Dear all
I have a question about debug function. I did not use it for long time but my
vague memory tell me, that when I used debug(myfunction) in past, only
myfunction was debugged and browser ignored any embedded function.
example (simple)
fff <- function(x) mean(x, na.rm=T)
when I issue
debug(fff)
fff(1:10)
debugging in: fff(1:10)
debug at #1: mean(x, na.rm = T)
Browse[2]>
debugging in: mean(x, na.rm = T)
debug: UseMethod("mean")
Browse[3]>
debugging in: mean.default(x, na.rm = T)
...
it starts debugging mean function. I understand that it is indicated by
Browse[n] but it could be quite messy if I have many embedded functions and
difficult to follow.
Can I persuade debug function not to bother with embedded functions (e.g. mean,
median, mad, ...) and debug only my top level code?
There are several commands available. Type "help" to see them:
n next
s step into
f finish
c or cont continue
Q quit
where show stack
help show help
<expr> evaluate expression
You want "n", and are getting "s". I believe if you hit Enter without
choosing one, it will do the same as the previous time, so you've
probably used "s" sometime in the past.
