normalize_by_feature_property: Normalization of LC-MS/MS Data

In vladpetyuk/vp.misc: Miscellaneous functions used by Vlad Petyuk for proteomics data analysis

Description

Fits a nonparametric trend into relative abundance data. Any significant (at this point just any) trend is corrected. Converts one ExpressionSet/MSnSet to another ExpressionSet/MSnSet.

Usage

normalize_by_feature_property(
  eset,
  property,
  method = c("lowess", "loess"),
  ...
)

Arguments

eset	ExpressionSet/MSnSet object
property	character the column in the fData that the relative intensities regress against.
method	character either "lowess" or "loess" at this point.
...	passed to lowess or loess.

Note

So far the only property I have in mind is elution time in label-free LC-MS/MS data.
