This is something peculiar about the environment on one particular linux
box, because it doesn't happen on other computers. Whenever I invoke
browser() inside a function, it automatically enters debugging mode,
with line-by-line execution of code:
> dum <- function() { browser(); x <- rnorm(10); print(x) }
> dum()
Called from: dum()
Browse[1]>
debug at #1: x <- rnorm(10)
Browse[2]>
debug at #1: print(x)
Browse[2]>
[1] -0.41466890 0.02276493 1.01332894 -2.72784447 0.73471652 0.41360718
[7] 1.67942142 -1.47384724 1.12129541 -1.13447881
> isdebugged(dum)
[1] FALSE
Thanks in advance for any tips on how to revert to the normal browser()
behavior.

What do you see elsewhere? Duncan Murdoch
It appears to be a difference between versions 2.* and 3.* in the way
that a newline ('enter') is handled at the browser prompt. Formerly, it
would continue execution of the function; now it kicks you into
debugging mode. To get the old behavior, you need to enter 'c' at the
browser prompt.
