annotate_lipids {lipidr} | R Documentation

## Parse molecule names to extract lipid class and chain information.

### Description

Parse lipid names to return a data.frame containing lipid class, total chain length and unsaturation. Lipids should follow the pattern 'class xx:x/yy:y', with class referring to the abbreviated lipid class, xx:x as the composition of the first chain and yy:y as the second chain. Alternatively, lipids can be supplied following the pattern 'class zz:z', where zz:z indicates the combined chain length and unsaturation information.

### Usage

    annotate_lipids(molecules, no_match = c("warn", "remove", "ignore"))

### Arguments

`molecules` | A character vector containing lipid molecule names.
`no_match` | How to handle lipids that cannot be parsed? Default is to give warnings.

### Value

A data.frame with lipid annotations as columns. Input lipid names are given in a column named "Molecule".

### Examples

    lipid_list <- c(
      "Lyso PE 18:1(d7)",
      "PE(32:0)",
      "Cer(d18:0/C22:0)",
      "TG(16:0/18:1/18:1)"
    )
    annotate_lipids(lipid_list)
