| Session {methods} | R Documentation |
The functions traceOn and traceOff have been replaced by
extended versions of the functions trace and
untrace, and should not be used.
sessionData() traceOn(what, tracer=browseAll, exit=NULL) traceOff(what) browseAll()
sessionData:return the index of the session data in the search list, attaching it if it is not attached.
traceOn:initialize tracing on calls to function what. The function
or expression tracer is called on entry, and the function
or expression exit on exit.
traceOff:turn off tracing of this function.
browseAll:browse the current stack of function calls.
Uses the function debugger to set up browser calls on the
frames. On exit from that function, computation continues after
the call to browseAll. Computations done in the frames
will have no effect.
