It is quite obvious why you get the error message; check your data: Error in wynik[, i] <- dodawanie(wzorzec, wzorzec1) : number of items to replace is not a multiple of replacement length No suitable frames for recover() > > i [1] 1 > dodawanie(wzorzec, wzorzec1) [1] 3 5 4 2 6 3 > str(wynik) num [1:10, 1:2] 0 0 0 0 0 0 0 0 0 0 ... >
You are trying to put 6 items (return value) into 10 rows of the matrix; you must have a bug in your program.
