. For this, I would suggest using Excel or Google Docs Spreadsheets to compile and o

Rainfall data is widely accepted as Random walk process and hence it is non-stationary. Therefore if correlation or regression coef. is measured on raw data then you may land in the world of spurious measures. I would suggest you to check whether unit root is there in your data or not first. If it
