![]() 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. If I should be attaching some kind of log or other info that I do not know about, please let me know.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. However, this appears to me to be an ssh problem, as a wild guess.Īny suggestions? Does the failure to connect have anything to do with ccl/swank/slime, or do I have some ssh pondering to do? For example, I have no idea why we need to "fool" emacs into thinking it is talking to 127.0.0.1. I know *nothing* about ssh, or for that matter networking generally. Lisp connection closed unexpectedly: connection broken by remote peer.Īnd in the ssh terminal session on the Mac to Ubuntu I see this:Ĭhannel 3: open failed: connect failed: Connection refused However, when I then do M-x slime-connect in aquamacs and connect to 127.0.0.1 port 4005 I get this message in aquamacs: It looks just like a regular ssh login I don't know if that is what is expected. I see an ubuntu prompt in my Mac terminal. It does open up a "visible" ssh session, i.e. The result of keying in the above is that I get a prompt for a password, and an apparently successful connection to the Ubuntu machine. In a terminal on my Mac I do the incantation suggested in the slime manual p.26, i.e. I can log in from the Mac to Ubuntu over ssh with no problems. That is, I can start ccl in a terminal, fire up a swank server, and then connect from emacs/aquamacs by means of M-x slime-connect to the server on the same machine. ![]() I followed the instructions in the slime manual to connect locally on both machines. On Ubuntu 10.10 I am using ccl 1.7 32-bit, with yesterday's FAIRLY-STABLE slime/swank. This is described on the aquamacs site as. On the Mac I am using ccl 1.6 64-bit, with the slime/swank provided by aquamacs as of yesterday. I am attempting to connect from aquamacs emacs + slime on my Mac to a remote lisp on Ubuntu 10.10.
