A more informative abort message than "aborting ..."

[HenrikBengtsson]

WISH

Use An exceptional error occurred that R could not recover from. The R session is now aborting ... instead of just aborting ..., because from the latter it is not always clear where that messages comes from, i.e. it could have been outputted by something else. Here's an example:

checking tests ... ERROR
Running the tests in ‘tests/devEval.R’ failed.
Last 13 lines of output:
1: .External2(C_X11, d$display, d$width, d$height, d$pointsize, d$gamma, d$colortype, d$maxcubesize, d$bg, d$canvas, d$fonts, NA_integer_, d$xpos, d$ypos, d$title, type, antialias, d$family)
[...]
12: tryCatch({ res <- devEval(type, name = "any", aspectRatio = 2/3, scale = 1.2, { plot(100:1) }) printf("Result: %s (%s)\n\n", sQuote(res), attr(res, "type")) devOff()}, error = function(ex) { printf("Failed: %s\n\n", sQuote(ex$message))})

PR #16749 closed; Martin Maechler updated R's abort message R devel r70288. In interactive mode, we now get:

[...] 
> Possible actions: 
> 1: abort (with core dump, if enabled) 
> 2: normal R exit 
> 3: exit R without saving workspace 
> 4: exit R saving workspace 
> Selection: 1
R is aborting now ...

and in non-interactive mode (including R CMD check) we get:

An irrecoverable exception occurred. R is aborting now ...

From the R CMD check output of the original example, it should now be a bit more clear that it is R that is aborting, e.g.

checking tests ... ERROR
Running the tests in ‘tests/devEval.R’ failed.
