| 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The functions traceOn and traceOff have been replaced by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:traceOn:what. The function
or expression tracer is called on entry, and the function
or expression exit on exit.
traceOff:browseAll:
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.
See Programming with Data (John M. Chambers, Springer, 1998) for the equivalent functions.
