Fitting
fit<-lm(y~x)
ore.save(fit, name='regression_fit', overwrite=TRUE)
ore.save()
will store the R object 'fit' in the datastore
with the name 'regression_fit'. overwrite is a logical value specifying whether to
overwrite the datastore if it already exists; the default is FALSE.
The overwrite flag is set to true to make sure that ore.save() does not fail. This is one way of doing it; otherwise, the user's script should check for the existence of the datastore object.
