I have a simple question that irritatingly I haven't been able to figure out on my own. It seems that some functions from the "Pspline" package are successfully installed while others are not. The code with which I'm working is more complicated, but the following highlights my problem. If I run the following code
> tt <- seq (0,1,length=20) > xt <- tt^3 > fit <- smooth.Pspline (tt, xt, norder=3,spar=0.0001, method=1) > pred<- predict.smooth.Pspline (fit, tt, nderiv=0) I get this error: "Error: could not find function "predict.smooth.Pspline" " So it seems like "smooth.Pspline" is loading but "predict.smooth.Pspline" isn't. Any ideas about why this might be the case? -Zoe Richards [[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.
