Its a formula, not an expression -- but it will coerce formulas. Without ~
its no longer a formula.

This is really a GGobi issue not an R issue, but I believe their mailing
lists are down.
I think you are assuming that it is rggobi.dll that cannot be found, but
that is not what the message says. I would have expected Windows to give
you a dialog box telling you the exact problem, and I
No, I did not install ggobi at all (looks like I missed that step). I went
back and installed it and then reinstalled the R package and now everything
appears to be working as advertised. Thanks.

Thank you for your answer.
The big problems are :
- I don't have SAS
- I work on a linux system
But, I've just found a solution :
- I have downloaded SAS viewer (free) :

- I have installed it with Wine.

Dear R-users,
I am trying to get a simple plot for a linear model. The following function
does the job
of getting all the plots of the lm function but the main plot.
multivarplot -
function(...){
x1 - rnorm(10); x2 - rnorm(10); x3 - rnorm(10)
y - rnorm(10)
multivarfit - lm(y ~
say x is you rdata frame and y is the vector of column indices you
want to match to a condition:
x[apply(x[y]==Tom,1,all),]
still, i feel like there's probably a better way...

One can use

This is not correct, svm() of course also accepts factors and then
