noridx {LipidomicsR}

noridx()

Description

An integrated function that call nor.relative() and nor.absolute(), for simplifying.

Usage

noridx(data, radio.data = NULL,
normalization.mode='both',
sample = 1:5, normalize_to = 2:5,
Inlabel=c('PE(17:0/17:0)','PC(17:0/17:0)','PS(14:0/14:0)'),
relative_as_default = TRUE,
relative.mannual = NULL)

Arguments

data

Data frame, row lipidomics data.

radio.data

Data frame. Characteristic of the radio label data. The row name must be the exact channel name of the label. Molecular mass should be provided in a column named "Mass". Concentration should be provided in a column named "Concentration(mg/ml)".

normalization.mode

Character. "absolute" tp output absolute normalization index 'relative' to output relative normalization index. "both" to output both of them. Default as "both".

sample

Vector. Column of sample added with isotope label. Default as 2:5.

normalize_to

Vector. The column of samples that used as the standard for normalization.

Inlabel

Inlabel Vector. Name of Internal label. Default as c('PE(17:0/17:0)','PC(17:0/17:0)','PS(14:0/14:0)')

relative_as_default

Logical, default as TRUE for automatically searching for internal label data.

relative.mannual

Vector, the exact channel name (if you want to define the channel of internal label mannually).

Value

1. normalization.mode='both'. A list of data frames of normalization indexes of the two modes. 2. normalization.mode='absolute' or 'relative'. A data frame of the respective normlaization index.
