Extract signature from crosscut — cc_get

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.

Usage

cc_get_signature(ccdata, grooves = NULL, span1 = 0.75, span2 = 0.03)

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; if span2 is set to NA, no second smoothing will be done.

Value

data frame

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) { # \dontrun{
# Set the data up to be read in, cleaned, etc.
