extract_feature_length | R Documentation |
Signatures will usually be of different lengths. In a comparison, the length of the shorter signature represents the potential length for a match.
extract_feature_length(aligned)
aligned |
data frame with variable x (for location) and two or more measurements (the bullets entry in the list returned from sig_align) |
integer value of the length of the shorter signature.
