Hello to everyone,
I'm a newbie with ff package and I´m starting to use it. I´ve been reading
the ff.pdf guide and another documents and questions , but I´m really
confused about some procedures I can´t see how to do. I´d want to know if
it´s possible (and how) to "save" a ffdf file(s) and open it in another
session, via saving it in an permanet location.
Let´s supose we´re reading from a text file to a ffdf object, with
read.table.ffdf and we want to save the files and information in a permanent
path and file. First of all I read about GetOption("fftempdir") but I don´t
know how to change this parameter. I read also about the pattern option, and
I asume that this option changes the prefix of the files created phisically
under the ffdf object. Isn´t it? Can I use this parameter to create a
permanent location (via putting the entire path) for the files? Can I use
this option after reading the file as ffdf , applying the pattern to the
ffdf object I created before?
The next and related quetion is, if I can save the files in a permanent
location , how can I load them? Can I use the generic load of an image of
the R session?
Thanks in advance for reading this question and please apologize if my
english is not very accurate and/or the question is too simple.
Regards
Daniel.
