Hi all,
Could you please help me?
I am having the following weird problem when debugging R programs
using "browser()":
In my function, I've inserted a "browser()" in front of Step 1. My
function has 3 steps and at the end of each step, it will print out
the message "Step i is done"...
However, after I hit<ENTER> when the program stopped before Step 1
and entered into the debugging mode, it not only executed the next
line(i.e. the Step 1), but also all the (many) remaining lines in that
function, as shown below:
Browse[1]>
[1] "Step 1 is done.."
[1] "Step 2 is done.."
[1] "Step 3 is done.."
Then it automatically quited the debugging mode and when I tried to
check the value of "myobj", I've got the following error message:
names(myobj)
Error: object 'myobj' not found
No suitable frames for recover()
----------------------------------------------------
So my question is: why did one key stroke<ENTER> lead it to execute
all the remaining lines in that function and then "returned" from the
function and quited the debugging mode?
See ?browser.
