score_fun.distMatrix {xcms} | R Documentation |
A similarity scoring function for MS/MS spectra against a reference via a distance matrix.
score_fun.distMatrix(ref, exp, ppmfrag)
ref |
An array of numbers for the refference |
exp |
An array of numbers for the test |
ppmfrag |
A numerical string for the amount of error in |
A simple scoring function to score two arrays of numbers and give a percentage match between the two. Uses a a distance and similarity matrix score system. When the two scores are calculated the percentage score is calculated from the theoritical maximum score and the theoritical minimum score.
