There are two things causing this.

You're adding the observed values of Occurences to your prediction dataset, then using those observed values as your y aesthetic in geom_ribbon(). You should instead set y = fit to use the predicted values.
You're generating predictions using the observed values of your covariates, which will introduce noise. Instead, set each covariate at its mean in your prediction set.

Also - are you trying to plot the observed values using geom_point()? If so, set data = Rabbit_ACT to use the original data there for that geom. Otherwise, to plot the predicted values, change the mapping to y = fit there as well.

You might be looking for a slice type: []u8 or []const u8. A slice type contains a pointer and a length, so the struct does not actually directly hold the string's memory, it is held somewhere else. https://ziglang.org/documentation/0.9.1/#Slices

Build variable length arguments array for @call

I've recently started learning Zig. As a little project I wanted to implement a small QuickCheck [1] style helper library for writing randomized tests.

However, I can't figure out how to write a generic way to call a function with an arbitrary number of arguments.

Here's a simplified version that can test functions with two arguments:

This is because readToNumberList is returning a pointer to stack memory that goes out of scope, which is undefined behaviour and not yet caught in debug builds.

Mapping a string into a 2D Array for a "zig-zag" effect

Asked 2022-Jan-30 at 18:18

first post, new to coding in js. I am trying to create a function that takes a (2) string array as an input such as ["coderbyte", "3"], the first string being any random string. The second string represents the number of rows the function should create in a 2D array. The function should then print the first string in a zig zag pattern such as the following:

ANSWER

Answered 2022-Jan-30 at 18:18

Since "All help is much appreciated", here's a completely different way of doing a zig-zag effect.

It comes from noticing that the zig zag pattern uses every 4th character in the top and bottom rows, but at different offsets/phases (0 for the top row and 2 for the bottom row), and the middle row uses every 2nd character (starting from the offset 1).

QUESTION

Displaying only 3 lines and deleting old ones

Asked 2022-Jan-27 at 14:45

The script is working pretty but in terms of performance it doesn't delete the lines in the past, which means it will probably crash when a lot of new candles appear on the screen. That's what I'm trying to solve.

How do I make it display only 3 lines and delete the old ones? Something like the one below, but I don't know exactly how to accomplish it. I know I have to do it with an array, but not sure how.

...

ANSWER

Answered 2022-Jan-27 at 14:45

Not really the case; Pine has an automatic garbage collector that deletes oldest lines dynamically when new ones appear specifically for performance. So strictly speaking, you don't need to do any cleanup by yourself unless you specifically want to. If you do:

At max Pine can leave around 500 lines on your chart, which in this script is indicated via the max_lines_count=500 parameter in the indicator function. The easiest limit to implement is just setting max_lines_count=3 (note that it won't be exactly 3, but around 3).

The better way is via arrays. It's easier to use the built-in line.all variable that returns an array with all lines on the chart:

Correct BigInt Fibonacci Implementation in Zig Lang

Asked 2022-Jan-21 at 18:22

I am new to Zig Lang, and I was searching for an existing implementation for Big Int Fibonacci to no avail.

So, I went through the source code of Zig Lang, Specifically Big Int Source & Big Int Tests, to figure out how to use the Big Int functionality and then winged the desired solution.

It's sort of a tradition I follow while trying to gauge the speed of a language before learning. Like I did with: Big Int Fibonacci Benchmark for Go & Rust. (N.B. I didn't have to write the solution for those languages!)

Now, here's my implementation in Zig, for your kind perusal:
