arrange_isobole: Arrange the isobole more robustly

In IntiQuan/populationIsoboles: Calculate isoboles efficiently

Description

Call arrange_isobole_internal in multiple ways to be a bit more robust. Use either different metric or a different scale. For all scale trafos, reverse them at the end to get the original isobole back

Usage

arrange_isobole(iso_unordered, yps = 1e-09)

Arguments

iso_unordered	unordered data.table(xp,yp)
yps	an offset for zero-values

Details

1. normal from x = 0 to y = 0 2. log scale 3. order from y = 0 to x = 0 4. log scale from y = 0 to x = 0 5. normal, L1 metric 6. normal, canberra metrix (see dist)

Then, take the path with minimal path length, see getPathlength

Value

an ordered isobole
