[R] Has anyone created diagrammatic representations of Access/ODBC databases using R?

I have been on a fair old learning curve handling a fairly complex Access database with my beloved, if sometimes tantaslising, R. I've been using RODBC to do this and, despite the database not being all that well designed, the power of R and RODBC has been fantastic (of course). Huge thanks to R

[R] No speed up using the parallel package and ncpus > 1 with boot() on linux machines

I think I am failing to understand how boot() uses the parallel package on linux machines, using R 3.2.2 on three different machines with 2, 4 and 8 cores all results in a slow down if I use "multicore" and "ncpus". Here's the code that creates a very simple reproducible example: bootReps <- 5
