ldSetOptions {oligoClasses} | R Documentation

## Set/check large dataset options.

### Description

Set/check large dataset options.

### Usage

    ldSetOptions(nsamples=100, nprobesets=20000, path=getwd(), verbose=FALSE)
    ldStatus(verbose=FALSE)
    ldPath(path)

### Arguments

`nsamples` | number of samples to be processed at once.
`nprobesets` | number of probesets to be processed at once.
`path` | path where to store large dataset objects.
`verbose` | verbosity (logical).

### Details

Some functions in oligo/crlmm can process data in batches to minimize memory footprint. When using this feature, the 'ff' package resources are used (and possibly combined with cluster resources set in options() via 'snow' package).

Methods that are executed on a sample-by-sample manner can use ocSamples() to automatically define how many samples are processed at once (on a compute node). Similarly, methods applied to probesets can use ocProbesets(). Users should set these options appropriately.

`ldStatus` checks the support for large datasets.

`ldPath` checks where ff files are stored.
