Dear Researches,

sorry for disturb. I wish to improve my figure in R plotting the relative
frequencies of my data set.

library(lattice)
a <- c(0,0,0,1,1,2,4,5,6,7,7,7,7,7,8,8,8,8,9,9,9,9,10,10,11)
histogram(a, xlab="myData")

what i wish to do is:

1) invert the order of X and Y (eg: Precent of Total on X-axis and "MyData"
on X-axis)
2) plot not the bar of histogram but a line (i tried with
"lines(density(a))" but the result is not what i wish)

Great Thanks for any helps
Gianni
