Subject: cumulative frequency distribution plot
To plot a cumulative distribution of, say a behaviorial reaction time
vector, I wrote the following function:
cumhist = function(x)
{
Z = hist( x , plot=F )
plot(1:length(Z$counts),cumsum(Z$counts)/length(x)*100,type="b",axes=F,
ylab="%",xlab="")
axis(1,at=1:length(Z$counts),labels=round(1/Z$mids,digits=0))
axis(2)
}
x must be a vector of the data.
