Uses dplyr operations 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
Fixed width for each bin, in the same units as the data. Overrides bins when specified
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)
