Subset peak table

Subsets a peak_table while preserving and subsetting all associated slots (tab, pk_meta, sample_meta, instrument_meta, ref_spectra).

Usage

# S3 method for class 'peak_table'
x[i, j, ..., drop = FALSE]

Arguments

x

A peak_table object.

i

Row indices (samples) to subset.

j

Column indices (peaks) to subset.

...

Additional arguments (ignored).

drop

Passed to the [ indexing operator.

Value

A peak_table object.

Note

Subsetting a peak_table does not modify the associated chrom_list. Methods that rely on the chrom_list (e.g., plot_spectrum) may not work as expected on a subsetted peak_table unless the chrom_list is subsetted separately.
