Question

I’m using Emacs 24 on Windows to write some R code. Up until about 30 minutes ago, whenever I would write a new function, ESS would automatically indent the lines following the function declaration and pressing the tab key on a new blank line would jump me to the appropriately indented starting position inside the declaration.

EG:

foo <- function() {
    first line started here
    second line here.  .etc
}

Now, it is hard wrapping everything to the left, and not responding by automatically indenting after the function declaration or when I hit the tab key.

foo <- function() {
first line
second line
}

I’ve googled, but my google-fu is failing me on this. Anyone know how to restore default tab behavior to ESS in Emacs?

Answer 1

Try to add a space after “#”.
I don’t think ESS-mode handles # as a comment unless you have space after it.
