I have Windows 7 64 bit and 64 bit version of R.
I have installed Tinn R.
Everytime I start R from within Tinn R it gives me the message
"The preferred R term was not defined. Do you desire to do this now"
I then tell Tinn R where the Rterm.exe and Rgui.exe are.

Hi,
I want to fit a regression model with one independent variable. The error
part should be fitted an ARMA process.
For example,
y_t = a + b*x_t + e_t where e_t is modelled as an ARMA process.
Please let me know how do I do this in R. What code should I use?
TIA

I typically annotate contourplots in the manner suggested. I agree that doing
it with a persp() plot would be more difficult but it's really quite
straightforward with either base or lattice graphics.

In perl, to get a substring matching a particular pattern can be

$x = ".txt";

So how to do the same thing in R?
Can someone provide me the code sample?
Thanks much in advance.

You noticed that the AIC increases while the p-value decreases as you
change the model and hold the data fixed. There would be more indication
of a problem if you instead noticed the same relationship between the
AIC and the p-value as you changed the data and held the model fixed.

Find what columns you're matching on,

Maybe that will shed some light on the issue.

There is no easy way to do this. It might be possible to customize vis.gam, to
be able to do this by using the same trick that allows you to add elements to
a 3D plot with `persp' (see help file for persp), but it would be quite a bit
of coding, I guess.
