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

Subtract peak area from control and standard lipids

Description

All samples are typically run with a 19:0 extraction control and 13:0 standard. This function subtracts peak area contributed by these additions prior to converting peak area to concentration.

Usage

subtract_blanks(df, blanks)

Arguments

df	Dataframe or tibble with named PLFA peak data following format specified by import_batch().
blanks	Vector of the names of samples run as blanks. This should include all samples you want to use for peak subtraction (eg. 13:0 and 19:0) in most cases.

Value

Tibble similar to input with the addition of AreaMinusBlanks column showing peak areas minus area contributed by standard/control lipids.
