I think there is a misunderstanding here.
Some data is censored, but I want to fit the data with a distribution
in the interval [0,24] only. Also, please note that I have other
datasets having values larger than 1000.
Cheers,

Dear David,
You do not need a loop. The vectors are equaly sized, so sum them and then
plot the vector with the sums:
total - A+B+C+D+E+F+G
plot (total, type=l)

you can use tools such as Path Manager 1.1.1 (GPL) on Windows:

Hi Martyn,
I would not expect you to need directories besides Rversion\bin\x64.
That is all I normally have in my path...perhaps because I do a
complete install?
I do not really know how or why it works, so I do not have any great
insight---just my experience. Perhaps someone else will chime in

Hi,
Thanks for the help.
I have now sorted out the issue.

Removing the extraneous text solved the problem - so the only mystery now is

It's working perfectly. I will have a look for an online guide.

Hello,
I would like to get help on the instalation of R.
I have too few free space in my pc hard disk. So I wonder if it is possible
to install R on an external removable hard drive.
Can it be done? How should I proceed?
Thank you for your help.

I can get an array of strings for the data that I want using 'paste()' as
follows:
paste('ma', 1:am$arma[2], '=', coef(am)[1:am$arma[2] + am$arma[1]], sep='')
This results in a vector of strings like:
[1] ma1=1.17760133668255 ma2=0.649795570407939 ma3=0.329456750858276

Is there a library that provides power calculation and sample size
estimation for nonlinear regression?
The task is easy for linear regression with the pwr package, but I
can't find a method for nonlinear regression (estimated with the nls
package).

Path manager has a nice feature. Thanks. While I can see that rcmd is in
the path setting, it is still not recognized as an internal command. That

If you don't want to go with the simple method mentioned by David and Ted, or
you just want some more theory, you can check out:

How to add units (e.g. cm) to the color key of a lattice levelplot?

May I suggest you consult your local statistician. For reasons that (s)he
can answer, your request makes little sense.
Hint: Nonlinear regression is much different than linear regression: The
design matrix -- and hence the variance of estimators -- is a function of
the parameters being estimated.
Groupwise data summarization is a very common task, and it is worth
learning the various ways to do it in R. Josh showed you one way to
use aggregate() from the base package and Michael showed you one way
of using the plyr package to do the same; another way would be
ddply(df, .(Patient, Region),
There is a difference between parsed functions and .R files. What you see when
you type the name of a function alone on the R command line is a text
representation of the parsed function that is ready to run in RAM. That has
none of the comments or whitespace from the function as you wrote it.
I have had similar problems.
I have several installations of R and now I have no control over which one
opens when I try opening a RData file. The RGUI is registered more than
once, but they all have the exact same appearance in the choose programs
menu.
It's become particularly annoying now
