Indeed it does! Sorry for the impulsive response!

An interesting thought just came to me when reading this discussion! I
use both R and Latex and have never had the trouble of overlooking
error messages when debugging long Latex code!
Of course this is because when compiling a latex document, a summary
of the compilation process is provided at the end! If any errors
occurred, they will be mentioned in the summary.
Maybe R could provide the same summary as an optional part of the
source() command!?
I think it does, doesn't it? R will stop at the first error and print
it, e.g.
> source('c:/temp/test.R')
Error in parse(file, n = -1, NULL, "?") : syntax error on line 4
If there were only warnings, it will show them at the end:
> source('c:/temp/test.R')
Warning messages:
1: longer object length
is not a multiple of shorter object length in: 1:3 + 1:4
2: longer object length
is not a multiple of shorter object length in: 1:3 + 1:4
Even if you use echo=TRUE, these summaries show up at the end. It's
only if you use cut and paste that you might miss these.
