bpaggregate {BiocParallel}

R Documentation

Apply a function on subsets of data frames

Description

This is a parallel version of aggregate.

Usage


## S4 method for signature 'formula,BiocParallelParam'
bpaggregate(x, data, FUN, ..., BPPARAM=bpparam())

## S4 method for signature 'data.frame,BiocParallelParam'
bpaggregate(x, by, FUN, ..., simplify=TRUE, BPPARAM=bpparam())

## S4 method for signature 'ANY,missing'
bpaggregate(x, ..., BPPARAM=bpparam())

Arguments

`x`	A data frame or a formula.
`by`	A list of factors. Data frame `x` will be split accoring to the factors.
`data`	A data frame.
`FUN`	Function to apply.
`...`	Additional arguments for `FUN`.
`simplify`	If set to `TRUE`, the return values of `FUN` will be simplified using `simplify2array`.
`BPPARAM`	An optional `BiocParallelParam` instance determining the parallel back-end to be used during evaluation.

Value

See aggregate.
