R is increasingly becoming the software package of choice for manipulating, analyzing, and presenting data in ecological studies. This 2-credit graduate course will focus on fundamentals of the R language and introduce students to particular packages that are useful across a broad set of ecological applications. This course will emphasize tools for inputting, editing, checking, restructuring, and plotting of various data types (time series, counts, geographic layers, model output). This course will also include some discussion of general statistical approaches (hypothesis testing, parameter estimation and model selection) and their proper execution in R.
