Re: [R] dimnames in an array(I'll be grateful if this message will be passed to all list users)
res3 = Profile.LS(fhn, data=data2, times=times, pars=pars,
coefs=coefs, lambda=lambda, out.meth='nls',
control.in=control.in, control.out=control.out)
#Rather than parameter estimates, as with the single replicate
analysis, this produces the error:
Error in as.array.default(Y) : attempt to set an attribute on
NULL
This happens for me when I omit the basisvals argument to Profile.LS().
Profile.LS ought to catch this directly.
Profile.LS also produces a slew of warnings while running the example in its
help file. E.g.,
Warning in dim(weights[whichrows, ]) == dim(diffs) :

Hi,
Thank you for the suggestions.
I've attached the code in the text file "test"; to run this one needs the
CollocInfer package(available under R 2.14, now I think if you have 2.14 on
your system you can download CollocInfer from CRAN).
I've tried the 'error' options you suggest; using the syntax
"dimnames(data2)[1:2]" does seem to give an improvement of the attributes of
the array,
But even with the attributes seeming to be in as good order as they might
be(i.e., each boxcar, [[1]],[[2]],[[3]] contains the correct number of names),
rerunning the analysis with the revised array returns the same error.
traceback() gives
4: `colnames<-`(`*tmp*`, value = c("V", "R"))
3: objective(.par, ...)
2: nlminb(coefs, SplineCoefsErr, gradient = SplineCoefsDC, hessian = Hessian,
control = control.in, times = times, data = data, lik = lik,
proc = proc, pars = pars)
1: inneropt(coefs = DEfd2$coefs, times = times, data = data2, lik = lik,
proc = proc, pars = spars, in.meth = "nlminb", control.in = control.out)
To my (untrained) eye, this points again to some kind of mismatch between the
array 'data2' and its dimnames.
Again I'll be grateful if anyone can see what the problem is.

A lacuna in the English language, not in R: though perhaps Prof Ripley's

I don't believe I made any prescriptions about length(dimnames[2]) so I have no
idea what you mean here about it not agreeing with me.
Also, there's almost no chance that's valid syntax: it should throw a 'closure
not subsettable' error unless you over-wrote the name of a very important
function (which you should not do).
And I believe I told you that you want double brackets here.

No! Double brackets.

I'm travelling currently so I can't track this down (no wifi) but I'll try
later. In the meanwhile, see Bill Dunlap's suggestions.

Again -- your code ("dimnames[2]") looks like nonsense -- I think you've
overwritten a function that you shouldn't have.

Dimnames must have lengths which correspond to the dimensions of the underlying
array -- that is
dim(a) == sapply(dimnames(a) length)
Nothing else really makes sense. The only way to change the lengths of the
dimnames is to reshape the array.

Re: [R] dimnames in an array(I'll be grateful if this message will be passed to all list users)
Michael,
Thank you for suggestions;
it seems to me that there's a fundamental lacuna with respect to names of a
three dimensional array:
that is, rownames fits dimension 1, colnames fits another dimension(that is, 3,
if I read it correctly),
but there is no specific name for the third dimension. I've tried "setnames"
thinking that this would be appropriate
for naming the sets, but there is no such R function.
On the other hand you're right, the suggestion
            dimnames(data11a)[[2]]=c("V","R")
doesn't ameliorate the analysis: while now dimnames(data11a)[[2]]
comes out as
[2]
returning to the original analysis the same error comes up, that is, that the
length of dimnames[2] doesn't agree with thee.
'array extent' -- that is, even though the boxcar contents are two in number,
it evaluates the analysis on the basis of the
dimnames(data11a)[2] value.
I'm using colloc infer (available under R 2.14) and trying to do the
FHN(FitzHugh Nagumo) analysis in section 9.1 of the manual; it's very complex
work, but I doubt the program is in error.
It seems to me in any case that, if R demands that the length of 'dimnames[2]
must be equal to the array extent, then there must be a way to make the length
of the names equal to the extent of the array, am I right?
Otherwise R would be inconsistent with itself, like Nomad on Startrek, and I've
never seen a case where it was thus.
This is again why I ask if others with extensive experience with dimnames of an
array have seen anything similar.
Certainly someone might know what is the significance of the dimnames of the
array, how much can the length of them be altered for use generally?
regards,
A

You could do this:
dimnames(data11a)[2] <- list(c("V","R"))
but I'm not sure that's any clearer. To keep the metaphor rolling (get
it!), list() puts your stuff in a boxcar so now you can put it
directly on the train.

