R CMD on Windows 7 Error - “R” is not recognized as an internal or external command,

Question

I\'m exploring package building on Windows 7 but have been running into trouble after reaching the Command Prompt stage. The following thread appears to be on the same topic

Answer 1

In the .bat file add a line of code specifying the path of the folder where R is installed and then give the path of the script as follows -

@ECHO OFF
PATH C:\Program Files\R\R-3.5.1\bin
R CMD BATCH D:\project_abc\helloworld.R

Following this, run the .bat file and you will see the code in the script will run smoothly.
