In the past I used
sink("timings.lis")
hilbert<-function(n) 1/(outer(seq(n),seq(n),"+")-1)
print("hilbert n=500")
print(system.time(eigen(hilbert(500))))
print(system.time(eigen(hilbert(500))))
print(system.time(eigen(hilbert(500))))
print("hilbert n=1000")
print(system.time(eigen(hilbert(1000))))
print(system.time(eigen(hilbert(1000))))
print(system.time(eigen(hilbert(1000))))
print("sort n=6")
print(system.time(sort(rnorm(10^6))))
print(system.time(sort(rnorm(10^6))))
print(system.time(sort(rnorm(10^6))))
print("sort n=7")
print(system.time(sort(rnorm(10^7))))
print(system.time(sort(rnorm(10^7))))
print(system.time(sort(rnorm(10^7))))
sink()
would that do ?
