## General Information

Ecologists are generally expected to know a larger range of statistics relative to other fields in biology. However, knowledge of the appropriate statistic test to answer an ecological question can be a major limitation for researchers. This workshop is an introduction to the different methods and statistical approaches to analyzing data in community ecology. The workshop will focus on how to match the available data to possible analyses. I will discuss relevant analyses when there are multiple response varaibles, multiple predictors, and examples of presenting interactions (both statistical and ecological). No prior knowledge is necessary, but some basic understanding of the R environment and community ecology will make the workshop more relevant and useful. The goal of this workshop will be to provide a glossary of potential analyses that will assist understanding and presenting ecological data.

Who: The course is aimed at R beginners to intermediate analysts. Some previous knowledge of R or analyses in community ecology would be useful.

Where: University of Alberta, Edmonton, CW 410 Conference Room, Campus Map

Requirements: Participants should bring a laptop with a Mac, Linux, or Windows operating system (not a tablet, Chromebook, etc.) with administrative privileges. If you want to work along during tutorial, you must have both Git & R studio installed on your own computer (See below for instructions). However, you are still welcome to attend because all examples will be presented via a projector in the classroom.

## Software

#### R

R is a programming language that is especially powerful for data exploration, visualization, and statistical analysis. To interact with R, we use RStudio.

Windows Mac OS X Linux

#### Packages

Please install the LearnCommAnalysis package before attending. This package contains all the datasets, packages, and functions that will be used in the workshop. The package is available through Github and thus must be installed using devtools package. If you do not have devtools, please install that first before running the command below. There are multiple packages that are installed along-side this package. Therefore, the installation can take some time and could be prone to error. Please do this prior to attending to save time and troubleshoot errors. The most common error is that not all dependencies (i.e. packages that are dependent on other packages) were installed. Read the error message, and if this is an issue, install the package that is missing.
