R package for community ecologists: popular ordination methods, ecological null models & diversity analysis
Hi, I am plotting some RDA of morphological data against some experimental treatments in vegan. The morphological data is continous and the explanatory variables are continuous and categorical. I got...
### hope this is appropriate ### CONTEXT I use the function rda() to analyse morpho-ecological correlations; having morphological (shapes variables coming from geometric morphometrics) and ecological (10 variables, ordinal or...
Anderson et al (2017: [doi: 10.1111/anzs.12176](https://doi.org/10.1111/anzs.12176)) have proposed a modification to the pseudo F statistic in PERMANOVA that accounts for group heterogeneity. The modified F is: ...
Hello! I am trying to perform PERMANOVA on a Jensen-Shannon divergence matrix calculated from normalized data (clr and tss) and getting this error (title). When I use non-normalized data, the...
Hi, I have a table of OTU's and how many times they were seen on each media:  I used the code written below and got strange results. The statistical...
Hi, I am interested in running PERMANOVA on continuous variables. I would like to know if I can find the formula used to calculate the statistic. Is there a specific...
Hello Vegan R Package Team, I design hexagon R package logos and decided to just make one for your package. My name is Zane Dax and have designed 2 R...
Hi! I'm really lost because I have read very different things of the same topic. I have a continous variable of interest (X), but also factors that I think they...
Hi, I used `adonis2` with the following code `adonis2(df_pathway_f~., bgc_exp_f, permutations = 999, distance = 'bray', by = "margin")` But I got the error `need larger value of 'ncol' as...
Dear, For my study, I have repeated measurements and I want to account for this in the adonis function using the strata() function. I have either 2, 3 or 4...
