MsData-class: Main class for interacting with MS data

In thomasp85/MSsary: LC-MS/MS analysis in R

Description

This class is the main entry point for interacting with MS data in the MSsary package. It is designed to seamlessly integrate data from raw data files and additional results from various algorithms. Furthermore it provides a mean to commit persistent changes to the raw data (e.g. filtering or recalibration), that will be available across sessions in a non-destructive manner.

Usage

## S4 method for signature 'MsData'
show(object)

## S4 method for signature 'MsData'
length(x)

## S4 method for signature 'MsData'
editHistory(object)

Arguments

object	An MsData object
x	An MsData object

Details

Behind the scene an SQLite-based file is created that handles all deviations and additions to the raw data. The file is named after the raw data file but has a .sary file extension to illustrate its relationship to this package. Because it is just an SQLite database file the data generated with MSsary can easily be accessed from other programs.

Methods (by generic)

• show: Short summary of content

• length: Number of scans in the raw data

• editHistory: Get the edit history of the object

Slots

connections

An MsConnections reference class object

Constructors

Objects of class MsData can be created either from scratch with createMsData or from an already created sary-file loadMsData.
