Hi everyone: Polyclass is a polytomous logistic regression model using linear splines and their tensor products. It provides estimates for conditional class probabilities which can then be used to predict class labels. I know there is Polyclass package in S-plus. So I'm wondering if there is a corresponding package in R? I have been searching for it for quite a while, but still

Friends, I changed one line of a package at the source level and then rebuilt it. When I run R CMD check, I get an error: installing R.css in C:/polsplineRS.Rcheck ---------- Making package polsplineRS ------------ adding build stamp to DESCRIPTION making DLL ... making hareall.d from hareall.c making heftall.d from heftall.c making lsdall.d from lsdall.c making lspecall.d from lspecall.c

Hi, I am working on a modeling project for PMI-Australia and interested in using R, especially POLYMARS or PLYCLASS. I use SAS /PC on WINDOWS for the statistical analyses including Modeling. I got R downloaded to the system but can't figure out how to interface with SAS so that I could use SAS datasets already in place. Also I could not find POLYMARS on the library packages. I need to know

I was able to hack the code in the polspline package in order to change the plot.polymars function so that I can set the limits of my y-axis. However, I was only able to do this by entering plot.polymars in R, copying the code to Word, changing what I needed, and then pasting the new code in R to redefine the polt.polymars function. I was able to successfully change the function, but now I would

Hi.., is there a function in R to fit bivariate splines ? I came across 'polymars' (POLSPLINE) and 'mars' (mda) packages. Are these the one to use or are there other specific commands? Thanks. Harsh

Hello, Everyone, I am a student an a new learner of R and I am trying to do my homework in R. I have 10 files need to be read and process seperately. I really want to write the codes into something like "macro" to save the lines instead of repeating 10 times of similar work. The following is part of my codes and I only extracted three lines for each repeating section. data.1 <-

Hello, Apologies if this question has already arised, hope you can help me to the find the solution to this or point the place to look at. I have a multidimensional piece-wise regression linear problem, i.e. to find not only the regression coefficients for each "interval" but also the beginning and ends of the intervals. To simplify it to the one dimensional case and two intervals,

Dear All; I have used fbmSim to simulate a fbm sequence, however, when I tried to estimate the Hurst effect, none of the nine procedures gave me an answer close enough to the real value, which is 0.5 (n=1000). So, would you please advice, 1. which is the best method to estimate the H among the 9 mehods, R/S, higuchi or Whittle? 2. how to choose the levels (default=50), minnpts, cutoff values or

Hello all, I'm trying to find out how to perform a 'segmented regression'. I have some data and the 'classical' model used is: y(t) = a + bx(t) + cx(t)^2 + u(t) for x(t) < x(0) y(t) = a + bx(0) + cx(0)^2 + d(x(t) - x(0)) + u(t) for x(t) > x(0) and u(t) = rho.u(t-1) + eps (It's a model using an ARIMA-model, in this case AR(1)-process) The parameters to estimate here

Hi there, Does R has built-in codes for nonpara. bivariate regression so that I can estimate the joint distribution of two variables as a function of some covariates?

Sorry, I can't reproduce the example below even on the same machine. However, the following example produces the same error as NULL values in prior examples: > setClass("FOOCLASS", +????????? representation("list") + ) > ma = new("FOOCLASS", list(M=matrix(rnorm(300), 30,10))) > isS4(ma) [1] TRUE > data.frame(a=1:3) == ma Error in

Hi All, I can't quite figure out how to change the parameters of the x and y axes when I plot a polymars object. I want to add a scatterplot of the data points, but the polymars plot seems to automatically set the parameters to fit the polymars line. I've tried using plot(poly,1,fig= c(x1,x2,y1,y2)) but have no luck. Any thoughts? Thanks, Ryan

Does the polymars library exist anymore?

I have a problem, everytime I plot in pdf, I could only draw in one page, does anyone know how to generate more than one page for example, I have 10 pics to plot in pdf, each page only could be plotted 5 pics, so how can I generate just one pdf of 2 pages, instead of two pdf Thank you -- Xiaogang Yang Sensorweb Research Laboratory http://sensorweb.vancouver.wsu.edu/ Washington State
