correct_iso_base2: Process del13C values

In mlfelice/plfaR: Interface for Analyzing IonVantage 13C-PLFA Data

Process del13C values

Description

This function corrects the raw del13C output for methylation and normalizes to the del13C standard USGS40 (L-glutamic acid). This function is an update of the correct_iso_base() function that uses a dataframe matching methanol lot to batch so that we can use different methanol lots for an experiment.

Usage

correct_iso_base2(df, d13c_correction, meth_13c_df, min_height = NULL)

Arguments

df	peak list dataframe or tibble. This should contain the following columns at a minimum: Batch, DataFileName, RetTimeSecs, MajorHeightnA, TotalPeakArea1, DisplayDelta1, Name. This can be the output from import_batch() or import_batch_multi().
d13c_correction	difference between measured USGS40 value and expected USGS40 value (-26.39 per mil). If IonVantage output has already been corrected, then enter 0.
meth_13c_df	Dataframe identifying the 13C signature of the methanol used for each batch. This dataframe should have 2 columns: Batch and Meth13C.

Value

Returns a tibble with columns from input dataframe and a corrected d13C column.
