Re: [R-sig-eco] EstimateR and Chao 1 standard deviation

Hello again, Thanks Bob for your prompt response to my silly question. Apart from ignoring your work, I was overlooking that the variance expression computed by estimateR is the "classic" expression in appendix B on EstimateS web page, while I was trying to compute the bias-corrected one. That t

Dear Luis, 1) Have a look at the multcomp package for the multiple comparisons. You will have to define the relevant contrasts manually. 2) reorder() will help you. reorder(C$Comportamiento, C$Conteo, FUN = mean) Best regards, ir. Thierry Onkelinx Instituut voor natuur- en bosonderzoek / Resea
