Dear All,
I am a undergraduate using R for the first time. It seems like an excellent
program and one that I look forward to using a lot over the next few years,
but I have hit a very basic problem that I can't solve.
I want to produce a standardised histogram, i.e. one where the area under
the
Hi,
how did you evaluate the total area?
Here is a simple example
###
set.seed(100)
x - rnorm(100)
x.h - hist(x, freq=F, plot=F)
x.h
$breaks
[1] -2.5 -2.0 -1.5 -1.0 -0.5 0.0 0.5 1.0 1.5 2.0
2.5 3.0
$counts
[1] 3 4 9 14 22 20 13 7 5 2 1
$intensities
[1] 0.0599 0.0800
Dear Marco,
I compared the maximum values with what I was expecting based on a
calculation in Excel however I've just run the set of commands to calculate
the area:
out - hist(StockReturns, probability=TRUE, plot=FALSE)
out
sum(diff(out$breaks) * out$intensities)
And it seems to have worked
