aggregateFeaturesOverAssays: Aggregate features over multiple assays

In UCLouvain-CBIO/scp: Mass Spectrometry-Based Single-Cell Proteomics Data Analysis

Aggregate features over multiple assays

Description

This function is a wrapper function around QFeatures::aggregateFeatures. It allows the user to provide multiple assays for which aggregateFeatures will be applied sequentially.

Usage

aggregateFeaturesOverAssays(object, i, fcol, name, fun, ...)

Arguments

object	A QFeatures object
i	A numeric(1) or character(1) indicating which assay to transfer the colData to.
fcol	The feature variables for each assays i defining how to summarise the QFeatures. If fcol has length 1, the variable name is assumed to be the same for all assays
name	A character() naming the new assay. name must have the same length as i. Note that the function will fail if of the names in name is already present.
fun	A function used for quantitative feature aggregation.
...	Additional parameters passed the fun.

Value

A QFeatures object

Examples

data("scp1")
scp1 <- aggregateFeaturesOverAssays(scp1, 
                                    i = 1:3,
                                    fcol = "peptide",
                                    name = paste0("peptides", 1:3),
                                    fun = colMeans,
                                    na.rm = TRUE)
