Description

This function automatically reshapes long (stacked) raw data from the API (get_data(..., wide = FALSE)) to a wide format where each variable has its own column.

Usage

long2wide(
  data,
  id_cols = intersect(.Tvars, names(data)),
  names_from = "Series",
  values_from = "Value",
  labels_from = if (any(names(data) == "Label")) "Label" else NULL,
  expand.date = FALSE,
  ...
)

labels_from

character. The column containing the labels describing the series.

expand.date
