debugging - Could Emacs Speaks Statistics loop through a R for loop like a real debugger? -

-

i happy user of ess coding , debugging r code. have found elusive bug inside several loops , ifs structures.

is there way of having ess selectively travel if/else structures or loop values in loop?.

does r or ess have debugger mode can skip else clauses, loop values , step into, step through, return etc?

[update]

thanks @jubba link other question debugging tools r-language. @ end real question. other thread give links kind of things wanted know way of doing debugging in current r.

there has been more general question debugging in r on stackoverflow :

debugging tools r language

one answer davor cubranic points ess-tracebug is, according website, "an emacs package interactive debugging , error tracing in ess". i've never used myself, may useful :

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
