Thank you Alexander 2010/5/17 Alexander Shenkin ashen...@ufl.edu You could also put the call to system.time inside the function itself: f = function(x) { system.time({ ... #function's code ret_val = ... }); flush.console(); return ret_val; } i s'pose you'd miss

Re: [R] timing a function

Dear all, Just one last question. There seems to be no problem in writing z = system.time(y - f(x)) or z - system.time(y - f(x)) Then z contains the named vector of the elapsed times, and y the value of the function f(x). Am I right ? Thank you very much, Gustave 2010/5/17 Alexander
