DerivData-class {CNAnorm} | R Documentation

## Class "DerivData"

### Description

A Class containing data derived from InData used for further computation and plotting.

### Objects from the Class

Objects can be created by calls of the form `new("DerivData")`, however DerivData is typically populated using methods. If a slot has not been populated yet, it has zero length, otherwise slots have the same length as `InData`.

### Slots

`ratio`:

  Numeric vector with ratio Test/Normal. Optionally GC corrected.

`ratio.s`:

  Numeric vector with smoothed ratio.

`ratio.n`:

  Numeric vector with normalized ratio.

`ratio.s.n`:

  Numeric vector with normalized and smoothed ratio.

`segID`:

  Numeric vecotr with ID of segmented data (as provided by DNACopy). Each `segment` has a different ID.

`segMean`:

  Numeric vector with mean value of the segment (as provided by DNACopy.)

`segMean.n`:

  Numeric vector with normalized segMean.

`ok4density`:

  Logical vector. Specify wich values have been used to calculate density.

### Methods

length

  `signature(x = "DerivData")`: Returns number of windows.
