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.

getMatchingColumns: Filter columns by pattern.
