Hi, I was wondering if there is a function or package for R that can be used for "line-by-line" profiling, and yields an output similar to Matlab's profiler? For those of you that are not familiar with the Matlab profiler, it shows you how much time each line in the code took to run. Moreover, if the function/s included in that line are not "built-in", you can click on them and see the time it took to run each line within that function. Is there anything similar in R? I've tried Rprof and the profr package, but they have not been very helpful. Thank you very much in advance. [[alternative HTML version deleted]]
