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

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

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