rscript:tldr:69868

This command is used to run an R script from the command line. Here is an explanation of each part of the command:

• Rscript: It is the command to run R scripts from the command line using the R interpreter. It is similar to executing an R script within the R console, but it allows you to run the script directly from outside the R environment.

• ${filename-R}: This part is a placeholder for the actual filename of the R script that you want to run. It is usually replaced with the actual name of the file when using the command. The -R after the filename represents that the script is written in R language.

In summary, the command Rscript ${filename-R} is used to execute an R script outside the R environment by providing the name of the script file after the command.
