Feature Extraction: Proportion of NA values in the middle of the scan.

One of the main problems with 3d scans is NA values in the middle of the 3d scan. Here we are quantifying this by chopping off a portion of the right and left sides of a 3d scan and are then finding the proportion of missing values in the middle of the 3d scan.

assess_middle_na_proportion(x3p, chopoff = 1/8)

Arguments

x3p

scan in x3p format

chopoff

numeric value between 0 and .5 - The percentage of values to chop off of both sides of the scan

Value

proportion of NA values in the middle of 3d scan
