...mensional [actually an n-by-n-by ... by-n array]. Neither n nor d is known in advance. I want to bind the elements together in a higher-dimensional array. Toy example follows with d=n=3. f <- function(n){array(n,c(3,3,3))} x <- sapply(1:3,f,simplify=FALSE) Then what I want is ans <- abind(x[[1]] , x[[2]] , x[[3]] , along=4) [abind() is defined in library(abind)]. Note that dim(ans) is c(3,3,3,3), as required. PROBLEM: how do I do tell do.call() that I want to give abind() the extra argument along=4 (in general, I want along=length(dim(x[[1]]))+1)?

There is a new version of the abind package on CRAN (abind_1.1-0). abind() is a multi-dimensional generalization of cbind() and rbind() -- it can bind multiple 2-d matrices into a 3-d array, or bind 3-d arrays together, etc. In this new version the behavior of the function abind() has been enhanced slightly (it can now accept a...

I am trying to combine two arrays with different dimensions into one. For example The first one is 1 2 3 4 5 6 The second one is 7 8 9 10 The resulted one would be like , , 1 1 2 3 4 5 6 , , 2 7 8 9 10 I used abind to do this, but failed. Could somebody please let me know how to do this in R? Thanks so many. Suyan

Dear list, Is there a generalised form of rbind/cbind for combining matrices/arrays into higher-D structures? ie. if I have: a <- matrix(2,2,2) b <- matrix(3,2,2) how can I get array(rep(c(3,2), each=4), c(2,2,2)) ? It seems like this would be the job of a generalised abind function: abind(a,b, along=1) == rbind(a,b) abind(a,b, along=2) == cbind(a,b) abind(a,b, along=3) ==array(rep(c(3,2), each=4), c(2,2,2)) Thanks, Hadley

...q.test()) and then sum up the results, I get the answer I want. Clearly this is cumbersome, which is why I do it in Excel at the moment (I know shame on me). However, I really want to take advantage of the mosaic function in vcd. So what I have to do at the moment is create the tables above and use abind() (package:abind) to bring my two matrices together to form a multidimensional matrix. Example: > gh.abind = abind(g.mtrx,h.mtrx,along=3)> dimnames(gh.abind)=list(Sex=c("F","M"),Responses=c("Yes","No"),Factors=c("A","B"))> gh.abi...

I'm attempting to generalise a function that reads individual list components, in this case they are matrices, and converts them into 3 dimensional array. I can input each matrix individually, but want to do it for about 1,000 of them ... This works array2 <- abind(list1[[1]],list1[[2]],list1[[3]],along=3) This doesn't array2 <- abind(list1[[1:3]],along=3) This doesn't either array2 <- abind((list1[[1]]:(list1[[3]]),along=3) Any thoughts how I can make this work for larger numbers?

Hi, I would like to add rows to arbitrary tables within a 3dimensional array. I can directly add data to an existing row of a table: > x <- array(0,c(1,3,2))> x[,,1] <- c(1,2,3) And I can even add a row to the table and assign to another object. > y <- rbind(x[,,1], c(4,5,6)) and 'y' is what I want it to be:> y?? ?

If I have 2 n-dimensional arrays, how do I compose them into a n+1-dimension array? Is there a standard R function that's something like the following, but that gives clean errors, handles all the edge cases, etc. abind <- function(a,b) structure( c(a,b), dim = c(dim(a), 2) ) m1 <- array(1:6,c(2,3)) m2 <- m1 + 10 abind(m1,m2) ==> , , 1 [,1] [,2] [,3] [1,] 1 3 5 [2,] 2 4 6 , , 2 [,1] [,2] [,3] [1,] 11 13 15 [2,] 12 14 16 Thanks, -s [[altern...
