A small piece (b2) is matched to a much larger piece (b1). The lag gives the index location of the best match of b2 in b1.
This function is essentially just a wrapper for my_ccf, but adds a plot of the result for convenience.
get_lag(b1, b2, negperc = 10)
| b1 | vector of striation marks (assuming equidistance between values) |
|---|---|
| b2 | (smaller) vector of striation marks |
| negperc | amount of lead that b2 can have compared to b1 |
list of lag and correlation achieved. The plot shows b2 on b1
