Keep only columns that are directly relevant for isotopocule ratio analysis. This function is optional and does not affect any downstream function calls.

Usage

orbi_simplify_isox(dataset, add = c())

Arguments

dataset

IsoX data that is to be simplified

add

additional columns to keep

Value

A tibble containing only the 9 columns: filepath, filename, scan.no, time.min, compound, isotopocule, ions.incremental, tic, it.ms, plus any additional columns defined in the add argument

Examples

fpath <- system.file("extdata", "testfile_flow.isox", package="isoorbi")
df <- orbi_read_isox(file = fpath) |> orbi_simplify_isox()
#>  [21ms] orbi_read_isox() loaded 6449 peaks for 1 compound (HSO4-) with 5
#> isotopocules (M0, 33S, 17O, 34S, and 18O) from testfile_flow.isox
#>  [57ms] orbi_read_isox() read .isox data from 1 file
#>  [5ms] orbi_simplify_isox() kept columns filepath, filename, scan.no,
#> time.min, compound, isotopocule, ions.incremental, tic, and it.ms
