nmr_identify_regions_urine {AlpsNMR} | R Documentation

## NMR peak identification (urine samples)

### Description

Identify given regions and return a data frame with plausible assignations in human urine samples. The data frame contains the column "Bouatra_2013" showing if the proposed metabolite was reported in this publication as regular urinary metabolite.

### Usage

    nmr_identify_regions_urine(
      ppm_to_assign,
      num_proposed_compounds = 5,
      verbose = FALSE
    )

### Arguments

`ppm_to_assign` | A vector with the ppm regions to assign
`num_proposed_compounds` | set the number of proposed metabolites sorted by the number times reported in the HMDB: `HMDB_urine`.
`verbose` | Logical value. Set it to TRUE to print additional information

### Value

a data frame with plausible assignations.
