How do I run an entire R code script in RStudio?
When I click on the Run button in RStudio, the code runs only on a line-by-line basis and I want it to execute all the code at once instead of running through line by line.
So far the only method I've tried that works is selecting the entire script and then clicking the run button. The other option is running line by line.
Is there an easier way to run the entire script with a single button or a shortcut?

To run the entire document press the Ctrl+Shift+Enter key (or use the Source toolbar button).
To quit R you can either use the RStudio > Quit pull-down menu command or execute ⌘ + Q (OS X) or ctrl + Q (PC).
RStudio 1.2 introduced the ability to send long running R scripts to local and remote background jobs. This functionality can dramatically improve the productivity of data scientists and analysts using R since they can continue working in RStudio while jobs are running in the background.
There is a lot of overhead in the processing because R needs to check the type of a variable nearly every time it looks at it. This makes it easy to change types and reuse variable names, but slows down computation for very repetitive tasks, like performing an action in a loop.
Or take a look at Rscript for running R scripts from the command line. In addition, in Rstudio you can run the entire script by pressing Ctrl+Shift+Enter without selecting any code. In addition, there is a shortcut to source the current script file (Ctrl+Shift+s), which runs the script without echoing each line.

Assuming your script is named "myScript.r", you can use something like source("myScript.r", echo = TRUE) to run the entire script.
