My sample size is 147 not either 9 or 7 in any case. I agree that the computer displays these numbers! don't know why?

Nevertheless, in this analysis the number of specimens (dependent shape variable) is 147, obviously, with the equal number of observations for each independent variables (here, we used two factors ind$Stages and ind$Location ). It is interesting to note that I am getting good results using single factor Manova; dependent shape variable over, either ind$stages or ind$location, at a given time, though with/without interactions as well. Even, it works fine with more factors if I model without any effect of interaction, and the results are given below > Paint<-procD.lm(coords ~ Csize + ind$Stages + ind$Location, data = > Paintgeo147, iter = 9999, RRPP = FALSE, print.progress = FALSE, int.first = > FALSE) > Paint3factor Call: procD.lm(f1 = coords ~ Csize + ind$Stages + ind$Location, iter = 9999, RRPP = FALSE, int.first = FALSE, data = Paintgeo147, print.progress = FALSE) Type I (Sequential) Sums of Squares and Cross-products Randomization of Raw Values used 10000 Permutations Df SS MS Rsq F Z Pr(>F) Csize 1 0.04688 0.046880 0.064257 13.4431 7.9867 1e-04 *** ind$Stages 4 0.17575 0.043938 0.240899 12.5994 8.3726 1e-04 *** ind$Location 1 0.01871 0.018713 0.025650 5.3662 3.2145 0.0042 ** Residuals 140 0.48822 0.003487 Total 146 0.72956 --- Signif. codes: 0 ‘***’ 0.001 ‘**’ 0.01 ‘*’ 0.05 ‘.’ 0.1 ‘ ’ 1 The main issue, here, is that somehow I don’t know how to use the proper command to quantify effects of interaction, say for example ind$Stages: ind$Location, Csize: ind$Stages, Csize: ind$Locations... etc. ???? Thanks for spending your time and effort!
