I would like to store data that transverse several levels of hierarchy.

For example:

A data structure that stores cars may store the colour, age and other aspects of each vehicle.

The question is: does it make more sense to use dictionaries or OOP for this problem? And how do I print such a structure into a table format?

Please imagine that I don't know "a priori" the number of levels (depth) of the data structure. Please check the picture attached.

Cheers,

Pedro

Inputted x, y, and z coordinates will output three graphs: an x-z graph sliding along the y axis, an x-y graph sliding along the z axis, and a y-z graph sliding along the x axis. I position the lines based on the percent by which the user has slid its corresponding coordinate on the slider tool. See below (don't be alarmed by how the coronal and transverse views are switched):

However, as you can see, the y-coordinate is low, so the line is out of the bounds of the figure. The issue is the lines are positioned relative to the window rather than relative to the plot. Therefore, I would like to get the size of the figure within the window to correct for this issue. I have not found any documentation on how to find the dimensions of a figure within a window as opposed to the whole window—how would I approach this? Thank you! See my code below to see how each individual plot is visualized:

I recently started using the stars R package. I'm struggling with reassigning NA values to "Unknown". I found a potential solution here, but it doesn't seem to work on NAs. Any suggestions to fix this issue are greatly appreciated. for some reason SO doesn't like huge chunks of code without adding more information, so i'm adding some random text at the bottom.

Here's the code that I used:

I need to filter by a time period that includes midnight (i.e., 00:00:00). I am using dplyr to filter and all filters are working except the one including midnight (i.e., 21:00:00 - 03:59:50). I am sure this is a simple fix, but I can't figure it out. I am also unsure of what else to add to this post, but I keep getting the warning that I should add more detail because my post includes mostly code. Any advice? Thanks

I have a multiplatform library to do few APIs calls with Ktor (2.0.0-beta-1)

I need to search in a table a value and reurn the value of the last column of the corresponding row (I can transverse rows and columns if it is going to simplify the functions). For example, I have the following table and when I give as the search value 75, I want to have the value 204 (value of the last column of the same row). The last column can be also moved to be the first one, in case it helps the function. I tried with Index and Match and Lookup but these functions need one column array to search into.

Here is a basic function call I would like to do, As you can see below in the signature, I would like to have the default value in s be the length of the string passed in for convenience. Is it possible to do this in python? Or some version of this?

I would like to extract the unit of measurement (decimal degrees, metres, feet, etc.) from a spatial object in R. For example, if I have an SF data frame that uses the WGS84 co-ordinate reference system (EPSG:4326), I would like to be able to determine that the co-ordinates are specified in decimal degrees. Similarly, I'd like to be able to determine that UTM co-ordinates (e.g. EPSG:32615) are specified in metres.

I have tried using the st_crs() function from the sf package, which returns the co-ordinate reference system in well-known text format. However, I'm struggling to be certain that a regex that extracts the unit of measurement from that well-known text will operate reliably for a wide range of co-ordinate systems.

Is there an existing function that returns the measurement unit for a spatial object?

For example, the following code produces an SF data frame that uses the WGS84 co-ordinate system:

I am trying to follow this approach for identifying transverse nodes. Unfortunately I am getting this error:
