[R] un run run...

[ONKELINX, Thierry]

Here is an example in pseudo code.

Instead of 

Object <- function that can generate error
Other things to do

Do something like

Object <- try(function that can generate error)
if(class(Object) == "try-error"){
	things to do when an error occures
} else {
	other things to do
}

HTH,

Thierry

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to
say what the experiment died of.

The plural of anecdote is not data.

The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of
data.

Hi All,

I am running an Rscript with a bunch of algorithms that are UNSTABLE
under some parameter settings.

At a certain point one of them sends error massage and my whole run
STOPS!

What I would like is to save the error massage in some file or variable
and carry on to the next command line without stopping this run...

Any help or ideas would be welcome, please, with a concrete example (not
just - "have you thought of using 'tryCatch' etc.).

Thanks all!
Nir
