Re: [R-sig-eco] How to set Manually the Reference Level in glmmTMB

Dear Alexandre, You could change the formula to reproducao_bin ~ 0 + Grupos_Finais + ano_medida + Basal_Area_m2*Grupos_Finais + R_dens_total*Grupos_Finais + (1|numero) + (1|bloco/transecto/parcela) Another option is to calculate contrasts based on the model. Best regards, ir. Thierry Onkelinx

Re: [R-sig-eco] LEVELS function NULL

Notice that the levels are ordered alphabetically. Use factor() and it level argument to get them in a more sensible order. Best regards, ir. Thierry Onkelinx Statisticus / Statistician Vlaamse Overheid / Government of Flanders INSTITUUT VOOR NATUUR- EN BOSONDERZOEK / RESEARCH INSTITUTE

Re: [R-sig-eco] Ecological datasets for teaching statistics

Dear Manuel, Our institute has published 54 datasets under an open data licence at GBIF ( https://www.gbif.org/dataset/search?publishing_org=1cd669d0-80ea-11de-a9d0-f1765f95f18b ) You can look for local data on GBIF too. Best regards, ir. Thierry Onkelinx Statisticus / Statistician Vlaamse

. Is it a pool level or a smaller section of the pool. Do you have coordinates of the sampling locations of both zooplankton and the birds? Best regards, Thierry ir. Thierry Onkelinx Instituut voor natuur- en bosonderzoek / Research Institute for Nature and Forest team Biometrie & Kwaliteits

Re: [R-sig-eco] help

Dear Baoping, You could standardize the weight by stage. That would remove the confounding between weight and stage. Best regards, ir. Thierry Onkelinx Instituut voor natuur- en bosonderzoek / Research Institute for Nature and Forest team Biometrie & Kwaliteitszorg / team Biometrics &

Re: [R-sig-eco] best choice of GLMM for seed set data

Dear Mehdi, Assuming that you want to model the probability of germination, yes. Note that cbind(seed, 100) is WRONG syntax. CORRECT syntax: cbind(n_success, n_failure) Have you tried anova(your.model)? Best regards, ir. Thierry Onkelinx Instituut voor natuur- en bosonderzoek / Research

Re: [R-sig-eco] best choice of GLMM for seed set data

, then I'd rather see it as counts and use a Poisson or negative binomial. The correct syntax in the binomial case is cbind(success, failure). Or in your case cbind(seeds, 4 - seeds).
