[R] Conversion to Binary (base2)

[Carl Witthoft]

It occurs to me that Christos' method could be made more flexible by 
using rle().  That is, before collapsing the digits,  you have something 
like

 >foo
[1] 0 0 0 0 0 0 0 0 0 0 0 1 0 1 1 0 0 1 0

Then rle(foo) will show you where the boring lead-zeros end, and you can 
use that value to set the truncation ---- rather than a fixed [1:17] as 
below.

This was what I was looking for to solve the truncate to 17 digits. 
Thanks a lot.

Now my output looks like this:

0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 ,0
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 ,0.0998004
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 0 ,0.1996008
