feasible, and how I could achieve well

I want to fit a function to time series. If I had:
x - 1:4
y - 1:4
lm(y~x)
This would fit a simple line to the four points. But if it is represented as a
time series
x - 1:4
t - ts(x)
lm()
So I have a time series in the object t. How do I write a formula for lm? What
do I put in the
Hello!
Please, anybody help me.
Can I calculate area of density was created by:
D - density(x)
In other words I want to know area under curve 'plot(D)'
and It's good to calculate area before and after 0 separately.

That was the one I'd remembered but couldn't find.
Mark Leeds also told me about DistributionFits(fBasics), which I hadn't
seen. There seems to be only a little overlap between the two.
Could I trouble you to expand on AIC (esp. what the function name and

So you want time as the independent variable? Let's say that the
units of y in your first example were seconds- couldn't you just use a
regular lm and say that the units were seconds, minutes, or what ever?
I am probably out of my league here, but I am just not understanding
what it is that you

That should be 1.

That's harder,
Frequently I need to convert a .xls to a .csv (for import into R) and I
do this by opening the file in excel and saving it as a csv. I would
rather do this using WinXP's context menu (right click the xls, choose
convert to csv) but I don't know of a utility that does this. Any
ideas? Thanks,

Dear Mark,
I think you don't need to convert your xls files into csv files to read them
using R. There are several ways to read them such as
the RODBC package and ?read.xls in gdata. Now, if you really want to do the
conversion, try ?xls2csv in gdata as well.

Is there a way to associate descriptions with the objects in the
workspace, and later retrieve them to know what the object was created
for?
