Can this be used to find fuzzy matching rows?

[rwarnung]

I just postd this question which contains the following example:

x = matrix( 1:100, nrow = 100, ncol= 4 ,byrow = FALSE)
y = x + matrix( .001 * rnorm(n = 400), nrow = 100, ncol= 4)
z = rbind(x,y)
z = z[sample(nrow(z)),]

can fuzzyjoin be used to reduce z to x (at least as a estimate)?

I don't think this is in fuzzyjoin's scope. Despite its name, joins made with fuzzyjoin are deterministic and are not estimates.
