Survey | survey web app implemented using Django framework | REST library

Short version: I need is to get a results column r like this, ideally using dplyr (but happy for base R as well):

I have a dataset that has this structure (lots of questions asked to survey respondents) that I want to reshape from wide to long:

I've been working on some survey data using the survey package. I read the documentation available on post-stratification and calibration, however I got stuck trying to calibrate the sampling weights on a total known for the population that is not the population total.

To make my self clear I prepared an example: Let's say I have income information for a sample stratified by sex, which lets me create the svydesign object:

I have a template tags that takes ID on template and returns a list, I want to check the list if the variable is available and make checkbox input checked.

I have a string in which I'm trying to extract a URL from. When I run it on this RegEx site, it works fine.

The Regex Pattern is: http:\/\/GNTXN.US\/\S+

The message I'm extracting from is below, and lives in a column called body in my SQL database.

I have a dataset of survey responses similar to this:

I have a Data Frame with Survey Data and want to create crosstables between every dimension and diagnosis. I succesfully did this with dplyr and janitor:

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 very new here, but I've always had so much help going trough other peoples questions and answers that I thought I'd try if anybody could help me out.

I think I might just be looking for something that is impossible, but I hope not! Perhaps some of the geniuses here know a way how to, haha.

So, I've created a stacked barplot that shows per location (x-axis) the amount of fish we encountered during surveys (y-axis). I am focused on herbivores, so in the barplot, the total count of herbivores/omnivores is coloured, while the carnivores are white. In my entire research, each location has had one type of color assigned to it within all the graphs, so I did that here as well. This results in 6 different coloured bars per graph with a white area stacked on top that represents the counted carnivores. Now I was wondering: is it possible to represent all 6 of the blue colours in the one square/key-entry in the legend? I now picked the blue color in the middle part of the color scale to represent the herbivores, but as this only corresponds to 1 location it might not be the best solution.

The graph that I created. I've added two errorbars: the solid line for all fish that were counted and the dashed lines for just the herbivores.

I already made a completely new legend for this graph, so I would only have 2 entries (squares in the legend) instead of 7 (6 locations + the carnivores). The code I used to create this picture is as follows:
