Question

I’m looking for a way to store running times in a variable in R. In MATLAB one can do something along the lines:

tic;
…
x=toc;

and then the running time is stored in the variable x. I have tried doing the same thing with the tic() toc() function in R coming from the MATLAB-package without success. Furthermore I can’t see how this can be done using the system.time() function of R neither. Any help here is much appreciated.

Use the built-in system.time function:

tm1 <- system.time(
{
  #your code here
})

or, alternatively the benchmark function from rbenchmark package:

tm2 <- benchmark(
{
  #your code here
}, replications=1)
