## batch function for task batch execution

### Description

batch function for task batch execution

### Usage

    batch(input = NULL, criteria = NULL, type = c("ITEM", "CRITERIA"))

### Arguments

`input` | character, ID of the input on which you wish to batch on. You would usually batch on the input containing a list of files. If left out, default batching criteria defined in the app is used.
`criteria` | a character vector, for example. `c("metadata.sample_id", "metadata.library_id")`. The meaning of the above batch_by dictionary is - group inputs (usually files) first on sample ID and then on library ID. If NULL, using type "ITEM" by default.
`type` | Criteria on which to batch on - can be in two formats."ITEM" and "CRITERIA". If you wish to batch per item in the input (usually a file) using "ITEM". If you wish a more complex criteria, specify the "CRITERIA" on which you wish to group inputs on. Please check examples.

### Value

a list of 'batch_input' and 'batch_by' used for task batch

### Examples

    batch(input = "fastq") # by ITEM
    batch(input = "fastq", c("metadata.sample_id", "metadata.library_id"))
    # shorthand for this
    batch(input = "fastq", c("metadata.sample_id", "metadata.library_id"), type = "CRITERIA")
