If you force the slope, it is no longer a regression, so no. It is best to add
those other dependent variables to the regression and evaluate whether their
presence causes the fit to improve and yield signs of coefficients that match
what you expect.

There are exactly 3.154 x e08 seconds in a (non-leap) year. So the error in

Can I use sink() to transfer the MLE results which are a S4 type object to a
text file?
Can someone show me how to do this?

It is the same thing (simply multiply the polynomial by the LCM and you have a
polynomial with integer coefficients).

and proof of irrationality is not hard (Wikipedia has several),
although certainly nontrivial. Proof that it's transcendental is,
requiring e.g. abstract algebra (Lindemann-Weierstrass theorem).

Try this:
mat1 <- matrix(c(1,2,1,2), 2, 2)
mat2 <- matrix(c(0,0,1,2), 2, 2)
> mat1
[,1] [,2]
[1,]11
[2,]22
> mat2
[,1] [,2]
[1,]01
[2,]02
> mat1 == mat2
[,1] [,2]
[1,] FALSE TRUE
[2,] FALSE TRUE
# Get the indices of the elements that are not eq
Thanks alot.
Unfortunately I can not apply this to much bigger matrices as I can not
visually check all the components.

Hi,
I'm using reshape to cast molten data. When I use the following command, R
either crashes (when I use Notepad++) or gives an error (when I use Rgui or
source()), BUT the error occurs not always, maybe only on half the attempts:
w <- cast(v, id + code + productname + year + begin + end + spec
1- I used R packages (design, lasso) to develop and validate prognostic
models. I could have enclosed optimism from the model with and without the
strong irrelevant predictor, but that will make the message very long (against
guidelines for the site).
2- This issue is challenging and
So you need to read a file into R in that format?
Try changing the values in ?read.table. Using the example, I was able
to get the data using:
read.table("clipboard", sep = "=", header = F, colClasses =
c("character", "numeric"))

`pi' is more than irrational - it is transcendental, which mean it cannot be
the zero of a polynomial with integer coefficient. All transcendentals are
irrationals, but not vice-versa.
I have also heard (courtesy: John Nash) that `pi' is the ratio of actual time
it takes to complete your thesi
