getChildFeatureR 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.

newXICs <- masterXICs_DIAlignR
params <- paramsDIAlignR()
dataPath <- system.file("extdata", package = "DIAlignR")
fileInfo <- DIAlignR::getRunNames(dataPath = dataPath)
features <- getFeatures(fileInfo, maxFdrQuery = 1.00, runType = "DIA_Proteomics")
df.ref <- features$run1[features$run1$transition_group_id == 4618L, ]
df.eXp <- features$run2[features$run2$transition_group_id == 4618L, ]
## Not run: 
getChildFeature(newXICs[[1]], newXICs[[2]], df.ref, df.eXp, params)

## End(Not run)
