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

Yes, please remove the Transition class and create a map structure in
State instead of TransitionSet.

[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

My problem is that there are 16 possible transitions, but not all possible
transitions occur at each time step. Therefore, don't think I could do
something easy like create a table for each time step and add them together,
for example:

1 1 1 0

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.)

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:

But they provide different grades of transitivity, which is where all
the confusion lays.
smp_mb() is strongly/globally transitive, all CPUs will agree on the order.
Whereas the RCpc release+acquire is weakly so, only the two

Hi,
I think you overthought this one a little bit, I don't know if this is the
kind of code you are expecting but I came up with something like that:
generate_transition_matrix <- function(data, n_states) {
#To be sure I imagine you should check n_states is right at this point
transitions <- matrix(0, n_states, n_states)
#we could improve a little bit here because at step N+1 source is dest
from step N
#but it would not be as readable
for (k in 1:(length(data) - 1)) {
