I can confirm this. Last prompt is not detected for some reason.

[ESS] Strange behaviour of ess-eval-buffer-from-beg-to-here?

[Marius Hofert]

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?

I have ess-version: 16.10-1 [git:
58c130a1bc13c8933bde229424d628ec2b6a6a97] (loaded from
/usr/local/ESS/)

sessionInfo() is:
