cpm | fast CPAN module installer , which uses Menlo

For improving the speed, you can see Numba, which is useable if you use NumPy a lot but not every code can be used with Numba. Apart from that, the formulation of the equation system is confusing. You are solving 3 equations and adding the result to a single dydt list by 3 elements each. You can simply create three lists, solve each equation and add them to their respective list. For this, you need to re-write my_system as:

I thought about your implementation and I found a quick way you could achieve what you want. In short, you will need to install webpack, which is a module bundler (it means that its main purpose is to bundle JavaScript files for usage in a browser). If you have npm already set up, you can execute this command in your project:

you can use $project to format your output so instead of $set and $unset use $project like this

That syntax for a named vector doesn't work because R functions (including c()) don't require quotes for argument names:

Your code contains several errors which results in Undefined Behavior. I'll highlight two in this answer that could explain the behavior you observe.

A bool, like most objects, can't be used to communicate between threads without synchronization. You have two threads, one that writes to and one that reads from the same variable, which is a data race. Having a data race means the program has Undefined Behavior. You are not allowed to read from an object that another thread might be simultaneously writing to.

The second error is due to the progress guarantee. This guarantee makes it Undefined Behavior to have an infinite loop with no side effects.

One possible result of this UB is that the compiler can see that once the thread enters counter it never changes *click, so it can assume that *click remains constant for the duration of the execution. bool is not allowed to be shared between threads without synchronization, so this is a valid assumption on the compiler's part.

The compiler could also see that while (*click) {} has no side effects, so it could assume *click is eventually false as the loop may not be infinite.

Since the compiler can assume *click is a constant, and *click must eventually be false, it can assume *click is always false.

The easiest solution to this problem is to use a std::atomic instead of a bool. This wraps a bool in a way that makes it shareable between threads.

However, it looks like you are using non-synchronized objects for many other inter-thread communication applications. You'll have to address each of these.

Multithreading is very difficult to get right, it isn't something that should be learned by trial and error. Consider getting a book on the topic.

You just need to "wrap" you if statement with another one in order to handle the grand total using size which returns the number of rows in the partition.

Using the superstore you can create a calculated field like this:

It turns out I was simply using the wrong target. Interfaces don't include any source files and thus won't generate any meaningful compile_commands.json.

What I was looking for is the object target which solves my issue completely.

Just for the reference, this is how the "correct" CMakeLists.txt would look like:

You could use the following code. First make a single dataframe, with an extra columns specifying which is pre which is post. Then generate a plot facetting the PrePost var as well.

If you only want cpm, bidder, adUnitCode in the resultant object then you can easily do using Object.entries, reduce, and map
