Could you be a little more explicit of what the error message is. On my Windows system 32-bit, I get the following:
> Rprof() > z <- 1 > system.time(for (i in 1:1e8) z <- z + 1/i) Error: cannot allocate vector of size 381.5 Mb Which is probably due to trying to allocate 1e8 elements of integers (400MB). Could you have a similar problem? Now you could restructure your code to not allocate the large vector by: Rprof() z <- 1 i <- 0 system.time(while((i <- i + 1) < 1e8) z <- z + 1/i) z Rprof(NULL) On Mon, Feb 4, 2013 at 7:48 AM, c97sr <s...@stevenriley.net> wrote: > Am also having trouble with Rprof. > > I am using on R 2.15.2 on the Mac (Platform: x86_64-apple-darwin9.8.0/x86_64 > (64-bit)). > > The example above without profiling takes around a minute to run: > >> z = 1 >> for (i in 1:1e8) z = z+1/i >> z > [1] 19.9979 > > With profiling: > >> Rprof() >> z = 1 >> for (i in 1:1e8) z = z+1/i > > [INFO] Feb 4, 2013 12:45:20 PM - R stopped. > > Crashes within a second or so. > > This is consistent with the problem I'm having in my own code in which there > is a reasonable amount of memory used (but not a massive amount). > > Any help much appreciated.
