This 3-hour workshop introduces the precision agriculture enthusiasts to the popular open source R software to handle various sources of data acquired for characterizing field heterogeneity. The RStudio interface and numerous packages for organizing, manipulating and exploring data will be presented to the workshop participants. Formation of R scripts for standard statistical and geo-statistical analysis will be demonstrated to interpret and extract information. With a series of hand-on activities, the participants will obtain practical techniques such as sensor data cleaning and filtering, local pedotransformation functions, spatial interpolation, prescription mapping for site-specific management.
