correct_iso_base: 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).

Usage

correct_iso_base(df, d13c_correction, methanol_13c, 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().
c13_correction	difference between measured USGS40 value and expected USGS40 value (-26.39 per mil). If IonVantage output has already been corrected, then enter 0.
methanol_13c	13C signature of the methanol used for methylation.

Value

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