The purpose of the training workshop is to give users a hands-on, interactive introduction to the R analysis platform, the SWMPr package for R, the widgets of SWMPrats, and selected time series topics.

The morning session will cover the basics of R and SWMPr. R is a data analysis software and programming language and SWMPr is an R package designed for working with SWMP data.

The afternoon session will be an overview of the widgets of SWMPrats and selected time series topics. The SWMPrats website was created to assist the NERRS program with analysis and interpretation of SWMP data. Three widgets on the website allow users to summarize trends within and between sites using a point-and-click approach. Selected time series topics will include weighted regression for trend analysis, time series decomposition, and Seasonal Kendall tests.

Both sessions will prepare users to better navigate R software for tackling SWMP analysis problems. You will finish the workshop with a working knowledge of data import, processing, basic plotting, basic analysis, and interpretation of results.
