Hi,
f1 <- function(){
browser()
print("aaa")
}
f2 <- function(){
a <- 12
eval(envir = parent.frame(),
bquote({
b <- .(a)
}))
}
Now do,
f1()
and enter n RET and then {1+2}:
Browse[2]> {1 + 2}
debug at #1: 1 + 2
Browse[3]>
{} is now being debugged. This was never bothering me till I got into
unexpected behavior with functions that evaluate in the current
environment.
For example calling f2() starts debugging b <- 12:
Browse[2]> f2()
debug: b <- 12
Browse[4]>
Is there some sort of dont-debug-me flag that I can set in f2 to avoid
this behavior?
Thanks,
Vitalie
