rsd_calculator: Calculate Relative Standard Deviation (RSD)

In LipidomicsR: Elegant Tools for Processing and Visualization of Lipidomics Data

Calculate Relative Standard Deviation (RSD)

Description

This function calculates the relative standard deviation (RSD) based on the specified data range.

Usage

rsd_calculator(
  data,
  start,
  end,
  threshold = 0.2,
  show.del = FALSE,
  del.zero = TRUE
)

Arguments

data	The data frame containing abundance data.
start	The starting column index of the QC data range.
end	The ending column index of the QC data range.
threshold	The threshold value for RSD. Default is 0.2.
show.del	Logical value indicating whether to show the deleted data. Default is FALSE.
del.zero	Logical value indicating whether to delete rows with all QC being zero . Default is TRUE.

Value

A data frame containing the calculated RSD values and the corresponding data.

Examples

qc_1=rnorm(n=5,mean=0.3,sd=0.2)
qc_2=rnorm(n=5,mean=0.3,sd=0.2)
qc_3=rnorm(n=5,mean=0.3,sd=0.2)
qc_4=rnorm(n=5,mean=0.3,sd=0.2)
qc_5=rnorm(n=5,mean=0.3,sd=0.2)
WT_1=rnorm(n=5,mean=0.3,sd=0.1)
