​​​​Intro to R for Plant Pathologists: Part 1

This webinar version of Part 1 of our workshop will introduce participants to R, using some examples from plant pathology.  Participants will learn how to: use R Studi​o, read data, use scripts, create objects and use logicals, create sequences and vectors, and how to combine everything to create data frames, with some basics on data manipulation, statistical comparisons, and troubleshoot common problems. This is an introductory workshop, so no prior experience in R is needed to be able to participate.  Participants are expected to be able to use their own computer during the workshop, with an up-to-date version of R and RStudio installed.  To follow along in our exercises, participants are recommended to find a location where they can view the webinar on one screen and use another computer screen to run R. A conference room or classroom where you can display the webinar is ideal, although a computer with two screens would also work great.​​​

Dr. Sydney E. Everhart
University of Nebraska

Dr. Sydney Everhart is an Associate​ Professor and Quantitative Ecologist in the Department of Plant Pathology. Dr. Everhart joined UNL in 2014 with a split appointment of research (80%) and teaching (20%), and has established an internationally recognized research program to apply population genetic/genomic approaches to study the epidemiology and evolution of fungal plant pathogens important in the U.S., including Sclerotinia sclerotiorum and Rhizoctonia solani. She currently has an active molecular genetics and computational biology lab group.​

Nikita Gambhir
University of Nebraska

Nikita Gambhir is pursuing her doctorate degree in Plant Pathology at the University of Nebraska-Lincoln. Her research is focused on understanding the evolution of fungicide resistance in Sclerotinia sclerotiorum and Rhizoctonia zeae. Broadly, she wants to decode the dimensions of pathogen evolution, which could significantly improve disease management. Apart from research, Nikita enjoys teaching and has co-taught several workshops on​ the statistical software R at the regional, national, and international platforms.

Katie Gold
Cornell University

Dr. Gold is a newly appointed Assistant Professor of Grape Disease Ecology and Epidemiology at Cornell University where she holds the primary research and extension responsibilities for grape disease management for NY state. Gold holds a visiting faculty fellowship at the Jet Propulsion Laboratory and is an international expert on plant disease remote se​nsing. Gold’s research combines precision agriculture, remote sen​sing, data science, and fundamental plant pathology to develop innovative disease detection and management tools that support the profitability and sustainability of stakeholders. Her research primarily focuses on the development in-situ and imaging spectroscopy for the detection, differentiation, and monitoring of disease in specialty crops.​
