[ESS] Emacs can find R-devel and R-newest, but not R-4.0.x
Hi, I used to be able to start a specific R version with M-x R-... but it doesn't work anymore. On M-x R- I see: R-devel R-initialize-on-start R-mode R-newest R-transcript-mode ... but no R-4.0.x. I have R-4.0.0, R-4.0.2, R-4.0.3 and R-devel installed and M-x R-devel and M-x R-newest correctly find and start R-devel and R-4.0.3, respectively. The other two R versions are set up exactly in the same way, which is why it's so confusing that they are not found. Also, in an Emacs shell (M-x shell), R-4.0. completes to all R versions and I can also start every single one of them. Any ideas what to try? This is on macOS 10.15.7 with GNU Emacs 26.3 and ESS version 18.10.2 [Released git: d4cd65da6dbf].

[ESS] error in process sentinel: Not enough arguments for format string
Hi, As I reported on https://github.com/emacs-ess/ESS/issues/883 (last post), I'm (still) affected by the randomly appearing error "error in process sentinel: Not enough arguments for format string" and related 'freezing' of Emacs (which is especially popular when teaching in front of 300 students :-) ). My workaround so far was to use M-x flymake-mode to disable flymake which solved the problem. Before disabling flymake mode completely (not sure if (setq flymake-start-on-flymake-mode nil) would be correct...), I thought I'll ask to a) express that the problem still exists and b) perhaps learn how to properly tell ESS to avoid flymake mode or to deal with the problem otherwise. After browsing a bit, I found ess-r-flymake on https://emacs.stackexchange.com/questions/46556/error-in-process-sentinel-whenever-using-in-an-ess-r-buffer?noredirect=1=1 but I'm not sure if that's the write place for modifications for disabling flymake mode. I'm using ESS 18.10.2 [Released git: d4cd65da6dbf] and GNU Emacs 26.3 on macOS (the problem appeared at least in 10.14 and 10.5). I don't have a reproducible example. I did get the feeling though that chances of triggering the error are slightly higher if I'm "fast", for example, quickly switching to an R buffer and trying to make modifications or quickly navigating through many lines of source code and then modifying a line. It appears maybe 2 to 3 times a day when I'm programming. Thanks & cheers, Marius __ ESS-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/ess-help
[ESS] in 18.10.3: Roxygen header is put at the wrong place if point is at the beginning of the line
Hi, I realized that in the current snapshot version of ESS (18.10.3), C-c C-o C-o (for Roxygen function headers) does not work as expected anymore (on macOS 10.14.5) in the following case (and others): fun1 <- function(x) x fun2 <- function(x) x If the point is right before the "f" (so column 0) of "fun2", then C-c C-o C-o puts the Roxygen header above fun1, not fun2. If the point is anywhere else on that line, the header is put in the right place, so right above fun2. I hope you can reproduce this (I already switched back to the stable 18.10.2 for that reason). Thanks & cheers, Marius __ ESS-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/ess-help
[ESS] Assignment operator "<-" not bound to "_" anymore (or any other default it seems).
Hi, In 18.10.3snapshot (GNU Emacs 26.1, macOS 10.14.4) "_" is not the assignment operator "<-" anymore (it still was in 18.10.2). This step, especially the fact that there is no new default to obtain "<-" (or is there?) might scare away users... I'm also posting this so that others can find it as it took me quite some time to figure out that this was somewhat announced: search for "<-" on http://ess.r-project.org/Manual/readme.html -- referring to version 19.04 (unreleased; why so many versions ahead?). Is there a new recommended way to get "<-"? I now use... (define-key ess-r-mode-map (kbd "M--") #'ess-insert-assign) (define-key inferior-ess-r-mode-map (kbd "M--") #'ess-insert-assign) ... to bind M-- to "<-", as RStudio uses. This makes it easier to switch to RStudio when teaching from that. Don't get me wrong, I'm a die-hard Emacs + ESS user since about 2010 when Martin Maechler introduced ESS to me, but in our undergrad courses with class sizes of up to 1000 students, we are kind of required to teach from RStudio as this is what students nowadays use. Not having a default for "<-" seems weird to me and not everyone likes to make adjustments to .emacs just to get basic functionality (... and thus probably switches to RStudio...).

Re: [ESS] Indent for R's 'switch'
Hi Alex,
thanks for your quick reply. You are right, I used "(setq
ess-default-style 'C++)", so it's a problem of the C++ style.
Thanks for pointing this out.
I can confirm that the problem does not exist in the default style
(although all cases are indented then, which is a bit of a waste of
space since often one has constructions like "my_variable_value <-
switch(...)" and so everything is indented quite a bit; would still
find it elegant to have the cases aligned with 'switch')
Cheers,
Marius

[ESS] Indent for R's 'switch'
Hi,
ESS (version 16.10-1 but also earlier) gives the following indentation
for switch statements in r:
f <- function(method = c("foo", "bar"))
{
switch(match.arg(method),
"foo" = { # (*)
cat("Will use 'method' = \"foo\".\n")
},
"bar" = {
cat("Will use 'method' = \"bar\".\n")
},
stop("Wrong 'method'"))
}
Line (*) is not ideal. Looking over the various cases (in longer
switch statements) along column 4 (containing the "s" of "switch()"),
one can easily overlook the case "foo". The following would be great
to have:
f <- function(method = c("foo", "bar"))
{
switch(match.arg(method),
"foo" = {
cat("Will use 'method' = \"foo\".\n")
},
"bar" = {
cat("Will use 'method' = \"bar\".\n")
},
stop("Wrong 'method'"))
}
Is that possible?
Cheers,
Marius
PS: There is a slight chance I already asked for this long time ago...
not sure anymore, though. Would be good to have.

[ESS] Strange behaviour of ess-eval-buffer-from-beg-to-here?
Hi, Here is some R code, that, when put in an R script (.R), shows some strange behaviour (see sessionInfo() etc. below) under ess-version: 16.10-1. (foo <- matrix(rnorm(100), ncol = 5)) L <- matrix(c(2, 0, 0, 6, 1, 0, -8, 5, 3), ncol = 3, byrow = TRUE) Sigma <- L %*% t(L) P <- cov2cor(Sigma) d <- ncol(P) n <- 1e4 set.seed(271) Z <- matrix(rnorm(n * d), ncol = d) X <- t(L %*% t(Z)) (T <- cor(X, method = "kendall")) If I put the curser in line 2 and execute C-c (ess-eval-buffer-from-beg-to-here), the matrix 'foo' is printed. However, if I put the cursor in the line after the last one and execute C-c , I still see the matrix 'foo' but the correlation matrix 'T' is not printed. (If I step through the code line-by-line, T is of course printed). Is this a bug? I could replicate a similar behaviour (T not printed) as above with C-c C-c (ess-eval-region-or-function-or-paragraph-and-step). Needless to say, this is frustrating if you want to show several outputs/variables at once in a script (for example, when teaching). I can't remember this ever happening before. Any ideas?
