Materialize one weather transform

Source: R/class-weather.R
materialize_weather.Rd

Applies a named transform to a weather object and returns the DERIVED weather object – the same clone interpolation creates when a link selects that transform. For inspection and reporting; the input object is not modified.

Usage

materialize_weather(weather, transform, ...)

Arguments

weather

a weather object.

transform

single character, the transform name; resolved weather@misc$transform -> session registry -> built-ins.

...

arguments forwarded to the transform function (what a link row's parameter columns would carry).

Value

a weather object named <WEATHER>_<transform> whose wval (and defVal) carry the transformed series; misc$transform_source records the provenance.

Examples

w <- newWeather("W_SPEED", weather = data.frame(
  timeslice = c("s1", "s2"), wval = c(4, 12)))
w@misc$transform <- list(AF = function(weather, ...) pmin(weather / 10, 1))
materialize_weather(w, "AF")@weather
#>   cluster region year timeslice wval
#> 1    <NA>   <NA>   NA        s1  0.4
#> 2    <NA>   <NA>   NA        s2  1.0
