Binning raw data into blocks for dual inlet analyses
Source:R/blocks_functions.R
orbi_define_blocks_for_dual_inlet.Rd
This function sorts out (bins) data into indivual blocks of reference, sample, changeover time, and startup time.
Usage
orbi_define_blocks_for_dual_inlet(
dataset,
ref_block_time.min,
change_over_time.min,
sample_block_time.min = ref_block_time.min,
startup_time.min = 0,
ref_block_name = setting("di_ref_name"),
sample_block_name = setting("di_sample_name")
)
Arguments
- dataset
A data frame or tibble produced from IsoX data by
orbi_simplify_isox()
- ref_block_time.min
time where the signal is stable when reference is analyzed
- change_over_time.min
time where the signal is unstable after switching from reference to sample or back
- sample_block_time.min
time where the signal is stable when sample is analyzed
- startup_time.min
initial time to stabilize spray
- ref_block_name
the name of the reference being measured
- sample_block_name
the name of the sample being measured
Value
A data frame (tibble) with block annotations in the form of the additional columns described below:
data_group
is an integer that numbers each data group (whether that's startup, a sample block, a segment, etc.) in each file sequentially to uniquely identify groups of data that belong together - this columns is NOT static (i.e. functions likeorbi_adjust_block()
andorbi_segment_blocks()
will lead to renumbering) and should be used purely for grouping purposes in calculations and visualizationblock
is an integer counting the data blocks in each file (0 is the startup block)sample_name
is the name of the material being measured as defined by theref_block_name
andsample_block_name
parameterssegment
is an integer defines segments within individual blocks - this will beNA
until the optionalorbi_segment_blocks()
is calleddata_type
is a text value describing the type of data in eachdata_group
- for a list of the main categories, callorbi_get_settings("data_type")
