Dear All, I'm a real beginner in R(a windows version) and I'm trying to install the principal curves packages(from http://cran.r-project.org/src/contrib/PACKAGES.html#princurve ) by using the following comand: -------------------------------------------------------------------------------------------------------- shell("Rcmd INSTALL d:/bin/cran/princurve"). ------------------------------------------------------------------------- but I got lost with the messag...

Hey all, I can't seem to get the princurve package to produce correct results, even in the simplest cases. For example, if you just generate a 1 period noiseless sine wave, and ask for the principal curve and plot, the returned curve is clearly wrong (doesn't follow the sine wave). Here's my code: library(princurve) x <- runif...

...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...

Hi, I'm wondering which function would allow fitting this type of data: tmp=rnorm(2000) X.1 = 5+tmp Y.1 = 5+ (5*tmp+rnorm(2000)) tmp=rnorm(100) X.2 = 9+tmp Y.2 = 40+ (1.5*tmp+rnorm(100)) X.3 = 7+ 0.5*runif(500) Y.3 = 15+20*runif(500) X = c(X.1,X.2,X.3) Y = c(Y.1,Y.2,Y.3) plot(X,Y) The problem with loess is that distances for the "goodness of

Sorry, for disturbing the list again. > Also I got one suggestion of using ORDPACK at http://www.netlib.org/. It's ODRPACK at http://www.netlib.org/, not ORDPACK.

A student of mine wants to use R to do some nonmetric multidimensional scaling. According to the R FAQ, there's a package called pcurve that computes multidimensional scaling solutions, but I was not able to locate it the contrib page (I am a Windows user with R version 1.4.1). Can anyone tell me whether it is possible to do nonmetric multidimensional scaling with R, and if so, how? John
