[R] Hard Stop?

[William Dunlap]

q()?

E.g.,
  > f <- function(x) { switch(sign(x)+2, q(), stop("Oops"), NULL) ; sqrt(x) }
  > tryCatch(f(2), error=function(e)"error")
  [1] 1.414214
  > tryCatch(f(0), error=function(e)"error")
  [1] "error"
  > tryCatch(f(-2), error=function(e)"error")
  Save workspace image? [y/n/c]: c
  > for(i in 1:3)tryCatch(f(-2), error=function(e)"error")
  Save workspace image? [y/n/c]: c
