dbplot (version 0.3.3)

dbplot_histogram: Histogram

Description

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

Usage

dbplot_histogram(data, x, bins = 30, binwidth = NULL)

Arguments

data

A table (tbl)

x

A continuous variable

bins

Number of bins. Defaults to 30.

binwidth

Single value that sets the side of the bins, it overrides bins
