Description

Conditional on weights being a column, do something like this:

wtpct <- function(x, y) sum(x, na.rm = TRUE) / sum(y, na.rm = TRUE) * 100
datasummary(species * sex + 1 ~ N + flipper_length_mm * Percent(fn = wtpct),
            output = "markdown",
            data = penguins)

Contributor guide

Research direction
Investigate the current implementation of `datasummary balance` in the modelsummary package to understand how weights are used. Look for similar percentage functions in other datasummary functions. Consider modifying the `Percent` function or adding a new argument to support weighted percentages. Review the code in `R/datasummary balance.R` and check the package documentation for custom functions.
