Restricts input metabolomics feature table in
metabData object to a
range of retention times defined by
filterRT(data, rtmin, rtmax)
formatted metabolomics data frame.
lower range of retention times for analysis. If "min", defaults to minimum observed retention time. .
upper range of retention times for analysis. If "max", defaults to maximum observed retention time.
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.
rtmax should be
set slightly before and slightly after the first and last commonly observed
A data frame of metabolomics features, limited to time window
