Translates an oldlogspline object in an
logspline object. This routine is mostly used in logspline,
as it allows the routine to use oldlogspline for some situations
where logspline crashes. The other use is when you have censored data,
and thus have to use oldlogspline to fit, but wish to use the
auxiliary routines from logspline.
oldlogspline.to.logspline(obj, data)object of the class logspline. The call component
of the new object is not useful. The delete component of the old
object is ignored.
object of class logspline
the original data. Used to compute the range component of the
new object. if data is not available, the 1/(n+1) and n/(n+1)
quantiles of the fitted distribution are used for range.
