x3p file of a 3d topological bullet surface is processed at surface
crosscut y,
measurements outside the bullet grooves in the crosscuts are left out, and
a loess smooth is used (see ?loess for details) to remove the big
structure.
Arguments
- ccdata
crosscut as returned from x3p_crosscut
- grooves
The grooves to use as a two element vector, if desired
- span1
The span for the loess fit to get from the profile to the raw signature
- span2
The span for the loess fit to smooth the raw signature
Examples
data(br411)
cc <- x3p_crosscut_optimize(br411)
ccdata <- x3p_crosscut(br411, cc)
grooves <- cc_locate_grooves(ccdata)
signature <- cc_get_signature(ccdata, grooves)
if (FALSE) {
# Set the data up to be read in, cleaned, etc.
