Precursor ion spectrum of peptide YEVQGEVFTKPQLWP acquired on a MALDI-TOF/TOF. The peptide is labeled with approximately 99% nitrogen-15.

Examples

## plot the spectrum
library(lattice)
maldiExample <- transform(maldiSpectrumYEVQGEVFTKPQLWP, 
  intensity.percent = intensity / max(intensity) * 100)
xyplot(intensity.percent ~ mz,
       data = maldiExample,
       type = "l",
       main = "experimental spectrum",
       xlab = "m/z",
       ylab = "intensity (%)")
