I was attempting to use the residual resampling approach to generate 999 bootstrap samples of alpha and beta and find their confidence intervals. However, I keep getting the error message:Error in nls(resample.mp ~ cases/(alpha + (beta * cases)), start = init.values, : singular gradientafter R has only produced a few bootstraps.Could anyone suggest where I am going wrong? Would greatly

Dear WizaRds, I would like to fit a curve to ten points with nls() for one unknown parameter gamma in the Kahnemann/ Tversky function, but somehow it won't work and I am unable to locate my mistake. p.kum <- seq(0.1,1, by=0.1) felt.prob.kum <- c(0.16, 0.23, 0.36, 0.49, 0.61, 0.71, 0.85, 0.89, 0.95, 1) ## how to find a function that fits these points nicely? plot(p.kum,

I'd like to compare tests based on the mixed model representation of additive models, testing among others y=f(x1)+f(x2) vs y=f(x1)+f(x2)+f(x1,x2) (testing for additivity) In mixed model representation, where X represents the unpenalized part of the spline functions and Z the "wiggly" parts, this would be: y=X%*%beta+ Z_1%*%b_1+ Z_2%*%b_2 vs y=X%*%beta+ Z_1%*%b_1+ Z_2%*%b_2 + Z_12

Estimado Freddy Omar López Quintero Muchas gracias.

Dear expeRts, I it possible to have serif labels in the following plot? x <- 1:10 y <- x plot(x, y, type="b", xlab=expression(x[1]), ylab=expression(x[2])) I know that one can use pdf(, family="serif"), but then also the axis tick marks are printed in serif font. Apart from the fact that it may not look nice, I'm just interested if one can have serif axis labels

Dear R'ers, I have trouble installing tikzDevice in Ubuntu.  When I use install.packages("tikzDevice"), it gives error message: ERROR: dependency ‘filehash’ is not available for package ‘tikzDevice’ * removing ‘/usr/local/lib/R/site-library/tikzDevice’ Then I tried filehash installation, I get the message: "package ‘filehash’ is not available (for R version 2.13.1)"

Hello people! I just formatted my disk, and I have installed R 2.14 over. Now I am trying to restore my packages and all. I realized that tikzDevice, a crucial package for me is gone. Fortunately, I have kept my old, non-zipped, tikzDevice folder, but none of the commands I know seems to handle this [i.e. load() and install.packages()]. Thus the formulation is like this: how to install a

Dear All, I am starting to use the tikzDevice package, but I am experiencing some (minor problems). If I try to run the script at the end of the email, I get the following error Error in tools::texi2dvi("normal.tex", pdf = T) : Running 'texi2dvi' on 'normal.tex' failed. Messages: sh: /usr/bin/texi2dvi: not found How do I install the missing texi2dvi? I found some

Dear all, I'm trying reproduce an example of bioassays Yielding Concentration-Mortality Data particularly control - adjustment model from book Bioassay of Entomopathogenic Microbes and Nematodes chapter 7 with R. I used glm with family=binomial and link=probit, but I do not know how to implement parameter gamma (control mortality - mortality of the untreated control insect in this exaple)

Hi guys. The tex file which compile the following graphic has many problems. I don't know what's happening. Any input would be really appreciated. # Cargo el prgrama que produce el c?digo en Latex require(tikzDevice) # Establezco directorio del programa setwd('/Users/fabiangarcia/Documents/R') # El siguiente programa produce el archivo tex tikz('CobbGRAF.tex',

Hi all, I can't fathom why the accented "?" in the following ggplot2 graph makes R hangs when using tikzdevice,? whereas it works using simple pdf device. ###### library(tikzDevice) library(ggplot2) options(tikzDefaultEngine = "luatex") tikzLualatexPackages =c( ? "\\usepackage{tikz}\n", ? "\\usepackage[active, tightpage,psfixbb]{preview}\n", ?

Hi R-core, I was wondering if somebody could please add jsslogo.jpg to the R sources? (as I reported yesterday in this bug) https://bugs.r-project.org/bugzilla/show_bug.cgi?id=17687 R already includes jss.cls which is the document class file for Journal of Statistical Software. Actually, for the jss.cls file to be useful, it also requires jsslogo.jpg in order to compile JSS articles without

Buenos días; Aunque ya llevo un tiempo con LaTeX y R no he conseguido que me funcione la librería tikzdevice. El primer problema está con tikzDictionary que me da como error: cannot create lock file. He estado buscando información en Google pero sin éxito. No he conseguido solucionarlo indicando un archivo en RProfile con options(tikzMetricsDictionary = ''path/archivo''). Cuando

I am having problem making ggplot2, tikzDevice, and knitr working together. I used a very simple example: ---------------------------example.Rnw----------------------------- \documentclass[preview]{standalone} \begin{document} \begin{figure} <<fig1,eval=TRUE,echo=FALSE,dev='tikz'>>= library(ggplot2) qplot(displ, hwy, data = mpg, colour = factor(cyl)) @ \end{figure}

Hi, all, Does anybody got the most general expression of a unitary matrix? I found one in the book, four entries of the matrix are: (cos\theta) exp(j\alpha); -(sin\theta)exp(j(\alpha-\Omega)); (sin\theta)exp(j(\beta+\Omega)); (cos\theta) exp(j\beta); where "j" is for complex. However, since for any two unitary matrices, their product should also be a unitary matrix. When I

Hello R developers, I sincerely apologize if the answer to this question is clearly documented somewhere, but I was unable to figure it out over my morning coffee. I just downloaded today's release of R 2.11.0 and installed it on my Windows 7 64 bit VM. I also downloaded the latest version of Rtools211 from Professor Murdoch's site. The first thing I attempted to do was build some of

I'm trying to use lattice graphics to produce some small plots for inclusion in a LaTeX file. I want the LaTeX fonts to be used in the plots, but to be scaled down to match the size of the plot. I have written the following code to apply a scaling factor to all the "cex" and "padding" entries in the trellis parameters, but there is still a large white space between the key

Me interesa este tema. Estoy empezando ahora a ver el tema de armar documentos directamente con R y no estoy seguro en dónde me centro. Por lo que veo sweave y knitr son las dos grandes alternativas (de echo, no se siquiera si no son compatibles o complementarias). Para quien arranca en este tema y que pretende continuar sobre el mismo, que recomiendan, arrancar por sweave o por knitr?
