Package repository on Linux machine and upgrading R
Dear list, I remember running into a thread on this topic in one of the R mailing lists before but I can't seem to find it now. Basically, I remember a discussion on how one can set up where R packages can be installed so that when we upgrade the R version on the machine, the packages are still accessible. One can back up this package location as well and bring it to a new computer. I

proportion of treatment effect by a surrogate (fitting multivariate survival model)
Dear R-help, I would like to compute the variance for the proportion of treatment effect by a surrogate in a survival model (Lin, Fleming, and De Gruttola 1997 in Statistics in Medicine). The paper mentioned that the covariance matrix matches that of the covariance matrix estimator for the marginal hazard modelling of multiple events data (Wei, Lin, and Weissfeld 1989 JASA), and is implemented

build 32-bit R on x86_64?
Dear R-Devel, I'm using Ubuntu on an x86_64 machine and would like to have both the 32-bit and 64-bit versions of R built from source. By default, following the usual build procedures yields 64 bit R. Looking at [these](http://cran.r-project.org/doc/manuals/R-admin.html#Sub_002darchitectures), I thought I could build 32-bit R by executing r_arch=32 ./configure and building R like usual

R + C + Lapack toy regression example
dear list, since matrix manipulations is often of interest in statistical computations, i'd like to get a working example of using Lapack for regression. However, i run into an error. My matrix-lapack-example.c file: #include <R_ext/Lapack.h> void reg(const char* trans, const int* m, const int* n, const int* nrhs, double* a, const int* lda, double* b, const int*

Embedding R's math expressions fonts for graphics generated by pdf() and postscript()
Dear list, First, I am not writing to ask about embedding Computer Modern font in graphics produced by R. I am generating plots to be saved using pdf() and postscript() in R, and I make use of some math expressions that are provided by R, namely, some greek letters. My question is, do I need to embed the fonts that include these math symbols (say, if they are going out for publication, to have

survey package: weights used in svycoxph()
Dear R-help, Let me know if I should email r-devel instead of this list. This message is addressed to Professor Lumley or anyone familiar with the survey package. Does svycoxph() implement the method outlined in Binder 1992 as referenced in the help file? That is, are weights incorporated in the ratio term (numerator and denominator) of the estimating equation? I don't believe so since
