[Rd] Problem building R with Intel MKL v10 BLAS

different than in the R-admin manual because of changes in the Intel MKL for version 10. These libraries, in this order, were taken from the Intel MKL for Linux User's Guide, chapter 5. So, still no luck linking to the optimized BLAS. I'd appreciate any suggestions. Thanks, Michael

[Rd] R scripts slowing down after repeated called to compiled code

e day thinking I have a memory leak, but that no longer appears to be the case. I tried using Rprof(), but that only gives me the aggregated relative time spent in each function (more than 80% of the time, it's in the .Call). So I'm stuck. Can anyone help? Thanks, Michael -- M
