similar to: how lambda is computed in smoot.spline given _df_

I've had a play with this and, due to my own short-comings, remain none the wiser. In particular, I'm not sure what value of 'spar' is consistent with the magic lambda=1/1600 for quarterly data. I initially interpreted spar as lambda and tried setting spar=1/1600. This results in almost no smoothing while spar=1600 causes an error. The smooth.spline function seems to want

Hello, I come from a non statistics background, but R is available to me, and I needed to test an implementation of smoothing spline that I have written in c++, so I would like to match the results with R (for my unit tests) I am following http://www.nabble.com/file/p25569553/SPLINES.PDF SPLINES.PDF where we have a list of points (xi, yi), the yi points are random such that: y_i = f(x_i) +

Dear list, if I do smooth.spline(tmpSec, tmpT, all.knots=T) with the attached data, I get this error-message: Error in smooth.spline(tmpSec, tmpT, all.knots = T) : smoothing parameter value too small If I do smooth.spline(tmpSec[-single arbitrary number], tmpT[-single arbitrary number], all.knots=T) it works! I just don't see it. It works for hundrets other datasets, but not for

Can someone please show me how to smooth time series data that I have in the form of a zoo object? I have a monthly economies series and all I really need is to see a less jagged line when I plot it. If I do something like s <- smooth.spline(d.zoo$Y, spar = 0.2) plot(predict(s,index(d.zoo)), xlab = "Year") # not defined for Date objects and if I do something like

Everyone, One of our developers was kind enough to insert some bug checking into the mod_auth_pam and mod_auth_sys_group so that we could see a little more of what was going on with our authentication failures. Here is what we just saw. Two of our users NA\connelmp and NA\guminssa both started getting messages that they were not part of the required group. Here is the log for

Hi r-helpers. Please forgive my ignorance, but I would like to plot a smoothing spline (smooth.spline) from package "stats", and show the knots in the plot, and I can't seem to figure out where smooth.spline has located the knots (when I use nknots). Unfortunately, I don't know a lot about splines, but I know that they provide me an easy way to estimate the location of local

Dear R-helpers: (this is part of a bigger program) the following fails as a function, but runs OK if we comment out the fnfn_ function() line. Any hint would be appreciated. -Yudi- R : Copyright 1998, The R Development Core Team Version 0.63.0 Beta (Nov 13, 1998) -- on WIndows3.11 fnfn _ function (m=10,n=10,spar=2) { fn _ function(u,v){ uc_ u-floor(m/2)-1 vc_ v-floor(n/2)-1

Everyone, Here is a challenge for all of you samba experts! Lately I have been seeing a problem where winbind is not correctly identifying a user as a member of a group he most certainly belong to. This is with a Domain Local group so I know samba should support it. Users access a HTTPS (SSL) webpage that is secured by a Domain Local group. Sometimes they get in,

Hi, I am having an issue with a custom panel for lattice. The problem comes when I try passing a groups argument. Here is the custom panel, a wrapper for smooth spline. I copied panel.loess and replaced the loess arguments with smooth.spline(). [Note: I would like to use the cross-validation fitting properties of smooth.spline.] library(lattice)

Hi is it possible to fit a trend line (or some other panel function) through each of multiple data series plotted on the same graph? Specifically, while one can do something like xyplot(a+b+c~x) which plots three series, a,b & c, but can one automatically fit lines through each of them? I suppose one could generate three more variables afit, bfit, and cfit with a model & predict and

Hi, I am trying to compile R-2.2.1 on Solaris 2.9 with a 64-bit build. Following the instructions in "R Installation and Adminstration", I changed the following settings in "config.site": CC="gcc -m64" F77="g77 -64" CXX="g++ -m64" LDFLAGS="-L/usr/local/lib/sparcv9 -L/usr/local/lib" But I got the following error messages:

Dear R listers, When using smooth.spline to interpolate data, results are generally good. However, some cases produce totally unreasonable results. The data are values of pressure, temperature, and salinity from a probe that is lowered into the ocean, and the objective is to interpolate temperature and salinity to specified pressures. While smooth.spline provides excellent values at the

Hi, Would like to use to the hexbin package to plot a 2D hist - because it looks really _cool_. My problem is related to drawing a pdf hexbin graphic in series of other graphics. All other figures have a par(mar=c(3.2,3.2,1,1)). So the gplot.hexbin figure in this series looks a little alienated? Was trying a to specify the _mar_ using par, viewport, hexViewport etc. a little. My question. How

Hi! I am trying to calculate a dissimilarity matrix using daisy. The matrix vectver is binary as i test with: > levels(as.factor(vectver)) [1] "0" "1" But the call to daisy gives me the following error message.: > dfl1 <- daisy(vectver, type = list(asymm = c(1:length(vectver[,1])))) Error in daisy(vectver, type = list(asymm = c(1:length(vectver[, 1])))) : at least

Hi! On the cran "package source" page, to each package there are the "reference manual" in pdf format with a nice title page. I observed that during the R CMD check pkg a pkg-manual.div are generated in the pgk.Rcheck directory. But the nice title page are missing. During the package build and install no div files are produced. Which opitions I have to pass during the build

To whom it may concern, I don't know whether this is really a bug with the Pspline package or only a problem with my installation. Things work fine in Linux but not in Mac OS X (Darwin). Both system run the latest public versions of R and Pspline. predict.smooth.Pspline produces only NaN instead of predicted values when norder>2: > library (Pspline) > tt <- seq

Dear All, I know how to export graphics as pdf files and then how to include them in LaTeX documents. However, I do not know how to do in order to have the text of the graphics written with the font selected for the LaTeX document. Is that possible? Thanks in advance, Paul
