Examples

## Retrieve file paths and sample information for example data
files <- metaboData::filePaths('FIE-HRMS','BdistachyonEcotypes')[1:2]

info <- metaboData::runinfo('FIE-HRMS','BdistachyonEcotypes')[1:2,]

## Perform spectral binning
analysis <- binneR::binneRlyse(files, 
                               info, 
                               parameters = binneR::detectParameters(files))
