orbi_filter_isox: Basic generic filter for IsoX data

In isoorbi: Process Orbitrap Isotopocule Data

Basic generic filter for IsoX data

Description

A basic filter function orbi_filter_isox() for file names, isotopocules, compounds and time ranges. Default value for all parameters is NULL, i.e. no filter is applied.

Usage

orbi_filter_isox(
  dataset,
  filenames = NULL,
  compounds = NULL,
  isotopocules = NULL,
  time_min = NULL,
  time_max = NULL
)

Arguments

dataset	The IsoX data to be filtered
filenames	Vector of file names to keep, keeps all if set to NULL (the default)
compounds	Vector of compounds to keep, keeps all if set to NULL (the default)
isotopocules	Vector of isotopocules to keep, keeps all if set to NULL (the default)
time_min	Minimum retention time in minutes (time.min), no minimum if set to NULL (the default)
time_max	Maximum retention time in minutes (time.min), no maximum if set to NULL (the default)

Value

Filtered tibble

Examples

fpath <- system.file("extdata", "testfile_flow.isox", package = "isoorbi")
df <-
  orbi_read_isox(file = fpath) |>
  orbi_simplify_isox() |>
  orbi_filter_isox(
    filenames = c("s3744"),
    compounds = "HSO4-",
    isotopocules = c("M0", "34S", "18O")
  )
