sliceFileSet {sesame} | R Documentation |
Slice a fileSet with samples and probes
sliceFileSet(fset, samples = fset$samples, probes = fset$probes, memmax = 10^5)
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. |
a numeric matrix of length(samples) columns and length(probes) rows
## 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')
