Title: "Find nearest neighbors between two datasets based on longitude and latitude coordinates using R and Python" The customer's task: "I need to find the closest 5 addresses (based on longitude and latitude) in set B for each address in A. I then need the addresses in A with their 5 closest matches in B plotted in a google maps graph. All addresses are in Germany. At the end of the project I would like to receive the code in R/or Python together with some comments within the code so I can use it on my own in similar situations." Milestones: The first milestone (R language): find the closest 5 addresses, based on longitude and latitude in set B for each address in A); The second milestone (Python): create the google maps graph.

Election commission of publishes list of voters in a pdf format. We created the program to convert these pdfs to csv. It has voter details such as ID, Name, Father or Husband name, Age, Gender and address .. All arranged as a small square table. In a given page it will have 3 columns and probably 10 to 15 rows. So total 40 or 50 voters per page.

Rcpp script to intersect convex polygons using boost::geometry::intersection() An R script: polygonTestScript.R First the script builds the polygons as R matrices. Each polygon is stored as a set of xy-coordinates that define the boundary of the convex polygon. The x-coordinates are the first column in the matrix and the y-coordinates are the second column. The set of polygons is then stored in two different R lists. One of the lists is what will be read by the Rcpp/Cpp script. Two lists are created in order to allow you to test the script with different scenarios. The R script also contains some ggplot2 code that will allow you to plot the polygons. Lastly there are two calls to the findIntersections() function. These calls will allow you test the code using the two different lists of polygons that were created at the beginning of the R script.
