This doesn't tell us much either. What does the variable "incline" represent, and what does the variable "ToC" represent? I could guess your data looks something like : ToC Incline x1 -90 x2 -60 x3 -30 x4 0 x5 30 x6 60 x7 90 x8 -90 ... ...
Or incline could be the number of the sample (going from 1 to 7). No way to know what you did. Please, read the posting guide and take the hints given there into consideration. This said, you very likely just have not enough data to use a thin plate regression spline without limiting k. see ?choose.k and ?null.space.dimension Cheers Joris On Thu, Jun 3, 2010 at 2:49 PM, natalieh <fbs...@leeds.ac.uk> wrote: > > Data? > > The data are measures of energy use (continuous variable) for running on 7 > inclines between -90 and +90 degrees (n=7-21). > -- > View this message in context: > http://r.789695.n4.nabble.com/gam-error-tp2241518p2241608.html > Sent from the R help mailing list archive at Nabble.com. > > ______________________________________________ > R-help@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide > http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. > -- Joris Meys Statistical Consultant Ghent University Faculty of Bioscience Engineering Department of Applied mathematics, biometrics and process control Coupure Links 653 B-9000 Gent tel : +32 9 264 59 87 joris.m...@ugent.be ------------------------------- Disclaimer : http://helpdesk.ugent.be/e-maildisclaimer.php [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
