You should go back and read the help for barplot.  Do you really want to plot the whole dataset (say as a stacked barplot)? Then something like this should do it.

barplot(as.matrix(dataset[,2:5]),  col = c("lightblue", "mistyrose", "lightcyan",
                "lavender", "cornsilk"), 
  legend = dataset$Ages, ylim = c(0, 100))

Your values don't add to 100, so I'm not sure what you actually want.  If this isn't what you want then give us more information.


Hope this is helpful,
