The presented paper describes the design and implementation of R functions for twitter feeds analysis and visualization based on a combination of analytical technologies with big data processing tools. The main idea was to utilize the Hadoop processing framework and its storage and computational capabilities in analytical tasks designed and implemented in R language. For such purposes, we decided to use the Hadoop HDFS and MapReduce v2 for storage and handling of the processing logic connected via Tessera framework to analytical functions written in R. The results of the analysis were presented as the graph visualizations. Visualizations were implemented using the Trelliscope framework for flexible visualizations of large complex data in R environment in fast and effective fashion.
