The sample command can be used to simulate classic probability problems like drawing from an urn with and without replacement, or creating random permutations.
Note that throughout this example, set.seed is used to ensure that the example code is reproducible. However, sample will work without expl...
To calculate the sum of terms (of type float, int or big integer) of a number list, it is preferable to use List.sum

Sum of complex numbers
In this example, we declare a list of complex numbers and we calcu...
One of the most critical parts of dealing with NMS code is being able to support mulitple Minecraft versions. There are numerous ways to do this, but a simple solution is to use this code to store the version as a public static field:
public static final String NMS_VERSION = Bukkit.getServer().getC...
Create a new folder called MyClasses and create and add the following class

New-S3Bucket -BucketName trevor
The Simple Storage Service (S3) bucket name must be globally unique. This means that if someone else has already used the bucket name that you want to use, then you must decide on a new name.
Set-Content -Path myfile.txt -Value 'PowerShell Rocks'
Write-S3Object -BucketName powershell -File myfile.txt
Uploading files from your local filesystem into AWS S3 is easy, using the Write-S3Object command. In its most basic form, you only need to specify the -BucketName parameter, to indicate ...

Remove-S3Bucket -BucketName powershell -Force
In order to remove a S3 bucket, you must first remove all of the S3 objects that are stored inside of the bucket, provided you have permission to do so. In the above example, we are retriev...

This will be our example data frame:
color name size
0 red rose big
1 blue violet small
2 red tulip small
3 blue harebell small
Accessing a single column from a data frame, we can use a simple comparison == to compare every element in the column to the given...
This will be our example data frame:
color size
name
rose red big
violet blue small
tulip red small
harebell blue small
We can create a mask based on the index values, just like on a column value.
rose_mask = df.index == 'rose'
df[rose_mask...
Let's consider this example, that outputs the squares of the numbers 3, 5, and 7:
let nums = [3, 5, 7]
let squares = nums.map(function (n) {
return n * n
})
console.log(squares)
Run in RunKit
The function passed to .map can also be written as arrow function by removing the function keywor...
