OK, Let's try this again! Here is the reproducible script; it is long because I had to copy the panel dataset here. My question is related to systemfit; I don't know how to get the result for the entire panel.

Sadly you failed to set your email program to send plain text and the data is corrupted at my end.
I also think you need to reduce the size of the data set... the intent here is to increase your understanding, not debug your particular analysis.
I will say that I am having a very challenging time understanding what you are trying to accomplish though. What are the equations that you think need

... and the mailing list is picky about attachments... whatever you attached did not conform to the stringent requirements mentioned in the Posting Guide. Pasting the code right into the email is usually safest, though you DO have to post using plain text (as the Posting Guide indicates) or your code may get mangled by the automatic html format removal.

Unless there is good reason not to, always cc the list -- there are lots of
smarter folks than I on it who can help.
I may or may not have time to look at this. Hopefully someone else will.

Formatted Data File Question for Clustering -Quickie Project
I am trying to learn how to format Ascii data files for scan or read
into R.
Precisely for a quickie project, I found some code (at end of this
email) to do exactly what I need:
To cluster and graph a dendrogram from package (stats).
I am stuck on how to format a text file to run the script.
I looked at the dataset USArrests (which would be replaced by my data
and labels) using UltraEdit. That

reading in a tricky computer program output
Hi R user
I need to read in some values from a computer program output.
I can't change the output format because the developer of the program
doesn't allow to change the format of output.
There are two formats.
First one looks like this

ask for help on nonlinear fitting
I have a table like the following. I want to fit Cm to Vm like this:
Cm ~ Cl+Q1*b1*38.67*exp(-b1*(Vm-Vp1)*0.03867)/(1+exp(-b1*(Vm-Vp1)*0.03867))^2+Q2*b2*38.67*exp(-b2*(Vm-Vp2)*0.03867)/(1+exp(-b2*(Vm-Vp2)*0.03867))^2

tapply output as a dataframe
i use tapply and by often, but i always end up banging my head against
the wall with the output.
is there a simpler way to convert the output of the following tapply to
a dataframe or matrix than what i have here:

dt = data.frame(bucket=rep(1:4,25),val=rnorm(100))
fn = function(x) {

I am currently working with a rather large data set on body temperature

When to use bootstrap confidence intervals?
Hello, I have a question regarding bootstrap confidence intervals.
Suppose we have a data set consisting of single measurements, and that
the measurements are independent but the distribution is unknown. If
we want a confidence interval for the population mean, when should a
bootstrap confidence interval be preferred over the elementary t
interval?
I was hoping the answer would be

slow access to matrix dimnames
hello,
i have been trying to convert my data frames to matrices in the hopes of
speeding up some of my more complicated scripts.
to assist with this, i am trying to create a "matrix column operator"
like $:
"%$%" = function(data,field) {
as.numeric(data[,grep(field,unlist(dimnames(data)[2]))])
}
the idea here is that you can use a matrix like a dataframe:
