G'day, All.
I've recently started writing up my dissertation and need to consider how to
store the research results. I'd like to use the binary compressed save() format
as it is considerably smaller than the raw data. However, will a future R be
able to read it into the indefinite future or would I be better off just
compressing the text data files? The doc says:
All R platforms use the XDR (bigendian) representation of C ints
and doubles in binary save-d files, and these are portable across
all R platforms. (ASCII saves used to be useful for moving data
between platforms but are now mainly of historical interest.)
The format is well known and platform agnostic, both excellent properties, but
will I be able to read the data into a more modern version of R into the
foreseeable future?
Yes, that's the intention. It can sometimes go wrong: e.g. if you have
an S4 object you'll likely need to have a compatible version of the
package installed when you load the object again. But for simple data
types there will be no problem.
