There's a "package development mode" in ESS: https://github.com/emacs-ess/ESS/blob/master/lisp/ess-r-package.el I think that ESS automatically detects that you're inside a package directory and adjusts its behaviour. This could be related to "namespaced evaluation" <https://ess.r-project.org/Manual/ess.html#Namespaced-Evaluation> ("evaluate code in the context of the package being developed", sounds useful), but I'm not sure about that. > 3. Why is that temporary file /tmp/foo.R!djSwRn created? It's probably some part of ESS's mechanism of running R code. I don't see where the temporary file name is constructed (maybe a built-in Emacs function?), but it probably comes from <https://github.com/emacs-ess/ESS/blob/master/lisp/ess-r-mode.el>. (Look for calls to .ess.source or .ess.ns_source.) > 4. What is that function ss() in the error message referring to? `ss` is a function defined by ESS in order to call R's source() in a way portable between a very wide range of R versions. (A comment in the same file says "Should work on *all* versions of R. Do not use _ in names, nor :: , nor 1L", which includes versions of R considered very old by now.): https://github.com/emacs-ess/ESS/blob/master/etc/ESSR/R/.basic.R#L178 > 5. Could this be a virus? Under Ubuntu? A virus has little reason to be doing this to you. There's much more money to be made from malicious VSCode extensions than Emacs add-on packages. Since you've determined ESS to be causing the difference in the behaviour, perhaps <https://ess.r-project.org/index.php?Section=getting%20help> is the way to go? Unfortunately, I'm not a user of ESS or Emacs, so I'm going off what information I found on the Web, which may be outdated. -- Best regards, Ivan ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
