This seems like a recipe for garbage results to me, but there may be I
something you can set the error option
to. See ?options.

Hi R-help,

I've looked at google, the Rscript documentation and the Rscript --help
output and haven't found much on this.  So, here's my question:

I have a rather long script that runs on various input datasets.  It is
quite convenient to run the script from the Terminal command line with
"Rscript scriptname.R"

However, some datasets will cause errors. These are non-essential
errors --
just some datasets don't have certain columns so certain parts of the
overall analysis don't produce figures etc.  Yes, I could go through
the
whole script and insert try() statements, etc.  But I'm lazy.

So, is there a way to run Rscript or something similar, and just have
it
ignore all errors (i.e., keep running through the script)?  I.e., just
like
what happens if you just copy-paste the whole script into the R window
--
errors happen and are noted but the rest of the script keeps running.

Thanks very much for any help!!

Cheers!
Nick

This is a really, really simple "life-hack" of mine after failed past
attemps to solve this
? issue?
:
Option
?1?
: Write an if(foreseen error){empty} so if _that_ happens, the code just
ignores it.
??Option 2: Try to run same code for the different initial values in
different windows, so if one stops, another one keeps running.?
I am interested in finding a real solution
? (like the one proposed above by Mr. Newmiller)?
, so I am looking forward to some more expert's say.

Best regards.
