%description
Provides functions for processing Shimadzu gas chromatography-mass
spectrometry (GC-MS) exported text files, extracting Chemical Abstracts
Service (CAS) numbers and peak areas, building abundance matrices,
annotating compounds, and screening based on occurrence frequency. The
package is designed for organizing, identifying, and screening volatile
compounds in metabolomics and environmental studies.
