Extended binary operators for easy subsetting.
x %~% target
Similar(x, target, tol = Inf)Arguments
- x, target
numeric vectors
- tol
tolerance for similarity
Value
A logical vector of the same length of x.
Details
%~% can be thought as a "similar" operator. It's a fuzzy version of
%in% in that returns TRUE for the element of x
which is the (first) closest to any element of target.
Similar is a functional version of %~% that also has a
tol parameter that indicates the maximum allowed tolerance.

# Practical use case: vertical cross-section at
