plotMsSpectrum(x, i)

Arguments

i	series number of peaks which you want to plot

Examples

##---- Should be DIRECTLY executable !! ----
##-- ==>  Define data, use random,
##--	or do  help(data=index)  for the standard data sets.

## The function is currently defined as
function (x, i) 
{
    no <- x[[i]]$a[[2]]
    no <- gsub("# of Peaks", "Number of Peaks = ", no)
    y <- data.frame(x[[i]]$b)
    colnames(y) <- c("mass", "absolute", "relative")
    plot(as.character(y$mass), as.character(y$relative), type = "h", 
        xlab = "Mass/Charge", ylab = "Relative Intensity", col = ifelse(y$relative == 
            "100.00", "red", "black"), main = no)
  }
