Thanks Duncan. I think you found it. I have an object called s within my function. I wanted to check it, so I hit "s". This did not bring the object but instead it change behaviour of debug function. I did not find this in help pages nor in R exts or R intro manual. Maybe it would be worth considering to add something about it to debug help page.

As it is not the first time, users did not "find" this, I have made the links a bit more visible (for future R versions), now. I'd use '(s)' instead of 's' [and more often and importantly, I have a variable 'n' somewhere and need to use '(n)' very regularly. For smallish situations, btw, the use of ls.str() comes very handy. It has to be noted that unfortunately, the difference between 'n' and 's' and 'c' has been a bit "blurred" for byte compiled functions, and as the default JIT level is high, I had occasionallz wanted an easy way to revert the byte compilation before debugging.... or another way to get rid of this drawback..
