If there is an error in your code then ESS shows a message in the minibuffer and you can investigate it by pressing C-c `. The advantage of this approach is that it sources all the functions and produces nothing in the R buffer. Then you can simply load this file using load ESS file option (shortcut C-c C-l). You can do this by keeping all your functions in one file called 10code.R for example. When sending code to R, it is advisable to keep distinction between functions and R statements. The relevant shortcuts are C-x 3 for splitting windows vertically, C-x 1 for making the current buffer the only window and C-x 2 for splitting windows horizontally. Then on the left you can have a source code, which will be sent to the R process on the right. So for example you can scroll to your previous command and put the cursor on it, press Enter and it will be reproduced.Īfter starting R process, we suggest dividing emacs in two windows (Emacs terminology). The improvement on the usual prompt is that it is also simple text file containing everything R produced. What you get is similar to usual R prompt: Select the directory (you can use Tab to complete long directory names) and press Enter. This will probably be the most used shortcut for first time Emacs users.Īfter pressing M-x R press enter.

The way to get out of this is to quit the current command in the mini-buffer using the shortcut C-g. If Emacs is stuck and does not respond look at the mini-buffer first, chances are that you inadvertently used some keyboard shortcut to invoke some Emacs command and now it is waiting for your further input. Every shortcut you press is reflected in this mini-buffer. It is the line at the bottom of the window, which contains the line M-x R. One of the defining features of Emacs is its mini-buffer. You should see something similar with other Emacs distributions.

This how Emacs window looks on Mac OS X using Aquamacs Emacs distribution. To start ESS simply start Emacs and press M-x R. But do not worry, the rewards as with R are great. For Windows, I recommend to point Emacs home directory to the directory where all your source resides, this might involve setting some environmental variables for older versions of Windows.Īs you see the initial investment might seem a bit daunting. For Unix type OS (Linux and Mac OS X) this would be your home directory. We suggest using a separate directory for every project, which resides in a parent directory called for example R, which resides in some directory which is easily accessible. The same rules for organizing code should apply. Working with ESS does not differ from working with R.

For Mac OS X, you can use Aquamacs which supports native shortcuts, among other things.

So invest some time in finding out how to do that efficiently. Since Emacs is very sophisticated, finding out how to simply select text and copy might be a challenge. This will be oriented towards users which have minimal experience with Emacs. First, you will need to learn how to perform basic text operations with Emacs. In the following we will describe one possible way of working with ESS. and you won’t have to open an external R console: everything can be done from within Emacs.Ī nice overview of Emacs capabilities has been given by Dirk Eddelbuettel in his answer to the

Now, you will have access to a lot of R-specific functionalities, including syntax highlighting, auto-indentation of code, line-by-line evaluation, etc. There is more to see with the ESS package. It offers a lot of functionalities and will be suitable for the basic copy/paste activity described above. Emacs is a powerful tool (it’s difficult to say it is just an editor) for programmers and users dealing with text file.

Well, install Emacs if it is not already present on your system, and you’re almost done. So, basically, let’s keep it simple and just use an R-aware text editor. However, R is a statistical language and offers a lot more interactivity, though that might hardly be reduced in a series of click and go actions. That may appear a crude way of working with R, especially for those used to statistical packages featuring a spreadsheet-view of the data and a lot of menus and buttons with which the user can interact. This allows to build efficient R code in an incremental fashion. A good editor might even provide syntax highlighting, parenthesis matching, and a way to send a selected portion of code to R directly. A simple yet efficient way to work with R consists in writing R code with your favorite text editor and sending it to the R console.
