Manually adjust block delimiters — orbi_adjust

This function can be used to manually adjust where certain block starts or ends using either time or scan number. Note that adjusting blocks removes all block segmentation. Make sure to call orbi_segment_blocks() after adjusting block delimiters.

Usage

orbi_adjust_block(
  dataset,
  block,
  filename = NULL,
  shift_start_time.min = NULL,
  shift_end_time.min = NULL,
  shift_start_scan.no = NULL,
  shift_end_scan.no = NULL,
  set_start_time.min = NULL,
  set_end_time.min = NULL,
  set_start_scan.no = NULL,
  set_end_scan.no = NULL
)

Arguments

dataset: tibble produced by orbi_define_blocks_for_dual_inlet()
block: the block for which to adjust the start and/or end
filename: needs to be specified only if the dataset has more than one filename
shift_start_time.min: if provided, the start time of the block will be shifted by this many minutes (use negative numbers to shift back)
shift_end_time.min: if provided, the end time of the block will be shifted by this many minutes (use negative numbers to shift back)
shift_start_scan.no: if provided, the start of the block will be shifted by this many scans (use negative numbers to shift back)
shift_end_scan.no: if provided, the end of the block will be shifted by this many scans (use negative numbers to shift back)
set_start_time.min: if provided, sets the start time of the block as close as possible to this time
set_end_time.min: if provided, sets the end time of the block as close as possible to this time
set_start_scan.no: if provided, sets the start of the block to this scan number (scan must exist in the dataset)
set_end_scan.no: if provided, sets the end of the block to this scan number (scan must exist in the dataset)

Value

A data frame (tibble) with block limits altered according to the provided start/end change parameters. Any data that is no longer part of the original block will be marked with the value of orbi_get_settings("data_type_unused"). Any previously applied segmentation will be discarded (segment column set to NA) to avoid unintended side effects.
