Hi, everyone. I am using a fair amount of closures in my code. Problem i am
experiencing is i cannot figure out how to mtrace functions defined within a
function. There must be some way to name such function for mtrace to see it
and let me step into it. For example, say i have code
mymodel<-function(){
data<-numeric(0)
build<-function(){
data<<-1
}
m<-list()
m$build<-build
m
}
How do I mtrace build function defined inside mymodel function so that i can
step into build?
I don't use mtrace, but you can use setBreakpoint() to set a breakpoint
by line number, and presumably you could set the action to whatever will
trigger mtrace. It will modify the source of mymodel so that every time
it creates a new build(), it creates it with a breakpoint within.
See ?setBreakpoint and ?trace.
