Our February meetup will have 2 components. Mary Anne Thygesen will provide an introduction to R. Additionally, Alan Campbell will share an interesting project he has been working on, involving monitoring soil data at vineyards in the north Willamette valley. See below for more information on both presentations.
Pizza will be provided by Alan!
Introduction to R
Presented by Mary Anne Thygesen: instructor, speaker and researcher
Start the New Year with R. Bring your computer and a data set that you would like to work on. First we will get R loaded on your computer, up and running. Then we will work on getting data into R. Followed by a brief overview of what you can do with R. A list of resources including books, and online courses will be included. If possible, please try to install R on your laptop beforehand! (many simultaneous downloads may congest our host's WiFi).
Connecting Vineyards to the Internet
Presented by Alan Campbell: plant physiologist working as a consultant in the Oregon vineyard industry.
This past year, Alan installed 54 soil tension sensors in the root zone of grapevines in 18 locations in 6 vineyards in the north Willamette Valley. The soil sensors, and additional air temperature and humidity sensors, were monitored through a wireless data network, with readings uploaded every 15 minutes to an online database. At the end of this season, there are over 10,000 data points from each of 90 sensors, or nearly one million data points in all. Talk will give an overview of what was done, the structure of the data, and of the kinds of questions that time series analysis (etc) with R might answer. Alan is interested in analyzing temporal correlations in last year's data, and preparing for the analysis of similar data in greater volume in the years ahead.
