ellipse and convex hull fitting package for stable isotope data
Hello developers, I encountered this problem recently when I was learning to use this software. I divided Groups and communities into 6 groups. After drawing the picture, I don’t know...
I'm getting error code: Error in eigen(sigma/c.scale) : infinite or missing values in 'x' when I try to do SEA for more than 4 groups in a single community. Is...
Hi Andrew when we do pairwise comparisons by calculating the proportion of SEAb that differed between 2 groups, to determine if one group is significantly larger than another, is it...
Hi there, I have stable isotope data for several different groups of consumers at three different sites. I plan to use SIBER to produced SEA and layman metrics, to compare...
I'm running some models, (5 chains of 1,000,000 iterations, 500,000 burn-in, 500 thin) and the output of SEA.B is be 10,000 (iterations/thin*chains) rows, instead of the expected 5,000 ((iterations-burn-in)/thin*chains). Is...
Hi Andrew, I hope you are well and thank you for providing many great resources for exploring community interactions. I was recently working with the vector statistics on centroids vignette...
Hi! I have seen some works using NMDS x and y values of individuals to apply in SIBER (Fatty acids research). I have tried this but some things appear to...
When a group is missing from one of the communities, the calculation of the standard ellipse of the mean fails owing to passing of a NA from the group names...
