Hi, I spotted an inconsistency between the output of funfits under R, more specifically "nnreg", and the one obtained under S-plus. Notice the difference in the "Root MSE", "GVC" and "GVC cost=2". As a check mark, I am also including the data summaries, confirming that I was in fact using the same data set. Here's...

Hello, Does anybody know if there is somewhere in R a function to calculate the Lyapunov exponent in a time series?

Dear all, Has anyone worked on coding for calculating Lyapunov Exponent for a time series data? or any package is available for computing Lyapunov? Please advice and many thanks in advance. Catherine X Wang

Hi All: I am interested in tools available in R that will enable me to run analysis of case crossover studies. I searched the web (http://www.google.com), and found that a tool called "funfit" was available for Splus. Searching the R archives, I also found mention of a "funfit" library. However, when I searched in CRAN, I could not find it. Is "funfit" now part of another package? Or, what other tools are available in R for specifically doing case crossover st...

...with box, and then superpose a second surface (without box and axes) on the top plane of the box defined by the first graph. I don't know if it is clear :-( Is it possible to draw such a second surface in an existing persp plot in R? Another (related) question: once upon a time, it was a 'funfits' library in CRAN. I don't find it on CRAN any more. Is it defunct? I installed an old version 2.0.3 of this library. In the help files, there is a mention about functions like persp.text, persp.points, persp.lines to add features in an existing persp plot... but I don't find them. Do t...

Hello, I have a couple of suggestions that will help persons with machines/OSs that use extensions other than ".so" for shared libs: 1) Use the variable SHLIBEXT (defined in Makeconf), DONT use "so" or "sl". 2) Use the method in "modreg" to load the dynamic lib: .First.lib <- function(lib, pkg) library.dynam("modreg", pkg, lib) DO NOT USE

R-users -- I would be interested in tools in R to fit the following gam model: logit(p) = a + f(x1) + f(x2) + f(x1,x2), where f(x1,x2) defines a surface. I have looked into the mgcv library, but it seems only to fit models of the form: logit(p) = a + f(x1) + f(x2) Any ideas?

[original bounced; re-submitted by list maintainer, MM] I have downloaded the package modreg for R but when i doing "R INSTALL modreg" I get_ errors. With the packages akima, funfits, acepack,KernSmooth and othes i have the same problem. Why?? I need R for working with calibration curves, and i dont know what is the best package for it. I need some packages for fitting nonlinear models. I would like install thes fuctions: rreg(); lmsfit(); l1fit(); and loess. How i can down...

Hi Does someone knows if there's a function/package that can make thin plate splines ? I've looked in mgcv and splines but I haven't found anything.

...0,dim=c(dim(a),dim(b)[2]) for (i in 1:dim(a)[1]) { bb[i,,] <= outrer(a[i,],b[i,]) } bb } Am I missing something? . The help files for 'apply' in R and is S+ are exaclty the same, but the implementations obviously are different. . . Another, tring again to port FUNFITS i get a lot of errors for missing i-o something, I deleted all the 'write(*,*)' from the fortran sources but there remain some 'write(2,*)...' writings to temporary files which the compiler library does not like. I am using MINGW32 1.02 Is there a way to bypass this error and a...

...p at stat.math.ethz.ch Subject: [R] multidimensional function fitting Hello, I have been looking around for how to perform a multidimensional, arbitrary function fit (in any case non-linear; more below), but haven't found anything yet on how to accomplish this. I found some references to the funfits package (that apparently is now called fields), but as far as I have understood it, it does not do what I need. Basically, I have a set of data that describe some measured, dependent variable as a function of a number of controlled variables, in casu z=f(x,y). What I need is to obtain some f that...

Up to now I have got the base R and about half of the packages working on SuSe Linux 5.3 using gcc, g77 and xdevel. The other half, for example: pspline, logspline, KernSmooth, akima, tripack, ppr, principal.curve, cluster, funfit, repeated, event, etc., just won't install. Some of them give warnings at expressions in subroutines (repeated, event, pspline,etc.. I will ask about this in another mail) but a number give 'Assembler messages'. Of these I will quote an install log for 'akima' in full: ..........

...handled via the make variable FLIBS, and that `-lf2c' or `-lg2c' are added by default if g77 is used. This will not solve problems in packages which use their own Makefile if it does not use FLIBS for building the shared library. Currently, this seems to be the case with acepack akima funfits growth leaps tripack It would be great if the package maintainers could update their pkgs accordingly. Most likely, the best solution is to remove the Makefile altogether. Thanks -k -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-devel mailing list -- Read h...
