The one you need is las.
Without trying to wade thru your mangled HTML data (dput() is the best
way to provide reproducible data), check this out:
barplot(runif(5), names.arg = c("25/08/2004", "26/09/2004",
"02/11/2004", "11/11/2004", "22/11/2004"), main = 'Females 2005', ylab
= ' Age/Days', xlab = 'Birth/Hatch date', las=2)
You'll need to mess with label positioning, and with margin size, to
get everything looking as you wish.
But I'm not sure this is the most effective way to show
irregularly-spaced dates. Why not convert your dates to Date or other
time series, and plot them to scale as points?
