R equivalent to MATLAB's "stop if error"

Question

I'm attempting to debug an R program, and I'm sorely missing the stop if error capability of matlab. I've gone through the R-debug-tools.pdf (mirror) documentation, but it didn't list anything like this. Is there any way to instruct R that, when any error at all is encountered - even one I didn't anticipate and plan for with a custom trace function - it should stop execution and throw me into browser() mode?

Answer 1

I believe you want options(error=recover)
