The command "R -d ${debugger}" is used to run R, a programming language and environment for statistical computing and graphics, with a specified debugger.

Here's what each part of the command means:

• "R" is the command to start the R program. It launches the R interpreter and allows you to execute R code.
• "-d" is an option or flag used to specify a debugger.
• "${debugger}" is a placeholder variable that should be replaced with the name of the debugger you want to use. The exact name will depend on the available debuggers on your system.

Overall, this command combines the execution of the R program with the usage of a specific debugger to help with debugging and troubleshooting code. By specifying the debugger, you can track and analyze the execution of R code in order to identify and fix any issues or errors.
