plot(x, col="black", 
     xlab="mass", ylab="intensity", 
     type=ifelse(is(object=x, class2="SinglePeakList"), "h", "l"),
     xlim=c(ifelse(length(x@mass)>0, min(x@mass), 0),
            ifelse(length(x@mass)>0, max(x@mass), 1)),
     ylim=c(0, ifelse(length(x@intensity>0), max(x@intensity), 1)),
     main=x@metaData$name, sub=x@metaData$file, 
     cex.sub=0.75, col.sub="#808080",

Examples

## load library
library("MALDIquant");

## create a SingleSpectrum object by default constructor
s <- createSingleSpectrum(mass=1:100, intensity=rnorm(100)^2,
    metaData=list(name="unrealistic example"));

## show some details
s;

## plot spectrum
plot(s);
