I am not an exprt on R but to compare the names I extracted to a variable (M) the names of the tree with the tip.tree (M<-mcctree[["tip.label"]])function and then made a matrix with (M<-data.matrix(M)). Then I compared the data of M (the names) with those that comes from the data on a spreadsheet. I hope this helps. Best regards.

In terms of counting how many times a given transformation (e.g. 0->1) has occured, I was wondering if there is a way to generate a histogram if probability distributions for the number of changes based on the joint reconstruction.<br /><br />I have used countSimmap, which returns an integer value for the number of changes, but I'm not sure how this number is calculated from the probability distributions for each node. You mention the possibility of generating histograms in your "Lecture_5.1" on ancestral state reconstructions, but I can't figure out a way of generating such an output.<br /><br />Thanks a lot in advance!Bernardo Santoshttps://www.blogger.com/profile/03700418803879142861noreply@blogger.comtag:blogger.com,1999:blog-8499895524521663926.post-14090363673719754192016-07-10T11:51:27.935-04:002016-07-10T11:51:27.935-04:00This comment has been removed by the author.Unknownhttps://www.blogger.com/profile/03700418803879142861noreply@blogger.comtag:blogger.com,1999:blog-8499895524521663926.post-69859143644207845342016-02-02T16:39:21.369-05:002016-02-02T16:39:21.369-05:00Is there a way to fix specific transition rates in...Is there a way to fix specific transition rates in Q while allowing all others to be estimated at their most likely values?Alexandra R DeCasienhttps://www.blogger.com/profile/06848445703593289579noreply@blogger.comtag:blogger.com,1999:blog-8499895524521663926.post-13376442809601165672014-03-21T09:04:24.896-04:002014-03-21T09:04:24.896-04:00Hello, hope this question goes in the right place ...Hello, hope this question goes in the right place ;) Am I right that from describe.simmap I can get the transition rates simply by dividing the numbers of different transitions by the total number of all transitions?

This is described <a href="http://blog.phytools.org/2013/03/estimating-ancestral-states-when-tips.html" rel="nofollow">here</a>. Basically, x becomes a matrix with n rows and m columns for n taxa and m values for the trait. Each element in the prior probability, Pr(i,j), of the ith taxon being in the jth state. In this case, row names should be tip labels and column names should be state names.<br /><br />Let me know if this is what you needed to know.

I'll obtain the Q matrix as the output of make.simmap (and to use it in sim.history I have to transpose of the printed matrix Q of make.simmap), right? But when I try to run make.simmap I get the following message: "subscript out of bounds". I don't know what I'm doing wrong. The tree is in phylo format and I'm using SYM model. Can you please give me and example of the vector X ("a vector containing the tip states for a discretely valued character") so I can compare with mine? It is a simple vector like x=c("1","1","0","1")? One more question, how can I indicate missing information on the tip states?Elisahttps://www.blogger.com/profile/10826355411884130352noreply@blogger.comtag:blogger.com,1999:blog-8499895524521663926.post-26676870231543167202013-03-17T17:58:53.872-04:002013-03-17T17:58:53.872-04:00If anyone is interested in comparing make.simmap t...If anyone is interested in comparing make.simmap to <a href="http://www.simmap.org" rel="nofollow">SIMMAP</a>, they should check out the phytools function export.as.xml which will create a SIMMAP input file.<br /><br />In my very non-scientific comparison yesterday I found that SIMMAP, under the default conditions for morphology, sampled the same posterior probabilities at nodes as make.simmap - but that the number of changes in SIMMAP were too large (i.e., the 95% distribution did not include the generating number of changes). This might be just a matter of tuning the priors, or it might reflect something deeper. At this point, I just don't know.Liam Revellhttps://www.blogger.com/profile/04314686830842384151noreply@blogger.com
