toaster (version 0.2.5)

analytics and visualization with Aster Database

Description

toaster (a.k.a 'to Aster') is a set of tools to perform in-database analytics with Teradata Aster Discovery Platform. toaster embraces simple approach by dividing tasks into 2 steps: compute in Aster - visualize and analyze in R. toaster `compute` functions use distributed, highly scalable, parallel SQL and map-reduce for processing of large data sets in Aster database. Then `create` functions visualize results with boxplots, scatterplots, histograms, heatmaps, word clouds, maps, or slope graphs. Advanced options such as faceting, coloring, labeling, and others are supported with most plots.
