[R] data smoothing

[stefano.giampiccolo]

Good morning,
I have a time serie of clinical data. I know, from the literature, that it
must have a linear trend, without seasonal oscillations. Can I use LOESS to
have a qualitative confirm? I have only 15 mensurations: how should I choose
the smoothing parameter?
Thanks, best reguards
