Help me create a hyper-structure

It seems you were right.
Now I can easily access my struct and substruct like this

# all.str[[1]]] Gives access to the first struct of per.sr.struct which containts 101 times the xorder,yorder,estimation.sr
# all.str[[1]][[2]] Gives access to the second substruct of all.str[[1]]
# all.str[[1]][[2]][[3]] Gives access to the matrix.

Now I would like to ask you if in R cran I can make struct assignments like this 


    all.str[[i]]<-TempApproxstruct


where all.str[[i]] is  a list that contains 100 times the
 $ :List of 3
  ..$ xorder       : int 0
  ..$ yoder        : int 0
  ..$ estimation.sr: logi [1:256, 1:256] NA NA NA NA NA NA ...
 $ :List of 3
  ..$ xorder       : int 0
  ..$ yoder        : int 0
  ..$ estimation.sr: logi [1:256, 1:256] NA NA NA NA NA NA ...
.... and so on

where str(temp.per.sr.struct) is a list that contains 100 times the
 $ :List of 3
  ..$ xorder       : int 0
  ..$ yoder        : int 0
  ..$ estimation.sr: logi [1:256, 1:256] NA NA NA NA NA NA ...
 $ :List of 3
  ..$ xorder       : int 0
  ..$ yoder        : int 0
  ..$ estimation.sr: logi [1:256, 1:256] NA NA NA NA NA NA ...
  [list output truncated]
...and so on.

Will R understand this kind of assignments or not?

I would like to thank you in advance for your help
Best Regards
Alex

Dear all 
I would like to have in R a big struct containing a

smaller struct. 

1) I would like to have a small struct with the

following three fields

xorder (an integer ranging from 0 to 20)
yorder (an integer ranging from 0 to 20)
estimated (a 256*256 matrix)

2) I would like to have 10 elements of the struct

above

for that I wrote the following:

Estimationstruct <- function ( xorder, yorder,
estimated) {
? list (xorder= xorder,
yorder=yorder,estimated=estimated)
}

per.sr.struct <- replicate(10,
? ? ? ? ?
???Estimationstruct(0L,0L,matrix(nrow=256,ncol=256)),
???simplify=FALSE)

That one worked.
per.sr.struct contains 10 elements and each one of

that contains 1).

all.sr.struct
<-???replicate(20,per.sr.struct,simplify=FALSE)

The idea is to have 20 all.sr.stuct and each element
to contain one per.sr.struct.

? I think you just missed simplify=FALSE in the last
step ...
