I am looking to save this ggplot2 chart below using the ggsave function after I've added a logo to it

I wish to populate various collection views and table views with data from a json file. However I do not know how to write that JSON file.

here is the data I wish to populate:

• 2 sectors : "data" and "developers"
• each sector contains a number of items:

for "data" :

• "Data Scientist",
• "Business Intelligence Analyst (BIA)",
• "Database Developer",
• "Database Administrator",
• "Data Engineer",
• "Data Analytics Manager",
• "Data Security Administrator"

for "developer":

• "APL",
• "BASIC",
• "Eiffel",
• "Frink",
• "Lisp",
• "Pascal",
• "Python",
• "Ruby",
• "S-Lang"

How would I need to organize the data so I can later retrieve them ?

I'm working on a shiny app which contains an image, and then lets you draw a transect line on that image.

The current app lets you double click to create a starting point for the transect, and then it will use the mouse hover position to create a 'end' point for the transect. As you move the mouse, the transect updates with the new mouse position.

What I'd like to do is be able to double click again, and this would 'confirm' the end point of the transect, so the transect would now be fixed in place, and would not respond to mouse hover. Is there someway I can do this?

I am trying to use my own image for geom_point, something I can just read in. I am aware geom_point allows you to choose many shapes (well over 300) by simply writing shape = 243 but I want my own image such as a logo.

When I have not specified color = factor(Name) then it works as expected. When I do specify the colour of the line then the image becomes a solid single colour. I want this line to be coloured so is there any way around this? Thanks!

This image should be filled using smaller images:

Is it possible to remove the background of images with the magick package?

I know how to use edge detection with Gimp/Inkscape to crop out silhouettes; however, I'm looking to automate the process for a large batch of images with R.

My ultimate goal is to use the ggimage package to plot these images as x,y coordinates but the background of these images is currently overlapping the plot (the dog compared to fink)

I'm new to using predicates and not sure if I'm understanding it properly. I have an abstract employee class in which hourly and salary employee's are created separately. My issue relies in my EmployeePredicate.java class where I am unsure how to check whether it is an hourly employee and to return true or false.

I need to create a different predicate for all of the following conditions:

All employees, Hourly Only, Salary Only and Fulltime Only.

So far I am only trying to get the "Hourly Only" Predicate to work properly first and think I could figure out the rest after that. I am unsure what to put after the 'p' to check which type of employee it is. What I have currently is:

The magick package documentation shows how to make a mosaic of a vector of image objects:

I am new to python and am looking for guidance on the task I am working on.

I am importing a csv file that looks like the list below.