Where is this inneropt function from? It could be an error in that. If
it's from a package, give me the name and I'll take a look at it and
you can also contact the maintainer: get contact info using the
maintainer() function.
Also, some of the advice here will probably be helpful in seeking follow-up:

Re: [R] dimnames in an array(I'll be grateful if this message will be passed to all list users)
Hi Michael,
Thanks for help on double brackets: I wasn't aware of this use of them.
I went back to readjust my array so the dimnames(data11a)[[2]] would have two
elements, and remade the array to include the new dimnames:
dimnames(data11a)[[2]]=c("V","R")
so that inside the second car of the train would
be two items?
There seems to be no way to define dimnames(data11a)[2] to be two elements
rather than one[as you say we have no way to combine the elements of the train
except using the train]. So having tried to do what I can to make the middle
element of the list to two rather than one, I rerun the analysis with the same
result.
if I read the thing right, regardless of how I define the "inside" of the
boxcar, the analysis that I referred toÂ
         res11a = inneropt(coefs, times=times, data=data11a,
lik=lik,
         proc=proc, pars=spars, in.meth='nlminb',
control.in=control.out)Â
still won't look at the 'contents' of the car, but gives the same message:
         Error in `colnames<-`(`*tmp*`, value = c("V", "R"))
:
         length of 'dimnames' [2] not equal to array extent
I've tried a couple of other things like, after defining the second boxcar as:
         dimnames(data11a)[[2]]=c("V","R")
then
          dimnames(data11a)[2]=list(dimnames(data11a)[[2]])
but this last generates an error.
Somehow I think that that the clue to the thing is in the error message: what I
see[ with my untrained eye] is that there should be some way to reconcile the
three-- colnames, dimnames and the array- to a greater degree than their
present agreement.
Am I right?
regards,
RussellÂ

I believe you are looking for
length(dimnames(data11a)[[2]]) # 2
Look into the difference between `[` and `[[` for subsetting a list.
See ?Extract for the gorey details, but I like my little train
metaphor:
If the list "x", is a train: x[2] is the "sub-train" consisting only
of the second car, while x[[2]] is the contents of that second car.
Hence we can do x[1:3] to give a well defined train, but not x[[1:3]]
because we have no way to combine the elements of the first three cars
other than using a train.

Michael

[R] dimnames in an array(I'll be grateful if this message will be passed to all list users)
Hello,
I'm hoping someone with a wide experience with R may be able to see
what the program is trying to tell me.
I've got an array:
y1=rnorm(41,0.2)
y2=rnorm(41,0.2)
y3=rbind(y1,y2)
data11<-array(0,c(41,2,2))
data11[,1,]=y3
data11[,2,]=y3
rownames(data11)<-rownames(data11, do.NULL = FALSE, prefix = "Obs.")
colnames=c("V","R")
varnames=c("one","two")
dimnames(data11)<-list(rownames(data11), varnames, colnames)
data11a<-as.array(data11, dimnames=dimnames(data11))
The analysis that I would like to do with R(CollocInfer) runs as
follows(I print for the sake of introduction here though to run this
line of code requires extensive setup)
res11a = inneropt(coefs, times=times, data=data11a, lik=lik,
proc=proc, pars=spars, in.meth='nlminb', control.in=control.out)
The response I get is
Error in 'colnames<-'('*tmp*', value = c("V","R")) :
length of 'dimnames' [2] not equal to array extent
It seems to me that there is a fundamental match of 'dimnames' with
the array that is being referred to.
I have learned that the normal length of dimnames for an array is one
for each element in the list: thus as I've set up the array, the
length(dimnames(data11a)[2]) gives me
[1]
I would like to ask :Is it not evident from R's response that there is
some other possibility for the dimnames[2] of the array?
If so, what is it?
regards,
A
