Hi guys! I have a problem regarding a binary logistic hierarchical
model I am trying to use. The model contains various covariates that depend
on the location the response was measured at but do not depend on time
(year). I also have a spatial covariate that depends both on location and

This is not correct, svm() of course also accepts factors and then
builds a model matrix similar to lm(). But it won't accept, e.g.,
character vectors.

You could do this:

"This is some
text that I
would like to
have here."
x + 1
}

Hello.
I managed to solve the problem, here's what I learned:
The columns in data passed to svm need to contain only numeral values.
I simply assigned a number to each category of each feature. However,
there must not be a column where all the numbers are equal (there
mustn't be a feature with al

I understand I can put '#' to put comment line by line. But is there a

the every line?
Thanks.

Your question is much too broad for this list. It is not clear from

One can use

Dear R-users,

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) :
http://www.sas.com/apps/demosdownloads/sassysview_PROD_8.2_sysdep.jsp?packageID=000176
- I have installed it with Wine.

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.

Its a formula, not an expression -- but it will coerce formulas. Without ~
