Several comments:
1. Why did you send this request to R-SIG-gR?
This is a SIG (special interest group) on gR (graphical models
in R) and your request does not seem to be related to that!
2. A better place to ask questions like the above is R-help.
But one should read the posting guide before doing so.
http://www.R-project.org/posting-guide.html
3. If you read the posting guide, it will tell you that:
If you have problems with some function, please do give a
reproducible example (including your version of R and OS,
indicate add-on packages you use, etc.).
For your request above, there is nothing much that we could do. After I
had found out that this is about a function in the package princurve (do
note that there is a second CRAN package pcurve for the same task), all
I can say is that
R> library(princurve)
R> example(principal.curve)
R> fit <- principal.curve(x, plot = TRUE,
smooth="periodic.lowess",
iter= 0)
gives some warnings but does not throw an error as you indicated above.
This is on Linux with today's R-devel (2.1.0 to be) with the current
CRAN version of princurve.
