How to stop ESS from asking for "R starting project directory"?

Question

Every time I execute all code blocks in an org mode file that contains an R code block (using org-babel-execute-buffer with C-c C-v C-b), ESS pauses to ask for R starting project directory, which seems to default to the current directory of the .org file. This prompt causes delays as there is often lengthy initialization process and other code blocks before encountering the first R block. So one has to come back after a minute or two to make it continue.

My question is:

Is there a way to disable the prompt for R starting project directory and always have it defaulted to the current directory?

Answer 1

You want to set ess-ask-for-ess-directory to nil. And, maybe, also check the value of ess-startup-directory, which should also be nil to use current buffer's default directory.
