[R] Ploting Histogram with Y axis is percentage of sample for each bin

2011-03-03 Thread leinwand
I'm trying to do something very simple...

I wan to plot a histogram where the y axis represent the percentage of the
total sample that each bin represents. 

I know how to plot a histogram with the counts and density... but can't find
anything that gives me perenct of sample on the y axis. 

Any help is appriciated

Below is the script I'm working with

par(mfrow=c(1,2))
hist(ISIS$ASH_BA1K_ISIS[ISIS$Pest_Status==-1], main=Ash BA 1K Negative
Detection,  xlab=ASH BA 1K)
lines(density(ISIS$ASH_BA1K_ISIS), col=blue)
hist(ISIS$ASH_BA1K_ISIS[ISIS$Pest_Status==1], main=Ash BA 1K Positive
Detection, xlab=Ash BA 1K)
lines(density(ISIS$ASH_BA1K_ISIS), col=red)

Script but no data.

There is a pretty much identical question asked and answered earlier  
today... despite the fact theat the OP doesn't seem to undersatnd or  
be able to apply the directions, you should see if the thread  
Probabilities greather than 1 in HIST answers your question.
