Select specific samples from correspondance file

Hi!
I wonder how to select specific samples after correspondance? For example remove all quality control samples?

# Example code from https://bioconductor.org/packages/devel/bioc/vignettes/xcms/inst/doc/xcms.html
## Perform the correspondence
pdp <- PeakDensityParam(sampleGroups = sampleData(xdata)$sample_group,
                        minFraction = 0.4, bw = 30)
xdata <- groupChromPeaks(xdata, param = pdp)

With filterFeatureDefinitions  its possible to filter features, but how to do it for samples?

Many thanks!
Best,
Elise
