Downcast integerish columns to integer

Iterates over all columns (or list elements) in dataset and converts any non-logical column whose values can all be represented as integers without losing any information to integers. Columns that contain non-integerish data are left unchanged.

Usage

finalize_integers(dataset)

Arguments

dataset

(data.frame, list, or NULL) The dataset to process.

Value

The dataset with all integerish columns converted to integer (or NULL if dataset is NULL).

Examples

df <- data.frame(x = c(1.0, 2.0, 3.0), y = c(1.1, 2.2, 3.3))
finalize_integers(df)
#>   x   y
#> 1 1 1.1
#> 2 2 2.2
#> 3 3 3.3
