mergeXIC {DIAlignR} | R Documentation

## Merge two XICs into one

### Description

Both extracted-ion chromatograms must have same number of rows. Missing values are not allowed. Intensities are weighted-averaged.

### Usage

    mergeXIC(XIC.ref, XIC.eXp, wRef, mergeStrategy)

### Arguments

`XIC.ref` | (data-frame) extracted ion chromatogram from reference run. Must not contain missing values.
`XIC.eXp` | (data-frame) extracted ion chromatogram from experiment run. Must not contain missing values.
`wRef` | (numeric) Weight of the reference XIC. Must be between 0 and 1.
`mergeStrategy` | (string) must be either ref, avg, refStart or refEnd.

### Value

(dataframe) has two columns:

`time` | (numeric)
`intensity` | (numeric)

### time-merging

There are three startegies for calculating time to keep sampling rate equal to parents:
- Use reference time.
- Average time (Non-gap region will have parent's sampling rate).
- Start/end with the average then fixed sampling rate.

    data(XIC_QFNNTDIVLLEDFQK_3_DIAlignR, package="DIAlignR")
    XICs.ref <- XIC_QFNNTDIVLLEDFQK_3_DIAlignR[["hroest_K120809_Strep0%PlasmaBiolRepl2_R04_SW_filt"]][["4618"]]

    ## Not run:
    plot(mergeXIC(XICs.ref[[1]], XICs.eXp[[1]], wRef = 0.5, mergeStrategy = "ref"), type = "l")
