The provided save_crs function saves a series of high-quality plots to files, with filenames dynamically constructed based on the inputs. Here's an explanation of what the code does:

1. Function definition:
   The function save_crs takes three arguments:

   • checks: A list containing at least a sublist or element named linearity. This likely holds plot objects to be saved.
   • suffix: A string that gets appended to the filenames.
   • ass_dir: A string representing the directory path where the plots will be saved.

2. Iteration with purrr::walk2:

   • walk2 from the purrr package is used to iterate over two parallel inputs:
     • The names of the elements in checks$linearity (via names(checks$linearity)) and,
     • The elements in checks$linearity themselves.
   • For each pair of the element name and the plot object (.x = name, .y = plot), a function is executed.

3. Call to save_plot_hq:

   • Within the iteration, the function save_plot_hq is called, which is assumed to be a custom or external function used to save a plot to a file with high quality.
   • The arguments passed to save_plot_hq are:
     • filename: The path to save the file, constructed by combining the ass_dir directory, the prefix "cr_", the name of the current element (.x), the provided suffix, and the file extension ".png".
     • plot: The current plot object .y.
     • width, height, dpi: Parameters specifying the dimensions (8x6) and resolution (300 DPI) of the saved image.

Summary:

This code iterates through the linearity elements in the checks object, retrieves their names and corresponding plot objects, and saves each plot as a .png file with a specified resolution into the ass_dir directory. The filenames are dynamically created by incorporating the element names and an additional suffix.
