lib_demo: Demo formula library (200 - 300 Da, neutral mass)
In ume: Ultrahigh-Resolution Mass Spectrometry Data Evaluation for Complex Organic Matter
lib_demo R Documentation
Demo formula library (200 - 300 Da, neutral mass)
Description
Contains a small molecular formula library for demonstration and
validation purposes. Complete formula libraries are available
in the 'ume.formulas' data package.
Usage
lib_demo
Format
A data.table having ~115,111 rows and 12 variables:
- vkey
First two digits represent the formula library version;
last digits are unique identifiers for each formula
- mf
Neutral molecular formula (no differentiation of isotopes)
- mass
Calculated exact neutral mass of a formula (based on ume::masses)
See Also
Other ume data:
known_mf,
masses,
mf_data_demo,
nice_labels_dt,
peaklist_demo,
tab_ume_labels
Examples
data(peaklist_demo)
