to get a histogram with y axis as percentage, I wrote the following code

histogram(data)
now , how to input the percentage and cumulative percentage on top of each
bar?
You will need a custom panel function, along the lines of
mypanel -
function(x, breaks, nint = round(log2(length(x)) + 1), ...)
{
if (missing(breaks))
breaks - do.breaks(range(x, finite = TRUE), nint)
panel.histogram(x, breaks = breaks, ...)
h - hist(x, breaks = breaks, plot = FALSE)
breaks - h$breaks
nb - length(breaks)
yy - 100 * h$counts / length(x)
panel.text(x = (breaks[-1] + breaks[-nb])/2, y = yy,
labels = round(cumsum(yy), 2), pos = 3)
}
histogram(data, panel = mypanel)

Re: [R] how to make a histogram with percentage on top of each bar?
Hi,
Stackoverflow had an example. Forgot the contributor's name but it shows
percentages at the top. I use it as it is as I am not the expert.
png(Histogram.png)
pdata-read.csv(histogram.csv,header=T)
histPercent - function(x, ...) {
H - hist(pdata$y, plot = FALSE)
H$density - with(H, 100 * density* diff(breaks)[1])
labs - paste(round(H$density), %, sep=)
plot(H, freq = FALSE, labels = labs, ylim=c(0, 1.08*max(H$density)),...)
}
histPercent(pdata$y, col=gray, xlab=Measured Values, main=Histogram Bytes
vs Time)
graphics.off()
Thanks,
Mohan

Hi york8866, There is a new function in the plotrix package, barlabels that will probably do what you want. Look for version 3.4-2, which should be available in a few days.
