array
Hello, I have some files generated from microarray experiments. I used scan() to read the files, and assigned each file to a unique name with many rows and columns. Now I want to create a array (ArrayA) with unique names, and I can use ArrayA[1,2][[6]] to refer the data in each file. Is there any packages available for array of array? Thanks!

[LLVMdev] How to find the first block of each loop
...nction; 2) find the loop header with Loop->getHeader() APIs, and then insert the controller block before the header block of current loop. But I encounters problems when there multi subsequent loops in the following example, where there is no code between loops: for( i = 0 ; i < N; i++){ arrayA[i] = i + 1; } for( j = 0 ; j < N; j++){ arrayA[j] = j + 1; } for( k = 0 ; k < N; k++){ arrayC[k] = k + 1; } In this case, these loops have the same header block, so the previous method failed. And it seems the method of block_begin() returns the same value as getHeader(). Are ther...

How to apply a function to slices of multidimensional arrays, and not just iterating through single elements
Hello, If I want to apply some f(x) to such chunks of the the array dim(A)==c(d1,d2,d3,..,dk,...,dn) which are defined by A[...,ik,...] (ik belongs to {1,..,dk}), for now I use iteration via 'for (i in dim(A)[k]) f(A[...,k,...])' . Is there any more elegant approach, e.g like in 'apply' function which you can use on margin of the array. Just in my case I want the entire slice
