seedRegions {microRNA} | R Documentation

## A function to retrieve the seed regions from microRNA sequences

### Description

The seed region of a microRNA consists of a set of nucleotides at the 5' end of the microRNA, typically bases 2 through 7, although some times 8 is used.

### Usage

    seedRegions(x, start = 2, stop = 7)

### Arguments

`x` | A vector of microRNA sequences.
`start` | The start locations, can be a vector.
`stop` | The stop locations, can be a vector.

### Details

We use `substr` to extract these sequences.

### Value

A vector of the same length as `x` with the substrings.

     seedRegions(hsSeqs[1:5])
     seedRegions(hsSeqs[1:3], start=c(2,1,2), stop=c(8,7,9))
