Dear R list: I want to make separate estimates for each level of the variable "group." After consulting many sources I am stumped as to why the following does not work: > wintemp <- subset(alltemp, winner==1) > my.ppr <- function(x) + { + if(nrow(x) >= 50) { + pprfile <- ppr(award~ilogemp, data=x,nterms=5,max.terms=10,optlevel=3) + summary(pprfile) +

Sorry about the lack of detail. I am running R v.1.2.2. I can recast my question (which I think I have partially answered) more succinctly as follows: 1. This seems to work (note that group takes values 1,2,3,4, or 5): my.newfun <- function(x) myfile <- lm(award ~ ilogemp + ilogage, x) test.by <- by(wintemp, as.factor(wintemp$group), my.newfun) 2. This does not work (leaving aside

Dear R listers -- I have several questions about using the ppr command in the modreg module. I discovered -- quite by accident -- that if I re-order the data, I obtain different results. The output below shows what I mean. I have two datasets (dataset1 and dataset2) that are identical (tested using proc compare in SAS) except for the fact that the records are in different order. Below I have

I used the supersmoother function in the modreg package as follows: super <- supsmu(ilogemp,award) Then I decided that I might want additional explanatory variables (other than ilogemp) in my model. The ppr function in modreg seemed a logical extension of supsmu from univariate to multidimensional explanatory variables. As a "check" I ran the following: pprest <-

I read the mailing list archive about Gigabyte motherboards not working with USB booting ("[syslinux] Gigabyte recent bios & syslinux extlinux trow USB-IDE bridges or pendrives", 16 Aug 2006). I have a Gigabyte GA-MA790GP-DS4H motherboard that I tried to boot in USB-HDD mode with a PNY boot pen. I installed System Rescue CD on it. It would appear that Gigabyte still doesn't

Hi all, I am doing a projection pursuit regression using the ppr() function from modreg. I would also like to use predict.ppr(). However, I cannot find any information about it in the help files. There is a link to predict.ppr in the index for modreg, but that link is to the help for ppr(). Has predict.ppr() not been implemented? If not, does anyone have a suggestion as to how to implement

I'm trying to cross-compile R on a Mac OS X box to target Win32. It works quite well, everything works, except for one fortran file ppr.f in the stats package: ---------- Making package stats ------------ adding build stamp to DESCRIPTION installing NAMESPACE file and metadata making DLL ... i386-mingw32-g77 -O2 -Wall -c ppr.f -o ppr.o ppr.f:803: sorry, unimplemented: data

Hi, Recently, I installed the 1.1.0 version of R (for Windows), since it includes an implementation of Projection Pursuit (I failed to write my own version of PP as a standalone C++ program). As far as I know, R offers two interfaces/sintax for the ppr() function. The first one requieres a regression formula and a data frame. The other requieres X, a matrix with the explanatory variables, and Y,

Dear R users, I am looking for the source code of the implementation of ppr (Projection Pursuit Regression) in R. It will be great if citations of the source papers on which the implementation is based, are also provided. Thank you, Arvind Iyer, Grad student, Deptt. of Biomedical Engineering Viterbi School of Engineering University of Southern California, Los Angeles [[alternative HTML

Hi, I'm running samba 2.2.1a (RPM install) on RedHat 7.2 I've connected a Canon LBP-8 IV laserprinter to the network via a HP Jetdirect box. I've configured the printer within linux and printing goes fine. Now I'm trying to access the printer via samba from my win2k clients. Now, the problem is: When I'm trying to print to the printer (e.g. a testpage) I get the message

The pursuit projection packages ppr is an excellent contribution to R. It is great for one-to-three ridge fits, often somewhat intuitive, and for multi-ridge fits, where it at least describes a lot of variance. Like many folk, I need to report the fits obtained from ppr to the greater, outside, non-R world. It is fairly obvious how to use the terms alpha and beta to report on

Dear all, I have been doing tests using SVM, random forests and PPR. The data is from a data stream (that is, the data for training and for test is always increasing / changing). With SVM and random forests everything is ok, but with ppr there are situations where it crashes. For the examples I have used I noticed that if one of the variables has just one value (it can happen), it crashes for

supsmu(periodic=TRUE) can crash R by reading before start of array. To reproduce: set.seed(1) xx <- runif(29000) yy <- rnorm(29000) span <- 0.49 i <- 1 while(i < 200){ cat(i,"\n") int <- supsmu(xx,yy,periodic=T,span=span) i <-i+1 } results in: 1 2 3 4 5 6 7 8 9 Program received signal SIGSEGV,

hi all , i use ubuntu 12.04 with xcp , all config run very well except vlan i use xe network-create and xe vlan-create to build vlan 3000 then startup a vm in this network, xapi0 fakebridge and vif1.0 all looks well, use ovs-vsctl list port i can see xapi0 and vif1.0 have beed taged with 3000 but i can not access the internent~~~ somebody can help me with this? thanks.

Hopefully the last patch from me to UTF-8 issues. Metaflac can now print all console supported characters from tags on the screen. It also fixes metaflac to be able to import its own exports back without non-ascii characters getting mutilated. And --no-utf8-convert now works properly with import and export commands. I updated my Windows binary archive with these changes for any interested
