dbplot_histogram {dbplot} | R Documentation |
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
