counts_proportions {weitrix} | R Documentation

## Produce a weitrix of proportions within groups

### Description

Produce a weitrix of proportions between 0 and 1. The input is read counts at a collection of features in a collection of samples. The features need to be grouped, for example by gene. The proportions will add to 1 within each group.

### Usage

    counts_proportions(counts, grouping, verbose = TRUE)

### Arguments

`counts` | A matrix of read counts. Rows are peaks and columns are samples.
`grouping` | A data frame defining the grouping of features. Should have a column "group" naming the group and a column "name" naming the feature (corresponding to `rownames(counts)`).
`verbose` | If TRUE, output some debugging and progress information.

### Value

A SummarizedExperiment object with metadata fields marking it as a weitrix.

### Examples

    grouping <- data.frame(
        group=c("A","A","A","B","B"),
        name=c("p1","p2","p3","p4","p5"))

    counts <- rbind(
        p1=c(1,2,0),
        p2=c(0,1,0),
        p3=c(1,0,0),
        p4=c(0,0,1),
        p5=c(0,2,1))

    wei <- counts_proportions(counts, grouping)

    weitrix_x(wei)
    weitrix_weights(wei)
    rowData(wei)
