In octopode/tidychrom: A Dead Simple Toolkit for Quantitative Chromatography

Calculate Cosine Scores Pairwise Takes a grouped tibble of scan data, calculates pairwise cosine similarities

Description

Calculate Cosine Scores Pairwise Takes a grouped tibble of scan data, calculates pairwise cosine similarities

Usage

cosine_pairwise(
  spectra,
  x = "mz",
  thres_cos = 0,
  thres_rt = Inf,
  cores = 1,
  bin
)

Arguments

spectra	Grouped tibble mz/wl and intensity. Should be grouped by scan.
x	Name of x-axis variable (mz or wl, etc.)
thres_cos	Min allowable cosine score for scans to cluster
thres_rt	Max allowable RT difference for scans to cluster

Value

Input tibble but with neighbor and cos columns added

Examples

spectra_clustered <- spectra %>%
  group_by(scan, file) %>%
  cluster_spectra()
