I’ll upload the files to the Data folder in the S drive. Narayanaraj kindly provided some example R code that served as the starting point for my research in this project. Push the data into the scoped storage of the sample app: adb push AuroraCOshp/. Open your command prompt and navigate to the folder where you extracted the contents of the data from step 1.
#R FILE TO ARCGIS FILE ZIP FILE#
Running this command will bring up the documentation for that function, usually with examples.ĭr. Extract the contents of the downloaded zip file to disk. A great resource is the help(“f”) function, where f is a function you are trying to use.
#R FILE TO ARCGIS FILE HOW TO#
The most difficult part of this process is learning how to make the various functions work. These operations were accomplished with very little code most of the work is done by the packages and functions already in R, and it’s possible to make your own as well. Now the clusters can be viewed in ArcScene: You’ll want to use the size field rather than a constant value for distance: Run the following command to create a SpatialPointsDataFrame object called shape, which will contain the geometry and attributes of the shapefile: The file.choose command is an alternative to hard-coding a file path and name it will bring up a file selection dialog that you can use to interactively select your file. To read a shapefile, you can use one of the following commands in R, depending on the type of shapefile: Note that Digital Earth uses R 3.0.1, for which spatstat is not available, so some of these commands are not possible in the lab.įor this exercise, we’ll be using the Mount Hood earthquake data (hood3d.shp): You’ll also need the rgl, spatstat, sm, and misc3d packages to run all the commands here.
#R FILE TO ARCGIS FILE INSTALL#
You can install the package in the R gui by selecting Packages>Install Package(s), selecting your mirror site (we have one at USA (OR)), and finding maptools in the list. ', 'The probability of an event is a number between 0 and. This may be pretty basic for those who already have used R, but hopefully it will be a useful introduction for neophytes like myself.Īn easy way to import ESRI shapefile data into R is through the use of the maptools package. myfile open(r'C:\Documents and Settings\user\Documents\probability.txt', 'r') > a myfile.readlines() > print(a) 'Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. This was my first experience using R, and I was surprised at how easy it was (or at least parts of it), though having experience with Python and Java helps. The goal of this project was to use R to run statistical operations on data from ESRI shapefiles, and see about getting the results of these operations back into a format that can be used in ArcGIS.
