Dear All!
I have a few question about proper syntax for fuzzy rules in sets
package (there is only little help about it):
1) how to use negation (NOT) operator there is only OR (||) in example
it is NOT, !!, !. I also assume that AND is
2) where it can be set. For example:
area %is NOT%

Dear All!
I'm looking for equivalent of Matematica function Which which works as
follows:
z = Which[x10,0.3, 10=x20,0.5, 20=x100,1]
where x is a vector
I can replace it with custom function with set of ifelse but I'm looking
for simpler and faster (much faster) solution
best wishes

Try this;
cut(x, breaks = c(0, 10, 20, 100), labels = c(0.3, .5, 1))

well function arguments are in square brackets. z is result (new
vector). I show Matematica syntax, but cannot explain what I expect. Sorry
The example is wrong because it can be replaced by R cut function. The
arguments are: condition,action and can be replaced by ste of ifelse
formulas:

Hello , I do not know anything abount Ubunto, but I found a Portable Ubunto for
Windows and since so many people
prefer Linux to Windows I decided to give it a try.
It runs very nicely, so I tried to load R, following Instructions in CRAN I
added the line

But, what may be more important.
This error was mentioned earlier on VISTA and WindowsXP, I use Ubuntu 8.04

unfortunately this problem is difficult do reproduce. If no, it would be
mentioned and removed earlier.
It probably heppens in some specific cirumstances. I I look for that

Not all that simple! It's one of those cases where you need
Hi

example of command:

Hi!
How to write in model's formula of type:
nls(y~k/(x^n), data=data, start=list(k=1,n=1))
i.e the problem is on x^n, I(x^n) generate error
thanks

Hi
I have the problem with fitting curve to data with lm and glm. When I
use polynominal dependiency, fitted values from model are OK, but I
cannot recive proper values when I use coefficents to caltulate this.
Let me present simple example:
I have simple data.frame: (dd)
a: 1 2 3 4 5 6
poly(a, 3)3 0.2236 0.4226 0.529 0.649562
