Calculate little deltas from abundance ratios — little

For all intensities $i$, $$\delta_i = (R_i / R_iwg - 1) \times 1000$$

little_deltas(.data, ..., quiet = NULL)

Arguments

.data: A tibble with abundance ratios.
...: These dots are for future extensions and must be empty.
quiet: If TRUE, print info messages. If NULL (default) listens to options(clumpedr.quiet)

Value

Same as .data but with new columns d45-d49.

Examples

# generate some artificial data to show how it works
x <- function() rnorm(n = 10)
dat <- tibble::tibble(R45 = x(), R46 = x(), R47 = x(), R48 = x(), R49 = x(),
                      R45_wg = x(), R46_wg = x(), R47_wg = x(), R48_wg = x(), R49_wg = x())
dat <- dat |>
   little_deltas()
