ncdf4_update_ri: Update retention time index on a NCDF4 file

In TargetSearch: A package for the analysis of GC-MS metabolite profiling data

Description

Performs retention time index (RI) correction on a CDF file, using the retention markers found by RIcorrect(), or to force the markers time if, for example, the RI markers were not co-injected with the biological samples. It wraps around rt2ri()

Usage

ncdf4_update_ri(cdfFile, observed, standard)

Arguments

cdfFile	Path to the CDF file
observed	The observed RI markers retention times'.
standard	The RI of said markers.

Details

This function is similar to fixRI(), with the difference that is acts upon a single file, whereas fixRI() requires a tsSample object.

Value

Returns invisible

Note

This function is meant to be used internally. It is exposed for convenience.
