question concerning nmds.min
In the next update of ecodist, nmds.min() will return the stress and r2 for the selected configuration. Thanks for the suggestion. Sarah 2012/2/2 Gian Maria Niccol? Benucci <gian.benucci at gmail.com>:
Thank you, you were of great help. Cheers, G. 2012/2/2 Sarah Goslee <sarah.goslee at gmail.com>
Are you using ecodist? If so, you need to look at iris.nmds to get the stress and the r2. min(iris.nmds$stress) iris.nmds$r2[which.min(iris.nmds$stress)] The advantage of nmds.min() is that it lets you choose a particular dimension solution rather than the lowest available. For your example, the same thing can be achieved with iris.nmds$conf[[which.min(iris.nmds$stress)]] Sarah
