[R] Help on BarPlot

[Thomas Roth (geb. Kaliwe)]

Hi,

#There are a lot of examples for barplot if you just type

example(barplot)

# i altered one slightly to put the values on top of each bar

mp <- barplot(VADeaths)     # default
#tot <- colMeans(VADeaths)   #changed this line
tot = colSums(VADeaths)    #wether you need max, min, mean , colSums 
will depend on your data
text(mp, tot + 4, format(tot), xpd = TRUE, col = "blue")


#you should be able to get it from here


Thomas
