XML: Reading transition matrices into R
Hello, from a software I have the following output in xml (see below): It is a series of matrices, for each age one. I have 3 categories (might vary in the application), hence, 3x3 matrices where each element gives the probability of transition from i to j. I would like read this data into R (preferably in a list, where each list element is one of the age specific matrices) and - after altering

[PATCH nbdkit] tests: Convert some tests to use nbdsh instead of qemu-io.
Very much a work in progress as there are still many tests using qemu-io which are candidates for conversion. You'll notice at the end of test-full.sh that the new test has some duplicated code which looks as if it ought to be refactored into a Python function. When I tried to do that, I got loads of strange Python problems which may indicate bugs in nbdsh itself or problems with my

transitions in R
Hi, All. I'd have a set of data in an array: process <- c( 5 , 7 , 4 , 1 , 4 , 1 , 4 , 1 , 4 , 4 , 1 , 5 , 4 , ...) and I'd like to know the number of transitions in this data. I calculate transitions as the number of times a number follows another number. thus, something like this would be a 1 deep transition: 1 --> 1 : 10% (and actual number of 1 --> 1 occurrences) 1 --> 2 : 2% 1 --> 3 : 23% ... 2 --> 1 : 2% 2 --> 2 : 8% (etc.) of cou...

Operand bundles and gc transition arguments
As part of adding `"deopt"` operand bundles, we're aiming to change RewriteStatepointsForGC (called RS4GC henceforth) from rewriting existing `gc.statepoint` calls to transforming normal LLVM calls and invokes into `gc.statepoint` calls and invokes (i.e. to do PlaceSafepoints + RS4GC in one step). This will make `gc.statepoint` an artifact of the gc lowering strategy that only

Constructing the transition pair using loop function and paste()
Hi all, I'd like to thank those who helped me with my previous loop function question with agents/events. I have solved the problem with the advice from this community. I have now moved on to the next step, which requires me to find all the transition pair within an event. A sample data and the R commands I've written are as follow: x <-

for loop vectorization
Hi, I am still not familiar with vectorization. Could you help with making this for loop more efficient? The code is trying to make a Q matrix for a multidimensional state space with specific conditions. thanks Mira tmp = 0:(maxvals[1]) for(i in 2:nchars) { tmp <- outer(tmp, 0:(maxvals[i]), FUN="paste", sep=".") } states = tmp stateidx = array(1:length(states),
