Hello, After experiencing some difficulties with large arrays, I was surprised to see the apparent need for class to gc() after creating fairly large arrays. For example, calling
a<-array(2, dim=c(10,10,10,10,10,100)) makes the memory usage of a fresh session of R jump from 13.8 Mb to 166.4 Mb. A call to gc() brought it down to 90.8 Mb, > gc() used (Mb) gc trigger (Mb) max used (Mb) Ncells 132619 3.6 350000 9.4 350000 9.4 Vcells 10086440 77.0 21335887 162.8 20086792 153.3 as expected by > object.size(a) [1] 80000136 Do I need to call gc() after creating every large array, or can I setup the system to do this more often or efficiently? Thanks very much, Iago $platform [1] "i686-pc-linux-gnu" $version.string [1] "R version 2.6.1 (2007-11-26)" ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
