If you want to change the fill colours, then you need to specify fill
instead of colour
ggplot(ageincgraph, aes(x = age, y = rate, fill = era)) +
geom_bar(position = "dodge", stat = "identity") +
scale_fill_manual(values=c("red","orange","yellow"))

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to
say what the experiment died of.

The plural of anecdote is not data.

The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of
data.
