How can I call/execute an imageJ macro with R? -

-

i've written macro in imagej spits out data frame analyze in r. i'd love able have whole procedure work in r without having first run macro manually in imagej. macro prompts user input , output directories , it's thing. i'm thinking there must function in r allow me specify macro , input , output directories (i recode these variables in macro somehow take these arguments through r script?)

i gather can use system() command , found tantalizing clue somewhere else on web: 

system("./javaapplicationstub  directory file[i] -batch zmacro")

but not sure how implement (my macro utilizes batch processing part unnecessary).

here example run macro file "test.ijm" cl (in osx). wrap command in r (not tested). path macro file should full path, not relative path. 

/applications/imagej/imagej.app/contents/macos/javaapplicationstub -batchpath /tmp/test.ijm

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
