Profiling R6 classes is next to impossible as the methods are anonymous #71

Check out profvis for a tool that can be used to profile R6 methods. Methods will still show up as <Anonymous>, but you should be able to identify them from other information provided by profvis. In order for the methods to not show as <Anonymous>, you could save them in a temporary variable and then invoke that (as in foo <- self$foo; foo()). If you don't want to do that kind of workaround, the R profiler itself would have to provide more information. This may happen in the future, but it's not something that can be addressed from the R6 package.

If you're using a recent version of R-devel (since this commit), it will output obj$fn instead of <Anonymous> in the profiling data. This should be in the next release of R (3.3.0?).

Great thanks, I'll check this out.
