Determining the break points by hist() leads to errors (PR#2432)
Hi,
if I dermine the break points using the hist() function and then try
to re-use these in a new histogram, R fails. Here is an example of the
problem:
##First, plot a histogram:
data(islands)
foo <- hist(islands,freq=T)
##Now, try plot it again, with the previously determined break points:
hist(islands,breaks=foo$breaks,freq=T)
##... this lead to the warning message:

breaks in hist()
Dear listers,
A quick question about breaks in hist().
The histogram is highly screwed to the right, say, the range of the vector is [0, 2], but 95% of the value is squeezed in the interval (0.01, 0.2). My question is : how to set the breaks then make the histogram look even?
Thanks in advance,

How hist() decides breaks?
Hi Folks,
I'd like to know how hist() decides how many cells to use
when it ignores my "suggestion" to use say 'hist(...,breaks=50)'.
More specifically, I have the results of 10000 simulations,
each returning an 8-vector, therefore 8 variables each with
10000 values. Some of these 8 have somewhat skew distributions.
Say one of these 8 variables is X.
I ask for H <-

unexpected breaks in hist
Hello R-list,
I've been using hist to plot histograms of some data, but I get variable
numbers of bins. I understood from reading the help file that breaks will
set the number of bins. Please correct me if I'm wrong.
I'm plotting measures from subsets of a larger data set. Depending on the
data subset the number of bins varies despite having set breaks to 5 in
all cases.

Understanding R Hist() Results...
Think I'm missing something to understand what is going on with hist(...)
http://n2.nabble.com/What-is-going-on-with-Histogram-Plots-td3022645.html
For my example I count 7 unique years, however, on the histogram there only 6. It looks like the bin to the left of the tic mark on the x-axis represents the number of entries for that year, i.e. Frequency.
I guess it looks like the bin for

superimpose density line over hist
Hi all,
I'm trying to superimpose a rchisq density line over a histogram with
something like:
hist(alnlength)
lines(density(rchisq(length(alnlength), 4)),col="red")
But the rchisq line won't appear anywhere,
Anyone knows what I am missing here?
Thanks in advance,
Albert.

hist.default documentation
I think there are a couple of things in ?hist that are not quite as
clear as they could be.
(1)
freq: logical; if 'TRUE', the histogram graphic is a representation
of frequencies, the 'counts' component of the result; if
'FALSE', _relative_ frequencies ("probabilities"), component
'density', are plotted. Defaults to

How to change the number of bins in "hist" function?
Hi all,
I am doing histogram using the "hist" function. For some reason, the
histogram does not look good... is there a way I can change the number of
bins, and/or change the way that data gets binned... so that I can obtain a
better looking histogram?
Thanks a lot!

I guess the histogram is as you wrote. See

Histograms rotated, side-by-side
Hi there,
I am wanting to create 8 side-by-side histograms which have been rotated 90
degrees clockwise from how they usually sit.. all with the same scales. Is
someone able to help me out?
Thanks so much,

hist() is designed so that the total area sums to 1. You should build you desired behavior using a barchart.

hist clarification
Can someone help me with a misunderstanding I'm having with hist? I
expected, from the example below, that the number of bins would always be 10
and the length of the counts array the same. According to the help section
'breaks' can be a integer indicating the number of bins. From the example
below, the number of bins (length of the counts array) varies. Am I wrong in
expecting the

How to draw a rect() behind a hist() ?
Hi,
I have the following code:
hist(gps$heartpercent, breaks=5)
rect(90, par("usr")[3], 100, par("usr")[4], col = "red")
How do I get the rectangle to appear behind the histogram. Barring that,
how can I make certain bars of the histogram to be a certain color?
Thanks,

Rank samples by breaks in hist and assign result as factor
Hi R users,
My goal is to rank my samples according to how they fall out in a
histogram with 10 bins to produce a ranking for each sample according
to where it falls on the histogram, with a "1" to represent one tail
of the hist, a "10" to represent the other tail, and a "5" for the
median/mean. I have a number of different data sets to do this with
and in all cases

hist will not use parameter xaxs (PR#4219)
Full_Name: Mark Wall
Version: 1.6.0
OS: linux
Submission from: (NULL) (63.251.119.254)
I want to plot a histogram of a *subset* of some data:

>hist(t,right=FALSE,breaks=10,xlim=c(0,5),xaxs="i")
This means I should plot a histogram from 0 to 5 with breaks at 1,2,3,4. This
should produce exactly 5 bars of frequency=1. Instead I get 5 and 1/4 bars. I

labels cut partially on hist
Dear List,
I have the following function where I plot on one page a histogram and a boxplot.
I use option labels = TRUE in hist to show labels. However the label on the highest bar in the
histogram is not showing entirely. How can I correct this?
Thanks for any suggestions?

Thin bars in R hist !!??
Hi,
I am trying to plot a histogram with my dataset that has 68 elements, 67 of
which are zero and the last one is 18. It can be reproduced as follows:
x<-array(0, dim=(68))
x[1] = 18
I am trying to plot its histogram using:
hist(x, breaks=10, xlim=c(0, 100), axes=F)
axis(2, at=seq(0, 70, 5)) # for the y-axis
axis(1, at=seq(0, 100, 10)) # for the x-axis
