I like Violin plots in R

I like the Violin plot and here’s one compared to a box plot.  It’s a box plot and a Kernel Density plot together.

The R code to produce it is below.

Oracle XE – Uninstall causes Windows Event Log to Stop

I’ve seen this a couple of times now.  After uninstalling Oracle XE the Windows 7 eventlog service stops (Windows Event Log).  Before anyone blames Oracle alone on this I’ve found similar posts with the same issue on installing/deinstalling Sql Server.

Hope this helps.

The main issue I’ve found was correct by changing the permissions on the folder and items in the folder %WINDIR%\system32\winevt\Logs.
