sliceFileSet {sesame} | R Documentation

## Slice a fileSet with samples and probes

### Description

Slice a fileSet with samples and probes

### Usage

    sliceFileSet(fset, samples = fset$samples, probes = fset$probes, memmax = 10^5)

### Arguments

`fset` | a sesame::fileSet, as obtained via readFileSet
`samples` | samples to query (default to all samples)
`probes` | probes to query (default to all probes)
`memmax` | maximum items to read from file to memory, to protect from accidental memory congestion.

### Value

a numeric matrix of length(samples) columns and length(probes) rows

### Examples

    ## create two samples
    fset <- initFileSet('mybetas2', 'HM27', c('s1','s2'))

    ## a hypothetical numeric array (can be beta values, intensities etc)
    hypothetical <- setNames(runif(fset$n), fset$probes)

    ## map the numeric to file
    mapFileSet(fset, 's1', hypothetical)

    ## get data
    sliceFileSet(fset, 's1', 'cg00000292')
