how can I treat data organised in classes and frequencies?

Hello everyone,
I am trying to plot a histogram from the following code:
dat-read.table(file=C:\\Documents and Settings\\Owner\\My
Documents\\Yeast\\Yeast.txt,header=T,row.names=1)
file.show(file=C:\\Documents and Settings\\Owner\\My
Documents\\Yeast\\Yeast.txt)
x-dat[2,23:46]
It is hard to respond without reproducible examples. Do
str(dat[2,23:46]) and see what it reports. My guess is that one of
the columns is not numeric. Find out which one it is, fix it and then
try 'hist' again.

Dear Friends,
I am doing a rather simple histogram on a vector of data, MR. I set
breaks for the intervals:
hist(MR,breaks=c(0, 2.9, 5.9, 8.9, 11.9,14.9, 17.9, 20.9))
My question is, how do I change the labels on the tick marks? I have
looked at ?hist and can't find a clue...
Thanks in
Lawrence,
use hist(..., axes=F)
then put your own axis on with axis(1,...)
Example:
y-rnorm(200)
hist(y,axes=F)
axis(2)
axis(1, at=seq(-3,3,1))

Is it possible to draw lattice histograms (i.e. use the histogram() function
and not the hist() function) with objects of class Date?

I think that you can edit the source code of histogram for this:

body(myhist)[9] -
parse(text = c(capture.output(body(myhist)[9])[-6],
} else labels, adj = c(0.5, -0.5), ...)))
r - hist(islands, plot = F)
myhist(r, labels = T, cex =
Here's an example to make the text 18 point. You can set ps=6 to make small

Typical plots with vertical bars are not histograms. Consider barplot
