Does Ubuntu shines through the Windows

I tried all possibilities to get Linux/Ubuntu running on a Windows machine. Running in a virtual machine: too slow; using Cygwin, well, not really Ubuntu, still in Windows. Dual booting, yes interesting possibility but you have to reboot if you want to switch.

Since the latest update on Windows10 there is a new solution. Windows creates the possibility to install a Linux layer.  That is: you have a terminal running bash. Here is the howto: .
Ah you want of course the GUI: Unity for example of Ubuntu. Well you can try, and for me it works. Here is the recipe:
It is not perfect, and sometimes the system crashes. But you can have Ubuntu running together with Windows 10. Now that Microsoft has installed workspaces as well. I run windows in the first and Ubuntu in the second. Finally, the Linux sun shines through the windows.

Integrating Google Charts with R

Making charts and graphs in Excel is not a real pleasure; Google sheets works much better esp if you to publish the graphs and charts on line. Here is an example using Worldbank data. However for data analysis R is my first choice. Now I can integrate R with Google charts, using googleVis in R. Here is the handout.
R-Bloggers published the following example for Worldbank data.
Making moving charts is now so easy. Here is my example based on Worldbank data; showing relationship between GDP per cap and Internet access per 100 from 2001 to 2014 for sub sahara african countries.
Data look as follows:
'data.frame': 154 obs. of  4 variables:
 $ country  : Factor w/ 11 levels "Botswana","Ghana",..: 1 1 1 1 1 1 1 1 1 1 ...
 $ year     : int  2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 ...
 $ gdppercap: num  3115 3044 4149 4879 5328 ...
 $ inetperc : num  3.43 3.39 3.35 3.3 3.26 ...
