The purpose of this manual is to assist researchers on methods for data management and analysis using the R environment or other software after data has been collected in the field. The impetus behind this manual was from many years of frustration in trying to analyze data in R using code and forgetting how it was done upon completion of a study. We wanted to find a way to avoid needing to search computers for folders to find old R code then try to remember what we did to the data to get the code to run properly. Over the years, advancements in data handling and manipulation, GIS capabilities, and methods of estimators for home range, movements, resource selection, and spatial epidemiology have occurred within the R environment. Program R is free and used by researchers world-wide but R also provides a platform to create and display spatial layers without the need for the variety of GUI software, free or otherwise. Furthermore, analyzing spatial data in R enables statistical analysis of data without the errors that may arise from bringing data from spreadsheet or GIS software to statistical programs. We would would like to stress that this manual is not the authority on all topics presented herein. Our goal was to create an online manual that could be easily followed by researchers, biologists, or graduate students to analyze their data in R. Although the user would benefit from general introductory knowledge of using R and ArcMap, most of the manual is for mid-level users of R that need quidance beyond the basics of introductory R and GIS courses. We also provide numerous citations throughout each section should the user choose to learn the theory or more details behind each topic. In addition, this manual provides a handy outline of course materials for an Applied Spatial Ecology course that will surely expand or change as the field evolves. As time permits and errors are brought to our attention, we plan to update and correct problems so be sure to send any corrections or comments our way. Any use of trade, firm, or product names is for descriptive purposes only and does not imply endorsement by the U.S. Government.
