getChildFeature {DIAlignR} | R Documentation

## Transform features to child time-domain

### Description

This function transforms the peaks' times to child run's time-domain. The feature intensity is calculated with appropriate method stated in params. Internal missing values are not allowed in timeParent.

### Usage

    getChildFeature(XICs, alignedVec, df.ref, df.eXp, i.ref, i.eXp, params)

### Arguments

`XICs` | (list of data-frames) extracted ion chromatograms from the child run.
`alignedVec` | (data-frame) aligned parent time-vectors. Must have five columns
`df.ref` | (data-frame) contains reference-run features to be transformed. It has a format of `getFeatures` output.
`df.eXp` | (data-frame) contains experiment-run features to be transformed. It has a format of `getFeatures` output.
`params` | (list) parameters are entered as list. Output of the `paramsDIAlignR` function.

### Value

(data-frame) this has a format of `getFeatures` output.
