dbplot_histogram: Histogram

In dbplot: Simplifies Plotting Data Inside Databases

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

dbplot_bar, dbplot_line , dbplot_raster

Examples

library(ggplot2)
library(dplyr)

# A ggplot histogram with 30 bins
mtcars %>%
  dbplot_histogram(mpg)

# A ggplot histogram with bins of size 10
mtcars %>%
  dbplot_histogram(mpg, binwidth = 10)
