Compute a Climate Index by Name — ck

A generic dispatcher that calls the appropriate ck_* function based on a string index name. Useful for programmatic workflows where the index is selected at runtime.

Usage

ck_compute(data, index, ...)

Arguments

data: A named list or data frame containing the required input vectors. Column names should match function argument names (e.g. tmin, tmax, precip, dates).
index: Character. Name of the index to compute (e.g. "frost_days"). Use ck_available() to see valid names.
...: Additional arguments passed to the underlying function (e.g. period, threshold, base).

Value

A data frame as returned by the underlying ck_* function.

Examples

d <- data.frame(
  dates = as.Date("2024-01-01") + 0:9,
  tmin = c(-2, 3, -1, 5, -3, 0, 2, -4, 1, -1)
)
ck_compute(d, "frost_days")
#>       period value      index unit
#> 1 2024-01-01     5 frost_days days
