[R] Including percentage values inside columns of a histogram

[Rui Barradas]

Hello,

The function Hist comes from what package?

Are you sure you don't want a bar plot?


agg <- aggregate(Amount ~ Date, datasetregs, sum)
bp <- barplot(Amount ~ Date, agg)
with(agg, text(bp, Amount/2, labels = Amount))


Hope this helps,

Rui Barradas
