Does R have a function to calculate Bray-Curtis distance measures, which is probably one of the most frequently used and recommended dissimilarity measures in ecology? It isn't mentioned in dist().

G'day, The following code gives a two-way factorial anova, which is completely balanced. However when model.tables is called, the response is: "Design is unbalanced - use se.contrasts for se's", and SEs are not available. Why doesn...

Hi meta-analysts, I would like to calculate SMD from fitted models. I have datasets that have various idiosyncrasies, such as variable sampling effort or repeated measures, which should be accounted for before calculating effect sizes. Is there a way...

Hi meta-analysts, I'm working on a meta-analysis of data from the 2019-20 megafires in Australia. I am getting an effect size using SMCC where the same sites were surveyed before and after fire. I use SMD...

G'day, Plot doesn't seem to work when I specify block as an error term, but does if I load block into the model as the first factor (see code below). Is there some way to make plot work...

R, I want to get means and confidence limits on the original scale for the treatment effect after running a mixed model. The data are: response<-c(16,4,5,8,41,45,10,15,11,3,1,64,41...

G'day, I'm fitting a simple one-way nested anova and would like to obtain standard errors or confidence limits. I'm using se.contrast to try to get se for the contrast between the two levels of the...
