I have such dataset

I'm looking to count the number of times different words appear in a data frame, and then to remake that into a new data frame that shows the counts for each word.

For example, I have a data table like this:

I want to be able to count the number of times each word in the data appears for each Col1. While I could do things such as the number of items WordX = wordX, there are hundreds of passwords, making manual counting difficult, so I wonder if I have to use a for loop and a blank data frame in this situation to achieve something like this:

I would appreciate it if someone has a good idea about tackling this. Thank you!

I have been asked to remake the excel workbook to index where we keep the items. I have an excel sheet with a table ( excel table) that contains the information.

If the there the value in column 6 ="10" then that means the item is in box 10. then I need to get the right shelve, this is found by the numbers in column 7 (shelve) and 8 (rack). subsequently the information about the item has to be put in another sheet which gives a visual representation of the box.

I am struggling to get the desired result, does anyone have some suggestions?

What I am asking here is an algorithm question. I'm not asking for specifics of how to do it in the programming language I'm working in or with the framework and libraries I'm currently using. I want to know how to do this in principle.

As a hobby, I am working on an open source virtual reality remake of the 1992 first-person shooter game Wolfenstein 3D. My program will support classic mods and map packs for WOLF3D made in the original format from the 90s. This means that my program will not know in advance what the maps are going to be. They are loaded in at runtime from user provided files.

A Wolfenstein 3D map is a 2D square grid of normally 64x64 tiles. let's assume I have a 2D array of bools which return true if a particular tile can be traversed by the player and false if the tile will never be traversable no matter what happens in the game.

I want to generate rectangular collision objects for a modern game engine which will prevent collisions into non traversable tiles on the map. Right now, I have a small collision object on each surface of each wall tile with a traversible tile next to it and that is very inefficient because it makes way more collision objects than necessary. What I should have instead is a smaller number of large rectangles which fill all of the squares on the grid where that 2D array I mentioned has a false value to indicate non-traversible.

When I search for any algorithms or research that might have been done for problems similar to this, I find lots of information about rectangle packing for the purposes of making texture atlases for games, which packs rectangles into a square, but I haven't found anything that tries to pack the smallest number of rectangles into an arbitrary set of selected / marked square tiles.

The naive approach which occurs to me is to first make 64 rectangles representing 64 rows and then chop out whatever squares are traversible. but I suspect that there's got to be an algorithm which can do better, meaning that it can fill the same spaces with a smaller number of rectangles. Maybe something that starts with my naive approach and then checks each rectangle for adjacent rectangles which it could merge with? But I'm not sure how far to take that approach or if it will even truly reduce the number of rectangles.

The result doesn't have to be perfect. I am just fishing here to see if anyone has any magic tricks that could take me even a little bit beyond the naive approach.

Has anyone done this before? What is it called? Just knowing what some of the vocabulary words I would need to even talk about this are would help. Thanks!

(later edit)

Here is some sample input as comma-separated values. The 1s represent the area that must be filled with the rectangles while the 0s represent the area that should not be filled with the rectangles.

I expect that the result would be a list of sets of 4 integers where each set represents a rectangle like this:

1. First integer would be the x coordinate of the left/western edge of the rectangle.
2. Second integer would be the y coordinate of the top/northern edge of the rectangle.
3. Third integer would be the width of the rectangle.
4. Fourth integer would be the depth of the rectangle.

My program is in C# but I'm sure I can translate anything in a normal mainstream general purpose programming language or psuedocode.

So, I was trying to get all the pixels occupied by some text, but I realised pygame.surfarray.pixels3d doesn’t give the expected output.

Here is what I tried:

Let's say that I have a function returning a single value in some cases and multiple values (i.e. tuple) in other cases.

So I'm trying to make the addition of project easier for me with a json data.

Basically I'm creating blocks of projects and each project comes with an image, however even when the id == to the name I gave the image, the image does not render. Is there is any option for that or should I just give up on json files ?

• what I'm trying to re-do
• What I'm actually getting

The reactjs code

I have a very simple (albeit large) data frame with 2 numeric columns and 1 character grouping column, containing several NAs.

I am going to use iris as an example. Below, I just introduce random NAs in the Species column I want to use for grouping and coloring.

What I do here is to remake the Species column as a factor with "NA" (character) at the end. I make a palette with gray at the end, that I want to correspond to "NA".

I did a big no no and created a large table which included spaces in the names of the columns. I am trying to scan over this table and select particular pieces of information.
