R-scripts-for-spatial-data-processing

I am collecting here simple R scripts for processing and analysis of spatial data. Mostly very basic stuff that I have found useful on a regular basis.

This is a work in progress, any comments and suggestions are welcome!

Reading and writing spatial data in R

1. [Reading shapefiles] (/ReadingDataIntoR/readShapefile.R)
2. Reading coordinate information from text files (coming up..)
3. Writing shapefiles (coming up..)
4. [Getting data from MS Access database] (ReadingDataIntoR/GetDataFromMSAccess.R)
5. Getting data from PostgreSQL database (coming up..)

Data processing and spatial analysis in R

1. [Point-in-polygon: join attributes from polygons to points] (SpatialAnalysis/PointInPolygon.R)

Map visualizations in R

1. [Plot points on a simple world map] (Visualization/PlotPointsOnAMap_rworldmap.R)
2. [Plot points on google maps] (Visualization/PlotPointsOnAMap_ggmap.R)

Geotagged Social Media Data in R

1. Getting tweets (no code here yet)
2. [Plot points on google maps] (Visualization/PlotPointsOnAMap_ggmap.R) or [Plot points on a simple world map] (Visualization/PlotPointsOnAMap_rworldmap.R)
3. [Plotting wordclouds] (TextMining/PlotWordClouds.R)
4. [Most frequent words] (TextMining/WordFrequencies_top10.R)
