filterRT: Filter Features by Retention Time
In metabCombiner: Method for Combining LC-MS Metabolomics Feature Measurements
Description
Usage
Arguments
Details
Value
Description
Restricts input metabolomics feature table in metabData object to a
range of retention times defined by rtmin & rtmax.
Usage
1
Arguments
data
formatted metabolomics data frame.
rtmin
lower range of retention times for analysis. If "min",
defaults to minimum observed retention time.
.
rtmax
upper range of retention times for analysis. If "max", defaults
to maximum observed retention time.
Details
Retention time restriction is often recommended to aid the analysis of
comparable metabolomics datasets. The beginning and end of a chromatogram
typically contain features that do not correspond with true biological
compounds derived from the sample. rtmin and rtmax should be
set slightly before and slightly after the first and last commonly observed
metabolites, respectively.
Value
A data frame of metabolomics features, limited to time window
rtmin ≤ rt ≤ rtmax)
