Description Usage Arguments See Also Examples
Uses very generic dplyr code to aggregate data and then 'ggplot2' to create the histogram. Because of this approach, the calculations automatically run inside the database if 'data' has a database or sparklyr connection. The 'class()' of such tables in R are: tbl_sql, tbl_dbi, tbl_spark
