[R] scaling x-axis in hist function

[Henrique Dallazuanna]

Try this:

hist(all$PI_HAT, labels=T, main="PI_HAT distribution (All)",
xlab="PI_HAT",ylab="count", col="gray",ylim=c(0,15), axes=F)
axis(2)
axis(1, at=seq(0,1, by=0.1), labels=seq(0,1, by=0.1))

runif generate a sample of Uniform Distribution, see ?runif.
