Hi All, Is it possible for system.time() to measure the time it takes for a machine to evaluate more than one R expression?
For example, # This I can do: > system.time(x <- rnorm(100000)) [1] 0.07 0.00 0.13 0.00 0.00 # But this I can't: > system.time(x <- rnorm(100000); new <- sample(x, 100000, replace=T)) Error: syntax error # Nor this: > system.time(x <- rnorm(100000) + new <- sample(x, 100000, replace=T) Error: syntax error I'm trying to compare two fairly large code chunks, so executing system.time() individually for each expression and then summing the results seems suboptimal. Have I missed something simple?
