Dear R users,  I have 2 matrices dim(16x5) below and i want to write an algorithm that check the 2 matrices if they are isomorphic ones (Isomorphic matrices: if I change the rows or/and columns or/and zeros into 1 and 1 into zeros in a row(s) or column(s) are the 2 matrices identical). 0    0    0    0    0  1    0    1    0    1  0    1    1    0    0  1    1    0    0    1  0    0    0    1    1

Hi all, I want to find all the mappings of one graph in another graph, based on their vertex labels Is there any way to do this in igraph based on vertex labels. (as far as i know Igraph allows the subgraph isomorphism based only on vertex and edge colors) Eg: graph 1: x(1) x(2) x(2) y(3) y(4) x(1) z(5) x(2) graph 2: x(1) y(2) # the brackets contain the corresponding vertex ids i would like my

Dear All, Sorry for the typoes earlier, let me repost the question. Suppose I want to generate sequences of length 3 from two symbols {1,2}, we get the following 8 sequences 1 1 1 1 1 2 1 2 1 1 2 2 2 1 1 2 1 2 2 2 1 2 2 2 However, I do not want all these 8 sequences. I call two sequencs to be isomorphic if one sequence could be obtained from the other by relabelling the symbols. For example,

Dear R users, I have this problem with memory i guess  AA<-array(rep(0,96096000),dim=c(16,5,3003,400)) Error: cannot allocate vector of size 733.2 Mb can anyone help me,  Thanks in advance... [[alternative HTML version deleted]]

Is there a good reason not to allow matrix extents to be zero? I have been writing a function which fits glms under certain linear constraints. I fit the model with a reduced set of variables and then transform back to the original set. This involves operating on submatrices of the covariance matrix and subsets of the coefficients. Sometimes these subsets are empty. A zero-length subset of the

While playing with SLPVectorizer, I notice that it will happily vectorize cases involving extractelement/insertelement, but won't vectorize isomorphic cases involving extractvalue/insertvalue (such as the attached example). Is that something that could be straightforward to add to SLPVectorizer, or are there some hard issue? In particular, the transformation would seem to require casts of

Yes you are right ... an example is mandatory. So ... I have a matrix of 0 with just a single 1 per row and per column I need to extract all maximal 'diagonal' submatrices Let's say I have the following matrix A B C D E a 0 1 0 0 0 b 1 0 0 0 0 c 0 0 1 0 0 d 0 0 0 1 0 e 0 0 0 0 1 well I would like to get, for this example, the two following submatrices A B C D E

Dear R users, I want to check matrices when i change the order of the rows or/and the order of the columns or/and the combination of them i will give an example what i want  1  -1  1  1      1  1   1  1 -1  -1 -1 -1    -1 -1  -1  -1   1  1    1  1     1 -1    1   1 these 2 matrices are identical because i change the first row and make it third   1  -1  1  1      -1  1   1  1 -1  -1 -1

Dear R users, i want to put the results of a list to a for loop. i will give an example m1<-matrix(rep(1,15),ncol=5)   ind.sgn <- lapply(1:ncol(m1), combn, x = ncol(m1))  ind.sgn [[1]]      [,1] [,2] [,3] [,4] [,5] [1,]    1    2    3    4    5 [[2]]      [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] [1,]    1    1    1    1    2    2    2    3    3     4 [2,]    2    3    4    5   

Hi all, I'm working with a large data set (on the order of 300X300) and trying to apply a function which compares the elements of all possible 2x2 submatrices. There are rc(r-1)(c-1) such submatrices, so obviously the naive method of looping through the rows and columns is computationally unfeasible for my data set: for(i in 1:(nrow(data)-1)) { for(j in (i+1):nrow(data)) { for (m

Hi everybody, I'm looking for an optimal way to split a big matrix (e.g. ncol = 8, nrow=8) into small square submatrices (e.g. ncol=2, nrow=2) For example If I have > h [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [1,] 1 9 17 25 33 41 49 57 [2,] 2 10 18 26 34 42 50 58 [3,] 3 11 19 27 35 43 51 59 [4,] 4 12 20 28 36

Hi, I have a matrix of say 1024x1024 and I want to look at it in chunks. That is I'd like to divide into a series of submatrices of order 2x2. | 1 2 3 4 5 6 7 8 ... | | 1 2 3 4 5 6 7 8 ... | | 1 2 3 4 5 6 7 8 ... | | 1 2 3 4 5 6 7 8 ... | ... So the first submatrix would be | 1 2 | | 1 2 | the second one would be | 3 4 | | 3 4 | and so on. That is I want the matrix to be evenly divided
