lattice histogram problem with integers values and nint
been puzzling over this for a day.
Summary
integer variable to use with histogram, 170,000 rows. Value is day of
year. Hist works, lattice histogram with nint does not work (spurious
spikes in display), lattice histogram using breaks=c(0:365) works
fine. Spike values appear to be sum of two adjacent bins. Want to
know if this is a familiar problem, and what the recommended
work-around is.

Modified Histogram functions
Dear all,
I have done further modifications on the histogram functions that I
reported earlier this year, and I hope this can be of use and perhaps
included in the distribution. I have been using this stuff a couple of
months myself, and while it is nothing sophisticated, it has it's
applications. :-) I did a few small modifications today to make it a bit
more compact.
I have modified the

converting histogram to barchart
Hi list,
After a lot of tweaking i have managed to create a histogram with an
overlaying density plot. The histogram shows a sample of birth weights
of babies and the density plot shows birth weights from a much larger
reference populaton. My data is divided in 0.1 Kg bins so in the code
below binweigh=0.1.
The trouble with the current graph is that it is not very clear since

Plotting multiple histograms on same panel
Hey everyone,
So i cant figure this out. when using histogram() from lattice instead
of hist() i get what i want as far as output. But using histogram i can
seem to be able to figure out how to get multiple plots on the same panel.
So
par(mfrow=c(3,2))
for (i in 1:20) hist(rnorm(100),main="",cex.axis=.8)
gets me about what i want but i want to use histogram() cause it gives

Hi Listers,
I am producing some graphics that the commands are in a FUNCTION...
The problem is that I end up viewing just last graphic and in my FUNCTION

How do I view/get the other 3 graphics? Any help?

variable name to hist within apply?
Hello,
After spending sometime trying to generate histograms of all the
numeric variables in a data frame using a for loop, I realized I could
use apply to create the histograms. This was one of those few moments
when I `see' the alternative to looping.
So, I can generate all the histograms with this command:
apply(toblo.df[,-c(40,52)],2,hist) # 40 and 52 are ID's
When I do this, the

superimposing histograms con't
Earlier, I posted the following question:
I want to superimpose histograms from three populations onto the same graph,
changing the shading of the bars for each population. After consulting the
help files and the archives I cannot find out how to do this (seemly)
simple graph. To be clear, I want
- a single x axis (from -3 to 18)
- three groups of bars forming the histograms of each population

I guess the histogram is as you wrote. See

rotated histogram
I would like to make a scatterplot, with a histogram of the x and y
variables above and to the right . I can use layout to set up the areas,
and hist(x,y) works fine for the upper histogram. However, I need a
rotated histogram on the right, and I don't know how to do this. I've
seen a solution with a bar plot on the right, but I'd like to use a
histogram. Do you know how I can do

Dear Help Desk,
Is there any way to change some of the labels on R diagrams?
Specifically in histograms, I would like to:
1. change the word frequency to count.
2. Make the font of the title (Histogram of …) smaller.
3. Have a different word below the histogram than the one occurring in the title (right now if you choose X for your

Histogram with two colors depending on condition
Dear List,
Say, we generate data like this-
dat<-rnorm(1000,1,2)
hist(dat)
How do i make the histogram, say, red (col = 2) before X = dat = 0, and rest say, green (col = 3) beyond X = dat = 0 in R?
The resulting histogram could be like this http://ehsan.karim.googlepages.com/histogram.JPG (edited)

histogram - density on y axis and restriction to interval [0, 1]
Hello,
To indicate probability densities instead of counts on a histogram, I
specify freq = FALSE.
However, I expect that summing all top y coordinates over all the
intervals of the histogram will provide 1.

Histogram with colors
Is there a simple way to plot a histogram with colors?
For example, suppose I generate random points in the
N(2,1) distribution:
x <- rnorm(100000, mean = 2, sd = 1)
Now I would like to plot the histogram:
hist(x)
but I would like to show the bars with x < 0 in red, and the
bars with x >= 0 in lightgreen. Is there any simple way to
do it?
I think I can do it in two steps:

I'm trying to superimpose a line plot onto a histogram but I'm not having
any luck. I've attached the dataset. What I did was:

them onto the histogram:

barplot as histogram
Hello:
I'm dealing with an issue currently that I'm not sure the best way to
approach. I've got a very large (10G+) dataset that I'm trying to create
a histogram for. I don't seem to be able to use hist directly as I can
not create an R vector of size greater than 2.2G. I considered
condensing the data previous to loading it into R and just plotting
the frequencies as a
