In eccc-cdo/SQLTypeR: Preserve R types in SQL

Description

Recompose Recover the original dataframe from the following decomposed representation:

• a dumbed-down version of the dataframe, where logicals are coerced to integers, and factors are coerced to strings.

• a meta dataframe containing the information necessary to recover the logicals and factors in the original dataframe. This operation is reversed by decomposeDF().

Usage

recomposeDF(decomposed)

Arguments

decomposed

A dataframe in decomposed representation: list(data = data, meta = meta).

Examples

df <- tibble::tibble(
  a = factor(c("a", "a", "b"), levels = c("a", "b"), ordered = TRUE),
  b = c(TRUE, TRUE, FALSE),
  c = c(1,2,3)
 )

decomposeDF(df)

recomposeDF(decomposeDF(df))
