Histogram

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

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)
