Dear list, there are two datasets: the data "geo" is a geodata-set including, "data", covariates and coordinates. The second dataset "fehlcord" is a dataset including 2 columns for the coordinates and additional columns for covariates. I want to use...

Dear Emmanuel, Thanks a lot for your response. I, however, do not think the full model (i.e. "*" instead of "+") is the issue here, since I tried with the simplified model before and it rendered the same error message as...

Dear ?kos, I tried it on a small partition of my data. However, the processing time is the same :(. Any other suggestion? ------------------------- Sara Shaeri KarimiPhD Candidate, Department of Environmental SciencesFaculty of Science and EngineeringMacquarie University, NSW 2109 Australia?

Dear Ben This is what the summary(M_bud_type0) says. As expected, there are plenty of NAs in the interactions between (uncrossed) levels of the interaction between the nested factors (fBud_type:Species): Call: glm(formula = Dead ~ Treatment * fBud...

Dear Ben, Thanks for your response. I had read a very similar response to FAQs explaining why the error relates to rank deficient models. I have tried to center Treatment (a continuous variable, sorry I didn't specify this!) but...

Dear All, I have question concerning the unit of measurement for the range parameter in the fit.stvariogram in gstat, i have fitted the following spatio temporal variogram for data on monthly averages pf pm10 and the longitude and latitude...

Dear Thierry, Many thanks for your reply. You are totally right (I should have checked my notes more carefully before posting this question...). Thanks for the clarification! Sara Fraixedas Doctoral Student The Helsinki Lab of Ornithology (HelLO) Finnish Museum of...

Hi David et al, Thanks for your help. I spent the afternoon and thought that would work but then I realized it was giving a different answer. I have counts ('hits') in each grid cell, and have then calculated the...

Dear all, I am trying to implement a mixed model that takes into account the repeated measure design of my study. My study consists of a 2 parts ("part 1" and "part 2") x 2 takes ("take 1" and "take...

You are right! This is weird since when I check the data table "species" I can see values of the variable Bud_type for both species... Vu has "sc" and Vv has "hy"... Then, if I follow your suggestion and...

Dear Prof. Pebesma, Thanks for reply I will try to make it more clear the coordinates are converted to decimal degree format using the equation DD = d + (min/60) + (sec/3600) and then projected using > llCRS <- CRS("+proj=longlat +ellps...

Hi Ben Thanks for the info and suggestions. My Bayesian background is using JAGS and therefore the notation of MCMCglmm still confuses me. My second question was about the random argument in MCMCglmm, where both random = ~us(trait):animal and...

Dear List Members, I do not know how to specify a nested structure of fixed factors in glmer. All the previous help messages I have found about nested factors in lme4 relate to ?random? factors, but I need my ?fixed...

Hi Emmanuel, Yes, I have the same problem when using treatment + Bud_type. And yes, I produced a contingency table for each species... My conclusion is that glmer can not handle designs with nested fixed factors since it is not...

Hi, I am using ggplot2 and geometric points. I am trying to create a plot with 3 different panels, one for each time period, I want the size of the points to be a function of the value in column...

Dear Jarrod (and list) I am trying to run generalized mixed effects models where (i) the dependent variable is a non-ordinal 4-level category (ii) I have to control for phylogeny using a rooted, non ultrametric phylo object with...

Below you can see the contingency table for Treatment*Bud_type with the observations in each combination. As you can see the design is not balanced but there are no combinations with particularly few observations. I have checked this table...
