pairwise_ratios: Pairwise ratios of vector elements and matrix rows or columns

In mikemc/metacal: Bias estimation and calibration for metagenomics experiments

Description

For a matrix, computes the ratios of the supplied margin (1 = rows, 2 = cols). Otherwise, computes the ratios of the elements.

Usage

pairwise_ratios(x, ..., f = `/`, filter = TRUE, set_names = TRUE, sep = ":")

## Default S3 method:
pairwise_ratios(x, f = `/`, filter = TRUE, set_names = TRUE, sep = ":")

## S3 method for class 'matrix'
pairwise_ratios(x, margin, f = `/`, filter = TRUE, set_names = TRUE, sep = ":")

## S3 method for class 'otu_table'
pairwise_ratios(x, margin = "taxa", f = `/`, filter = TRUE, sep = ":")

## S3 method for class 'phyloseq'
pairwise_ratios(x, margin = "taxa", f = `/`, filter = TRUE, sep = ":")

Arguments

x	A vector or matrix
f	Vectorized binary function applied to numerator and denominator
filter	Whether to filter out redundant pairs
set_names	Whether to set names for the pairs
sep	Seperator for pair names
margin	Margin (1 = rows, 2 = cols) of matrix x to compute ratios of

Examples

  mat <- seq(10) |>
    matrix(nrow = 2)
  rownames(mat) <- paste0('r', seq(2))
  colnames(mat) <- paste0('c', seq(5))
  
  pairwise_ratios(mat, 2)
  pairwise_ratios(mat[1,])
