finding a function or a line while debugging?

Say for instance I am running a code using quantstrat package and on a particular line I get the error saying x is missing in is.array(x). I want to figure out where is.array is in all the codes that my code refers to? How do I do this? Is there like a grep or search function that can say tell me that 'here is the function inside which is.array(X) is being called' etc? out<-try(applyStrategy(strategy=stratSMA5D , portfolios=portfolio.st)) Error in is.array(x) : 'x' is missing
