Hi Fellows from R-Help List! My questions are basic since i an new with R. I am very acquainted with Matlab & Gauss (the compentence, I guess). Anyhow, (1) I am trying to get R execute comands made or built as text, so that one can feed a particular option with many variations coming from a text file. Is this possible with the free version? For instance, there exists the eval comand in Matlab, which executes the matlab comand in the text argument incoming thru eval. (2) Is there any way to avoid the automatic stop of a redundant NL estimation, like for instance, the one behind arima()? Usually, when the NL problem has spikes or the like, even the global optimizer procedures stop. If many models are supposed to be estimated and you just want to bypass those badly-behaved models (and store the many statistic values just as NAs), such a stop makes you correct the loop indexes and re-run the program. How to avoid it? Best Carlos

I think what you need to do first is to read the manuals. "An Introduction to R" would be a good start. There is no "free version" vs "commercial version". R is open-sourced and you don't have to pay for it -- of course, "donations" are welcome by the R Foundation ;D.
