nls: different results if applied to normal or linearized data
...et, coefficient b was:

Is this supposed to happen? Which is the correct coefficient b?

is.null doesn't work
Hi,
What's wrong here?:
> v=c(`-`,`+`,1,`^`,`^`,NA,NA,"X",9,"X",2)
> i2=16
> v[i2]
[[1]]
NULL
> is.null(v[i2])
[1] FALSE
Is it a bug or have I misunderstood something?

Weighted association map
Could somebody program this kind of plot type to R, if none exists,

from character string to function body?
...-`(`+`(`^`(x,3),`^`(x,2)),1) # Here is the same as a character string.
Now I'd like to create a function using this string, something like this, but of course, this doesn't work:
S=as.expression(S)
F1<-function(x){S}
Is there some way to do this?

prcomp() and the lenght of PC:s

I would like to know whether there is some deeper rationale behind or is it just an established practice that the lenghts of principal components, giving for example by prcomp-function, are normalised to 1?

Can't interrupt R-processes in R OSX 2.6.2

Before I was able to interrupt R-calculations by pushing ESC, but now with R 2.6.2 (OSX Intel) it doesn't work. Is it bug or not?
