Dear all, I am a beginner with R (and also with the statistics) for which I hope to be clear. I should do this non-parametric test on data I extracted from maps. In practice I have a column that represents the landscape Dynamics of a certain time period (there are 3 dynamics, each of them marked by the number 1, 2 or 3) and the other column with the values of a topographic variable (for example the slope) . In all, there are more than 90,000 pairs of values. Going to do the test in R, for all the dynamics and for all the variables, I get out of the values of chi-square elevated (even in the order of thousands) and a p-value always <2.2e-16 .... why? Where can the error be? in the script or in the test approach? Thanks in advance
