divideByReference: Divide assay columns by a reference column
In scp: Mass Spectrometry-Based Single-Cell Proteomics Data Analysis

Description Usage Arguments Details Value Examples

The function divides the sample columns by a reference column. The sample and reference columns are defined based on the provided colDataCol variable and on regular expression matching.

1	divideByReference(obj, i, colDataCol, samplePattern = ".", refPattern)

`obj`	A `QFeatures` object
`i`	A `numeric()` or `character()` vector indicating from which assays the `rowData` should be taken.
`colDataCol`	A `character(1)` indicating the variable to take from `colData(obj)` that gives the sample annotation.
`samplePattern`	A `character(1)` pattern that matches the sample encoding in `colDataCol`. By default all samples are devided (using the regex wildcard `.`).
`refPattern`	A `character(1)` pattern that matches the carrier encoding in `colDataCol`. Only one match per assay is allowed, otherwise only the first match is taken

The supplied assay(s) are replaced with the values computed after reference division.

A QFeatures object

data("scp1")
scp1 <- divideByReference(scp1, 
                          i = 1, 
                          colDataCol = "SampleType",
                          samplePattern = "Macrophage",
                          refPattern = "Ref")
