Add by to describe_distribution()

[DominiqueMakowski]

datawizard::describe_distribution(iris, select="Sepal.Width", by="Species")

Would be very convenient

Isn't data_group() enough?

library(datawizard)

iris |> 
  data_group("Species") |> 
  describe_distribution(select="Sepal.Width")
#> # Species=setosa
#> 
#> Variable    | Mean |   SD |  IQR |        Range | Skewness | Kurtosis |  n | n_Missing
#> --------------------------------------------------------------------------------------
#> Sepal.Width | 3.43 | 0.38 | 0.52 | [2.30, 4.40] |     0.04 |     0.95 | 50 |         0
#> 
#> # Species=versicolor
#> 
#> Variable    | Mean |   SD |  IQR |        Range | Skewness | Kurtosis |  n | n_Missing
#> --------------------------------------------------------------------------------------
#> Sepal.Width | 2.77 | 0.31 | 0.50 | [2.00, 3.40] |    -0.36 |    -0.37 | 50 |         0
#> 
#> # Species=virginica
#> 
#> Variable    | Mean |   SD |  IQR |        Range | Skewness | Kurtosis |  n | n_Missing
#> --------------------------------------------------------------------------------------
#> Sepal.Width | 2.97 | 0.32 | 0.40 | [2.20, 3.80] |     0.37 |     0.71 | 50 |         0

Fair, but we have by in a quite a lot of functions now and given the tidyverse's move towards an integrated .by I think it would make sense to support that. Also the output could be a simpler integrated dataframe with a Species column
