Evaluate an expression while preserving column labels

Snapshots labels from df before evaluating expr, then reapplies them to matching columns in the result. New columns created inside expr receive no label automatically.

Usage

with_labels(df, expr)

Arguments

• df:

  A data frame carrying "label" attributes.

• expr:

  An unquoted expression that transforms df and returns a data frame.

Value

The data frame produced by expr, with original labels restored.
