Many of my research projects have involved some sort of “flexible” analysis, by which I mean that I either developed a new analytical statistical test, developed a new simulation-based test, or conducted custom simulations to test the sensitivity of our results to some of the assumptions we made. Though the details of all these methods and simulations appear in print, I provide here the computer code necessary to carry them out.

I recommend viewing these files within a code-highlighting text editor, such as Textwrangler (for MacOS) or jEdit (for Windows). Conceptual background can be found in the referenced documents here, with much more detail usually in the supplementary material. Specific details on implementation are found within the function files themselves, including the necessary input, the returned output, and the format of both. In some cases this also means that the way to estimate the maximum likelihood parameter values and confidence bounds are demonstrated via commented sections within the function files. Again, please do ask if you are unfamiliar with this.

#### Misc. phylogenetic functions that I have written for published work

**Test**: There are three functions in this zipped folder. The first two relate to Ornstein-Uhlenbeck models of character evolution along a phylogeny, which I frequently use for my research on phenotypic evolution. The third I wrote in response to plotting ancestral-state estimates for many models – all the different single-line operations are often fine for one figure, but very tedious if you are making many.

*Function 1: Calculating AIC weights.* This simply calculates the AIC weights for various models. It’s simple but I did not find something already written in R.

*Function 2: Producing an OUCH-format data matrix from a standard data frame and a list of internal ancestral states in the ‘phylo’ format.* There are many implementations of the OU model, each with its own strengths. *OUCH* has many advantages but its phylogeny format is distinct from the most commonly used phylogenetic format in R, from the package *ape* (class ‘phylo’). What this means is that if you estimate ancestral states using the R packages *ape* or *phytools* or *diversitree*, those estimates will not be in the same order as the internal node labels in *ouch*. The subsequent manual labeling of internal states that I used to do for *ouch* was time-consuming, tedious, and error-prone when analyzing large trees or posterior distributions of trees, so I wrote this function. It automates that process by producing an *ouch* data frame from a list of internal states (of the discrete “selective regime”) in the node order of class ‘phylo’ and a data frame with continuous data and the tip states for the selective regime.

* Function 3: Plotting ancestral-state estimates for discrete characters, in the form of a pie chart.* This function and its arguments are relatively complicated, but their use is easy to see with examples, which are provided within the function file itself. It should be pretty clear to those that are already familiar with doing this kind of plot.

#### Tests of convergence and history

**Paper**: Moen *et al.* 2016 *Syst. Biol.* 65:146–160. Supp. Mat.

**Test**: In this paper we develop a new test of the importance of a lag time for adaptation for explaining phenotypic diversity among species that inhabit the same environment. The files available at Dryad include the R code and two data files necessary to carry out an example analysis (all detailed as comments within the R function).

#### Code for analyses of convergence, conservatism, and multivariate covariance between morphology and performance

**Paper**: Moen *et al.* 2013 *Proc. R. Soc. Lond. B* 280:20132156. Supp. Mat.

**Test**: These are various functions I wrote for the above paper, including statistical tests we developed specifically for the paper. The zipped folder also has two functions for carrying out a two-block partial least-squares analysis and associated significance tests for axes (as described by Rohlf and Corti 2000 *Syst. Biol.* 49:740–753). Full details, including input format and output of the functions, are found within the function files themselves.

#### Testing whether a regression relationship is stronger than that expected from random sampling

**Paper**: Wiens *et al.* 2011 *Ecology Letters* 14:643–652. Supp. Mat. (starting at line 465)

**Test**: One of the ideas we tested in this paper was whether the range of body sizes found in a community increased with the species richness of the community. Because the range of an unbounded distribution will necessarily increase with sample size, we wanted to test whether the relationship we found was stronger than expected as an artifact of sampling. Thus, I derived a simple simulation in which we constructed random communities and then estimated the regression between body-size range and community species richness for each of these null communities. This formed the sampling-based null distribution for our empirical regression.

#### Test of community assembly

**Paper**: Moen and Wiens 2009 *Evolution* 63:195–214. Supp. Mat.

**Test**: This function is to test whether the phenotypic composition of a community (e.g., in body size) represents a random subset of the source pool, as is often done in community assembly studies. Note that this is an exact likelihood test of what is often approximated through simulation of random community assembly. Our test is based on the hypergeometric probability distribution, a model of sampling without replacement. It allows one to estimate specific “bias” parameters, in effect to estimate which parts of the phenotypic distribution are different in a given community when compared to the source pool.

**Computing environment**: MatLab (this could in principle be converted to R relatively easily – if you are interested, please email me and I will happily do it).

#### Test of the importance of in-situ evolution versus ecologically conservative dispersal

**Paper**: Moen *et al.* 2009 *Evolution* 63:3228–3247. Supp. Mat.

**Test**: In this paper we tested a variety of hypotheses about how phenotypic evolution within a region (on the one hand) and dispersal of species from outside a region (on the other) have affected the phenotypes that we see in communities. One of the tests is simply comparing the relative contribution of these two processes to the phenotypes in a single community. I developed a test to statistically test whether one process was significantly more important than the other. This test is effectively the same as the above test (i.e., based on the hypergeometric probability distribution), but a bit simpler due to only having two categories instead of four. I also conducted simulations to see how the power of this test varied based on the community size.
