Check errors using R2.6.2
I can successfully "check" a package with source under 2.5.1, including compiling source files and running examples with no errors or warnings. when I try with R2.6.2, I get make errors: making bayesmc.d from bayesmc.c make[3]:gcc-sjlj: Command not found etc. my gcc is version 3.4.2 I'm using Windows XP. Any thoughts? thanks! peter r ................................ Peter

.Call question
Writing R Ext says to treat R objects that are arguments to .Call as read only (i.e. don't modify). I have a long list of lists that and I want to avoid the overhead of a copy in my C code. I would just like to modify some of the elements of list by replacing them with elements of exactly the same size/type. below is an example of the essence of the problem. This seems to work. Is this

run-time of an R function
I have noticed dramatic differences in the run-time for the execution of one of my functions depending on whether or not R was restarted. Immediately after restart of R GUI, exec time = 2.8 min. If I then repeat the execution of the function in the same R session, exec time = 7.1 min. Removing all objects via rm(list=(all=TRUE)) and initiating gc (gc(reset=TRUE)) helps, but only slightly (exec

S3 vs S4 classes
I have developed a package, bayesm, which uses existing classes of objects. I would like to add a new class corresponding to objects from this package. I have been reading about classes and all sources tell me that I should use so-called "new" or S4 classes. However, a major purpose of defining a class for my package would be to add methods to the existing generic functions: print,

package submission and binary versions
Dear r-help- >From reading the CRAN web page, it appears that you should not submit precompiled binary versions of your package, but rather that these are built for you by someone working with CRAN. I submitted my package using R CMD build but without the binary flag on. I'd like to have a binary version available for Windows users. Should I submit a precompiled binary version as well?

memory
To whom it may concern, I seem to be encountering RAM problems using R. I am currently running R 2.2.0 in Windows XP version 2002. My computer has 4 GB of RAM. The problem I am encountering is that R does not seem to allow me to obtain more than 1.5GB of RAM as I construct various matrices. I have already pre-allocated 3.5 GB of RAM as in the command line I entered under

Reading data
Hi User's, This might be a simple question but it is giving me a hard time as I am a new user. I installed R version 2.9.2 (2009-08-24) 1. I just copied a short script from Fox (2002) as a practice and wanted to save it as Rossi.R. The system saved it without complain but when I looked at using a windows explorer it is not *.R file but only Rossi. Why this is happening? 2. the script
