;;; Commentary:
|
|
;; Ess-tracebug is a package for interactive debugging of R code from
|
|
;; ESS and provides such features as:
|
|
;; - visual debugging
|
|
;; - browser, recover and conditional breakpoints
|
|
;; - watch window and loggers
|
|
;; - on the fly debug/undebug of R functions and methods
|
|
;; - highlighting of error source references and easy error navigation
|
|
;; - interactive traceback.
|
|
;;
|
|
;; For a complete description please see the documentation in the ESS
|
|
;; manual.
