Re: [R] browser always enters debug mode

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.

[R] browser always enters debug mode

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(1

Hi, I often work from home, running R on my office computer and displaying interactive graphics on my home computer using X11. This was always more sluggish than sitting at my office computer, obviously, but recently the graphics transfer has become painfully slow -- so slow, that I now dive

[R] ubuntu installation: can't find ldpaths
