BSdataSet-class {methylPipe} | R Documentation

## Class "BSdataSet"

### Description

This class is used in the methylPipe library to store a set of BSdata objects

### Objects from the Class

Objects can be created by calls of the form `new("BSdataSet", ...)` or using the function BSdataSet(org,Objlist,names), see below.

### Slots

`Objlist`:

  Object of class `"list"` : a list with more than one item, where each item is a BSdata object

`names`:

  Object of class `"character"` : vector of the names of the objects, i.e. the sample names

`group`:

  Object of class `"character"` : indicating conditions and replicates; replicated samples within the same condition have to be assigned the same group name; if object has only two groups, "C"(control) and "E" (Experiment) should be specified as groups name

`org`:

  refrence genome of class BSgenome

### Methods

"[["

  `signature(x = "BSdataSet")`: subsets the BSdataSet returning a specific BSdata object

"[[<-"

  `signature(x = "BSdataSet")`: replaces the specific BSdata object in the BSdataSet

"["

  `signature(x = "BSdataSet")`: subsets the BSdataSet returning another BSdataSet
