Coerce and validate transforms and functions that produce them

as_trans_factory(factory, env = parent.frame())

validate_trans_factory(factory, x = 1:3, y = 1:3)

validate_trans(trans, x = 1:3, y = 1:3)

Arguments

factory: A function that produces a transform object
env: The calling environment, for transform factories that are calls or rlang lambda-style functions.
x: The test x data
y: The test y data
trans: A transform object

Value

The input, invisibly.

Examples

as_trans_factory(age_depth_interpolate)
#> function (x, y) 
#> {
#>     if (!all(is.finite(c(x, y)))) 
#>         stop("Non-finite values in transformation")
#>     verify_length(x, y)
#>     force(x)
#>     force(y)
#>     list(trans = function(new_x) {
#>         stats::approx(x, y, xout = new_x)$y
#>     }, inverse = function(new_y) {
#>         stats::approx(y, x, xout = new_y)$y
#>     })
