How do I get the trait values for the two traits in the paired t-test to match up to their corresponding species in the tree?<br />I am working with a small tree- only 17 taxa- but I can't figure out this step.<br />Sorry- I know this is really entry level stuff, but I could not find instructions for this basic (but critical!) step in any online documentation. <br />Thanks- I am excited to see that this analysis may be possible.

It always takes a value close to the initial lamba settings. Is there a way to deal with this problem? How can I increase number of iterations when lambda is optimised? I have data on 194 speices, so small sample size shouldn't be the problem. My phytools version is 0.5.0.<br /><br />Your help would be much appreciated.<br /><br />Best,<br />AnnaAnna Lestárhttps://www.blogger.com/profile/18225638729445186626noreply@blogger.comtag:blogger.com,1999:blog-8499895524521663926.post-16888177523606656502012-09-03T12:56:05.069-04:002012-09-03T12:56:05.069-04:00Pretty cool little function!

For some of my variables, the results for that function I had are close, but for others they're really different; so I guess I was pretty off. Still, was a good practice. So, once more, thanks!Rafael Maiahttps://www.blogger.com/profile/02395303011366399867noreply@blogger.com
