Dear R friends.
After having some troubles learning how to create a ffdf object, now I find
myself having problems saving it.
this is the data i´d like to save:
str(DATA)
List of 3
$ virtual: 'data.frame': 6 obs. of 7 variables:
.. $ VirtualVmode : chr "double" "short" "integer" "integer" ...

$ row.names: NULL
- attributes: List of 2

.. $ class: chr "ffdf"
the function I used to do this was:
*ffsave(DATA, file='//N7700PRO/Datos/Datos_Servidor_Lucas/DATA')*
this gives me the next error:
*Error in system(cmd, input = filelist, intern = TRUE) : 'zip' not found*
I found that I needed to have some kind of Zip and UnZip tool, this comes
in Rtools, so I installed the Rtools *Rtools215* because I have installed
the R.2.15.1 version.
After installing the tools I keep getting the same problem, do I have to
re-configure something in R? or the tools are suposed to work alone after
installing?
If any can help me with this, I´d really appreciate it.
Lucas.
