rowPairedTP {RnBeads} | R Documentation

## rowPairedTP

### Description

performs a two-sided t-test for paired samples on each row of a matrix X with the indices inds.1 vs indices inds.g2 as group assignments.

### Usage

    rowPairedTP(X, inds.g1, inds.g2 = -inds.g1, alternative = "two.sided")

### Arguments

`X` | Matrix on which the test is performed for every row
`inds.g1` | column indices of group 1 members. `length(inds.g1)==length(inds.g2)` has to hold true.
`inds.g2` | column indices of group 2 members. `length(inds.g1)==length(inds.g2)` has to hold true.
`alternative` | Testing alternative. Must be one of "two.sided" (default),"less","greater" or "all". in case of "all" a data frome with corresping alternative variables is returned. Otherwise the result is a vector.

### Value

vector (or data.frame if alternative=="all") of p-values from a paired t-test

### Note

Requires `matrixStats` package
