**Note - For every course we have implemented live stream remote attendance .  You will need a computer and an internet connection.  

This course is designed for participants who wish to gain beginning to intermediate skills in using R for manipulating, visualizing and analyzing their environmental or ecological data.  R is a comprehensive statistical programming language that is cooperatively developed on the Internet as an open source project. This freely available statistical package R is a powerful tool and is projected to become the most widely used statistical software.

This class uses datasets complete with errors you get practice taking real field data into R, through hands-on using instructor-led examples. It is applicable to anyone that conducts environmental monitoring or uses environmental or ecological data for research, management, or policy-making and is recommended for anyone needing to become proficient with R basics.  Being proficient in R will help participants be competitive in their chosen fields.

"Provided a solid foundation yet linkages to allow one to delve deeper into more advanced topics." C. Lynch, October 2013

"Very good introduction to R, gained familiarity with data types and data manipulation." B. McGuire, October, 2013

"Provided a lot of information covering how to do many things in R.  the book will serve as a good tool using R in the future." P. Kusnierz, October, 2013

"There were excellent course materials.  I will be using the manual as a reference for along time to come." T. Kantz,  September, 2013

"Hands-on learning; great instructor who knows the subject and the data; excellent camaraderie among the students." T. Kahler, September, 2013


After completing this course attendees will be able to:

  • Understand the uses of R for working with environmental or ecological data
  • Installing R and R libraries
  • Import and export data from Excel
  • Sorting, merging, and aggregating, subsetting, and converting data
  • Query and display data and generate basic data summaries
  • Create a variety of high quality data visualization graphics
  • Perform common statistical tests including t-tests, ANOVA, and  linear models
  • Develop basic scripts to automate and document procedures and analyses

Please note that attendees will need to have a laptop to class with the R software program. Instructions on how to download the program will be emailed out prior to the class. Installations must be completed prior to class - please contact us if you are having problems.

*Reduced tuition is available for Native American tribes, government employees, nonprofits, students and AFS, NAEP, NEBC, TAEP members.

About the Instructor

Kevin Ceder

Kevin Ceder


Kevin Ceder is an Ecosystems Analyst with Cramer Fish Sciences. Kevin has 10 years experience using quantitative methods to support data-driven, integrated resource management, planning and assessment. He excels in developing tools that reduce complex processes to easy-to-use and easy-to-understand systems for decision-makers. Kevin has over 10 years of experience using R as his primary data management and analysis tool and excels in providing R programming solutions.  He has provided R training and coaching to a diverse clientele.

With CFS, he is a lead environmental statistician, helping clients visualize the complex relationships between land management activities and the affected environment.  Kevin's focus is on analysis and modeling of forest ecosystems to help stakeholders understand the influence management activities can have on terrestrial and aquatic habitat—and ultimately their influence on salmon and trout. He combines doctoral-level understanding of ecosystem processes with expert tool-building skills to lead the development of integrated mathematical simulation models. 

Kevin offers expertise in numerous areas—growth, development and management of forest stands; ecosystem data compilation and analysis; forest and population simulation model development and use; ecosystem assessment model development and use; spatial analysis and cartography; and software development to create integrated tools. 

Prior to joining Cramer, Kevin spent 15 years as a biometrician and was involved in many projects to evaluate the effects of forest growth and management on ecosystem outputs. Kevin provided simulations for numerous assessment projects in Washington and Oregon, evaluating everything from harvest volume and carbon sequestration to fire risk and wildlife habitat.

Kevin received his B.S. and M.S. degrees in forest management and silviculture from the University of Washington where he is currently a doctoral candidate in forest biometrics. He has worked for several research cooperatives to develop mathematical simulation models addressing growth and yield of young managed forests, wildlife habitat management, and wildfire risk assessment.
