Hello, I would like to compress a long string (character vector), store the compressed string in the text field of a SQLite database (using RSQLite), and then load the text back into memory and decompress it back into the the original string. My character vector can be compressed considerably using standard gzip/bzip2 compression. In theory it should be much faster for me to compress/decompress

Hi, I have zlib compressed strings (example is attached) and would like to decompress them using memDecompress ... I try this: > connection <- file("compressed.txt","r") > compressed <- readLines(connection) > memDecompress(as.raw(compressed),type="g") Error in memDecompress(as.raw(compressed), type = "g") : internal error -3 in

Hi all, I'm struggling to decompress a gzip'd raw vector in memory: content <- readBin("http://httpbin.org/gzip", "raw", 1000) memDecompress(content, type = "gzip") # Error in memDecompress(content, type = "gzip") : # internal error -3 in memDecompress(2) I'm reasonably certain that the file is correctly compressed, because if I save it

Hi, I get the same error as mentioned in http://r.789695.n4.nabble.com/error-in-memCompress-in-make-check-td3318922.html I try to compile R 2.12.2 under Tinycore 3.5.1 running in VirtualBox 4.0.4. Since first xz was not installed I must have used the internal version which comes with the R source tar ball. But after installing the xz 5.0.0 extension the error remained. Any idea what else I

hello everyone: On this boring weekend, I tried compile R-trunk on windows 11 arm64 using clangarm64+msys2 on macbook m1 , it surprisingly easy to compiled and run. more investigation and test and code modify need to be done ,but IMO this is a good beginning !! to compile R on windows 11 arm64 just need : 1 svn checkout R-trunk and add USE_LLVM=YES in MKRules.dist or Mkrules.local 2 install

I've just updated to R 4.0.2 but am unsure how to get packages from the COPR repository to update to those built under the new version of R. FI - I'm not currently using CoprManager just trying to update/install from terminal. Regards Tim [[alternative HTML version deleted]]

Could someone explain what is happening with the ...() of the following function: dots <- function(...) as.list(substitute(...())) I understand what I'm getting as a result but not why. ?dots and ?substitute leave me none the wiser. regards Tim

Hi Ivan, An apology, I was away for quite a bit. To reproduce the setup: I have been using the default GCC in RHEL 9.1. gcc -v Using built-in specs.

Dear Miguel Esteva, I couldn't get a Red Hat "ubi9" container to install enough dependencies to build R. Is there a way to reproduce your setup on a virtual machine somewhere?

I've rolled up R-2.11.1.tar.gz a short while ago. This is an update release, which fixes a number of mostly minor issues. The most annoying one was probably the problem with format.POSIXlt causing C stack overflow on long date vectors. See the full list of changes below. You can get it from http://cran.r-project.org/src/base/R-2/R-2.11.1.tar.gz or wait for it to be mirrored at a CRAN site

You need to understand what substitute() does -- see ?substitute and/or a tutorial on "R computing on the language" or similar. Here is a simple example that may clarify: > dots <- function(...) as.list(substitute(...())) > dots(log(foo)) [[1]] log(foo) ## a call, a language object > dots2 <- function(...) as.list(...) > dots2(log(foo)) Error in as.list(...) :

I probably need to be more specific. What confuses me is not the use of substitute, but the parenthesis after the dots. It clearly works and I can make guesses as to why but it is definitely not obvious. The following function gives the same final result but I can understand what is happening. dots <- function (...) { exprs <- substitute(list(...)) as.list(exprs[-1]) } In the
