6/13/2016

Our summer R gatherings are entering their 3rd week.  We meet Tuesdays, 9-11:00am in SEC 2438.  To recap, here is what we did so far:
  • file manipulation with dplyr and tidyr: here.
  • simple regression and diagnostics of (most) of the assumptions:  here.
This week, we will be learning about using some of the spatial tools R has, so that we have less of a need for ArcMap.  The topics will include
1) Map making:  Shapefiles - points/polygons (different symbol/coler levels), Rasters, Inset Maps, Map necessities (Legends, north arrow, scale, text identifiers)
2) Data Management:  Cropping, Masking, Filtering, Convert Files (e.g., points to polygons, Minimum convex polys), Random points in a grid (sampling design)
and we might have time for...
3) Analyses: Buffer points, Distance between points/polys (nearest distance), Interpolations, Overlay/Extract, Spatial autocorrelation, Mean center/weighted

Notes for week three here.
