Show only few chromatograms
Hi all,
I thought I did this before, but just can't figure it out anymore. I have a read about 300 data files into xcms, but I only want to show the base peak chromatogram of few of them.
bpis <- chromatogram(object = raw_data, aggregationFun = "max")
This will get all chromatograms and I thought I could plot only 3 of them like this:
plot(bpis[c(1, 25, 50, 100)])
But this didn't work. Is there way to only show a few chromatograms while raw_data contains the data of about 300 files.
Cheers, Rico
