Re: [R] questions about histogram
it's a frequency histogram. The total area of the bars is 1, and the area of each bar represents its frequency, i.e. 25/50,10/50,10/50,5/50, respectively. And the width of the bars are different.

Try this:

+ 2-10 10
+ 10-100 10
+ 100-1000 5"))

2 2-10 10
3 10-100 10
4 100-1000 5

> x <- read.table(textConnection("0-2 25

+ 10-100 10
+ 100-1000 5"))

[R] questions about histogram
Hi all, I'm a new R user. I have the following information about a data set and how to make a histogram? data number of observations 0-2 25 2-10 10 10-100 10 100-1000 5 I tried barplot(height=...,width=...,...), the output looks right but the x-axis is missing. How to fix it? Also can I use to draw it? Thanks!
