matR | Metagenomics Analysis Tools | Data Visualization library

I have a number of matrices that they all have the same type of elements but different lengths. Columns in all files are the same (lets call them "A" and "B") but rows between files are mostly the same elements but not always.

Here are some example data (in the form of dataframes)

I have a list which represents a tree being traversed in level order.

The first digit is the number of children and the second is its "level", starting at 1.

I want the program to output a list with the same elements as matr but in preorder instead.

Example

For the input: list(c(4,1), c(0,2), c(2,2), c(0,2), c(1,2), c(0,3), c(0,3), c(0,3))

The output should be: list(c(4,1), c(0,2), c(2,2), c(0,3), c(0,3), c(0,2), c(1,2), c(0,3))

I reckon the problem is with global variables? I've got it working in Python but not R when as far as I can see they are doing the same thing.

This is what I have:

My work uses WinSCP .NET assembly for SFTP transfers. After successful transfer files from server to local, I want to list only names (without paths) of the files and folders that were synchronized.

I'm working with PowerShell.

This is my tree structure of my remote files: /home/etc/
Folders: foldername1, foldername2. Under every foldername?, I have files matricule*.pdf

a matrix is given:

What is a good way to cast dlib::matrix into dlib::matrix? For example, dlib::matrix into dlib::matrix >?

Edit: I am looking for something more efficient than this:

i want to insert multiples rows, my first column (MATR) should be each number of the table @MATR

I'm trying to make a boolean selection that returns true only if the tests of the types 0,1,2, have a result greater than or equal to 60. The query does not cause me problems at the syntactic level but I can not get 1 from the result . What am I doing wrong?

I'm trying to compute the dimensions of an image from the points that are ordered from Top-Left, Top-Right, etc.. so I can later perform a 4 point perspective transform & warp. (Using opencvSharp & numpy.net)

I want to get the max-width and max-height as an integer from the NDarray but at this point it throws " Python.Runtime.PythonException: 'AttributeError : 'numpy.float32' object has no attribute 'ctypes''

Not quite sure how to go about this as a Novice and this my first time working with this OpencvSharp and numpy.NET.
