Using Sweave in the tools library (R version 1.8.0: sorry i havent upgraded), it seems i cant use if statements in R chunks that make graphs. i have this: <<fig=TRUE,echo=F>>= par(mfrow=c(1,1)) if(exists("x")) plot(x,x) else{ plot(1,1,type="n") text(1,1,"data not available.\n") } @ and I get this error: Error: chunk 6 Error in parse(file, n,

Ive created a postscript files that looks just like I want it to look except instead of being 6'' x 6'' i want it to be 2''x 2''. i used the postscipt() function (R 1.5.1 on redhat). if i use width and height in par to change the scale the figure looks terrible cause cex,mar,etc.. dont appear to change. before i start tinkering with the cex's and mar... is

im using R 1.5.0 on redhat. when i use ccf in the ts library i get, what i think is, an incorrect entry in the lag and acf components. as an example, look at the second entry in the lag and acf components below: > library(ts) > tmp <- ccf(ts(rnorm(3)),ts(rnorm(3)),plot=F) > tmp$lag , , 1 [,1] [1,] -1 [2,] 0 [3,] 0 [4,] 1 > tmp$acf , , 1 [,1] [1,]

if i write a funciton like this f <- function(x) Sweave("report.Rnw") and report.Rnw has an R chunk like this: <<>>= print(x) @ i get an error: 'Object "x" not found'. is there a way to avoid this without using assign to create a global variable? thanks, rafael

hi! i want to change the "robustness weights" used by loess. these are described on page 316 of chambers and hastie's "statistical models in S" book as r_i = B(e_i,6m) where B is tukey's biweight function, e_i are the residulas, and m is the median average distance from 0 of the residuals. i want to change 6m to, say, 3m. is there a way to do this? i cant

Does anyone know if Hastie's gene shaving method is implemented in R Thanks, Aimin

hi! using: Version 1.8.0 Under development (unstable) (2003-09-02) using the Sweave function of the tools package i get this error when latexing with texi2dvi --pdf ! LaTeX Error: File `upquote.sty' not found. if i change the line \usepackage{/users/faculty/ririzarr/R-1.8.0/lib/R/share/texmf/Sweave} to \usepackage{/users/faculty/ririzarr/R-1.7.1/lib/R/share/texmf/Sweave} in the tex file,

Dear All, Thanks to all that took the time to respond to my questions (included at the bottom). Martin Maechler was nice enough to give me a detailed explanation which he suggested i forward. The confusion arose because if(exists("x")) plot(x,x) else{ plot(1,1,type="n");text(1,1,"data not available.\n")} gave me an error when used as a chunk in a Sweave

Hi! I have used the Matrix package (Version: 0.995-10) successfully to obtain the OLS solution for a problem where the design matrix X is 44000x6000. X is very sparse (about 80000 non-zeros elements). Now I want to do WLS: (X'WX)^-1X'Wy I tried W=Diagonal(length(w),w) and wX=solve(X,W) but after various minutes R gives a not enough memory error (Im using a 64bit machine with 16Gigs
