Panel-safe binary operation on aligned wide panels

Description

Applies an elementwise binary operator to two date-aligned wide panels (first column Date, other columns are symbols), preserving the Date column and a consistent symbol set. Supports intersection or union of column sets; missing entries introduced by how="union" are filled.

Usage

ml_panel_op(A, B, op = `*`, how = c("intersect", "union"), fill = NA_real_)

Arguments

A, B	Data frames with a Date column and one column per symbol.
op	Binary function to apply elementwise (e.g., *, /, +).
how	Character; "intersect" (default) or "union" for the set of symbol columns to operate on.
fill	Numeric; value used to fill gaps when how="union".

Value

A data.frame with Date and the operated symbol columns.

Examples

## Not run: 
out <- ml_panel_op(mom12_panel, vol_panel, op = `*`)

## End(Not run)
