As I understand it, sum() treats a logical vectors as 1's and 0's, so that > is.logical(c(FALSE,TRUE,FALSE)) [1] TRUE > sum(c(FALSE,TRUE,FALSE)) [1] 1 However, summing the results of an is.na() yields a negative number. Eg > is.na(c(1,NA,3)) [1] FALSE TRUE FALSE > is.logical(is.na(c(1,NA,3))) [1] TRUE > sum(is.na(c(1,NA,3))) [1] -1 (This is from R Version 0.64.0,

Does anyone know what algorithm R uses in glm, family=binomial (i.e. a logit model)? I assume that it's in the source somewhere, but I wasn't able to find it. I'd like to know what file it's in (in a unix distribution of R). Thanks for your help. --------------------------- Barnet Wagman wagman at enteract.com 1361 N.

I'm have what's probably a trivial &| silly problem trying to access a c-function in a shared library ( R 0.64, under redhat linux 5.2). R COMPILE rctest.c R SHLIB -o libRC.so rctest.o produce a reasonable looking shared library ('nm libRC.so' shows that the function 'rctest' is present). In R, the command dyn.load("/fullpathname/libRC.so")

I wonder if someone could explain how the following R idiom works (it's used in glm.fit). start <- coef start[fit$pivot] <- coef coef is a vector of coefficients, set by .Fortran("dqrls", ...). fit$pivot is a vector of integer indexes (indicating how dqrls permuted the columns of x). If coef has n elements, fit$pivot is a permutation of seq(1,5). start[fit$pivot]

I'm encountering a couple problems configuring and making R 0.64 under linux, redhat 5.2 These problems didn't occur when I build 0.63.2 Any suggestions would be greatly appreciated. (1) configure generates the warning: "configure: warning: Cannot determine how to create shared libraries. Please set CPICFLAGS, FPICFLAGS and SHLIBLDFLAGS in `config.site'." I'm not

For anybody who uses ESS with R, how do you invoke the vsize and nsize options when you call R. I can't find any appropriate variables from an apropos.

Since there doesn't appear to be an RMySQL rpm for SuSE 8.*, does anyone know if the 7.3 version will work with the SuSE 8.2 rpms of R and DBI? The package installs without complaint, but when I try to run con <- dbConnect(dbDriver("MySQL"),dbname="test") I get the error Error in dbConnect(dbDriver("MySQL")) : couldn't find function

According David Jame's response to my earlier question, there is a problem with setGeneric.setMethod in R 1.8.0 that affects DBI and RMySQL. Is there a fix for this? David Jame's refers to an 'R-patched version' but I haven't seen anything like this on CRAN. Would going back to an older version of R solve the problem? Thanks, Barnet Wagman "David James wrote:

I haven't been able to find any documentation explaining what these errors mean (and if they're serious). If anyone can give me some guidance on this, I'd very much appreciate it. The error messages are make[4]: *** [ctest-Ex.Rout] Error 1 make[3]: *** [test-Examples] Error 2 make[2]: *** [test-Examples] Error 2 make[1]: *** [test-all-basics] Error 1 make: ***

He was suggesting to upgrade to 15.10 if you needed the newer fortran for some reason (or other newer things only in backports or not even there). I also mostly run LTS versions of Ubuntu, especially in my research group where I manage our cloud/servers. Which also matches the computer cluster available to me. That said I also stick to the stock packages for all the basic underlying libraries

I encountered a segfault running glm() and wonder if it could have something to do with the way memory is handled in a dual core system (which I just set up). I'm running R-base-2.4.0-1, installed from the SuSE 10.1 x86_64 rpm (obtained from CRAN). (My processor is an AMD Athlon 64 x2 4800+).

I'm doing some work with a weighted data set (the CPS) and I'd like to use nonparametric techniques. Is there an R package that supports this? The np package doesn't appear to have provisions for weighted data. (Or have I missed something?) I need to perform both density estimation and regressions. thanks, bw
