need help converting data.frame to time series
Hi
I am a new R user and need some help converting a data frame object to time series.
1. My input is a CSV file, contents something like these:
DATE ,STOCK ,RETURN-A ,RETURN-B, etc.
2009/02/02 ,A ,0.01 ,0.011
2009/01/30 ,A ,0.01 ,0.011

Systemfit
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

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
if I have 10 variables,

Matlab inv() and R solve() differences
I submit the following matrix to both MATLAB and R
x= 0.133 0.254 -0.214 0.116
0.254 0.623 -0.674 0.139
-0.214 -0.674 0.910 0.011
0.116 0.139 0.011 0.180
MATLAB's inv(x) provides the following

-58.15 6.93 -7.89 36.94

... 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.

NADA Data Frame Format: Wide or Long?
I have water chemistry data with censored values (i.e., those less than
reporting levels) in a data frame with a narrow (i.e., database table)
format. The structure is:

$ sampdate: Date, format: "2007-12-12" "2007-12-12" ...

Need Help with Dendrogram and DataFrame Leaf names
I having problem with dendrogram leaf names when I read a tab delimited
file into dataframe;
I have a text file, tab delimited, using read.table into a data frame as
follows:
> test1<-read.table("c:\\R\\data\\Tremont4.txt", header=TRUE, sep="\t")
When I do this the "test1" data frame is picking up my first column

Understanding cenros Error
Before reading water chemistry into a data frame I removed all missing
data. Yet when I try to run cenros() to summarize a specific chemical I get
an error that I do not understand:
with( subset(chem, param=='Ag'), cenros(quant,ceneq1) )
Error in lm.fit(x, y, offset = offset, singular.ok = singular.ok, ...) :
NA/NaN/Inf in 'y'
I would like to learn what I did incorrectly

tip: large plots
Hi all,
I'm working with a bunch of large graphs, and stumbled across
something useful. Probably many of you know this, but I didn't and so
others might benefit.
Using pch="." speeds up plotting considerably over using symbols.
> x <- runif(1000000)
> y <- runif(1000000)
> system.time(plot(x, y, pch="."))

ccf time units
Hi,
I am using ccf but I could not figure out how to calculate the actual lag in
number of periods from the returned results. The documentation for ccf
says:"The lag is returned and plotted in units of time". What does "units of
time" mean? For example:
> x=ldeaths
> x1=lag(ldeaths,1)
> results=ccf(x,x1)
> results

Aggregate by minimum
For each date, I would like to keep the line with the lowest speed and discard the rest. The result would have one line for each date. Can I use aggregate for this?
My table is as follows:
