similar to: file.info() on file larger than 2GB

Hi all, I am a PhD student and I am working on a C project that involves some statistical calculations. So, I tried to embed R into C, in order to call R functions from a C program. My program seems to get the correct results from R. However, it appears to have a lot of memory allocation issues, in contrast to the small amounts of memory that my code allocates. Some additional info

*Summary: * During package loading the library function calls file.info to determine if a file is a directory. This uselessly invokes getpwuid and getgrgid which can be expensive if the user/group database are held on a network. Note that file_test ALSO uses file.info for the same purpose Suggest rebuilding file_test to use ‘stat’ based call for directory search, and using file_test in

The other day I was working on an example which used tempfile() to create file for use by the graphics device. And while I love tempfile()---as it is portable and clever and the files get cleaned by R and all that---I noticed one missing feature I would like to see: beside a starting name pattern, and an optional directory, an 'file extension' argument would be nice to have. As e.g. in

Hi, Recently I noticed file.copy() would discard the file mode information. Is this the expected behaviour or a bug for file.copy()? > file.create('testfile') [1] TRUE > file.info('testfile') size isdir mode mtime ctime testfile 0 FALSE 644 2011-03-05 17:06:39 2011-03-05 17:06:39 atime uid gid uname grname

Dear All, I am trying to compile R-3.0 on Cray xe6 (HLRS) HERMIT, no success so far. Here is my experience: I use this to configure and make R: CC="cc" \ CXX="CC" \ F77="ftn" \ FC="ftn" \ CPPFLAGS="-I$PREFIX/include" \ LDFLAGS="-L$PREFIX/lib${LIBDIRSUFFIX}" \ ./configure --prefix=$PREFIX \ --exec-prefix=$PREFIX \ --bindir=$PREFIX/bin \

Greetings, I run an automated process from cron that uploads a large file from my HP/UX server to a PC running Windows 2000 weekly. The process began to fail once the size of the uploaded file gre to over 2GB in size. I've upgraded the Samba 2.2 installation to Samba 3.0.10 but that hasn't fixed the problem. We are running NTFS filesystems on the Windows server. From what I

I'm trying to understand why as.Date() is converting a the modified date of a file from August 22 to August 23. > foo <- file.info(file.to.process) > str(foo) 'data.frame': 1 obs. of 10 variables: $ size : num 5.37e+09 $ isdir : logi FALSE $ mode :Class 'octmode' int 436 $ mtime : POSIXct, format: "2010-08-22 23:14:52" $ ctime : POSIXct, format:

I have a source file with oxygen-style comments (and description & licence files), and I?m trying to build a package. oxygen & devtools seem to work, and the tarball exists, but install.packages balks. Does anyone know what?s happening? Regards, Jorgen Harmse. > roxygenise(package.dir,clean=TRUE) Setting `RoxygenNote` to "7.3.1" ? roxygen2 requires "Encoding:

Sorry - I suspect this is a very basic query. I have a data frame structured "flat" (i.e. separate observations for a given subject ID on separate lines). Using the nlme library I create a groupedData object suitable for further analysis thus: dataset <- groupedData(VARIABLE ~ TIME|ID, data=sfa) The dataset has a large number of VARIABLES of interest so I want to make use of loops

The system.file() and .path.package() functions appear to be unaware of package versions and can return incorrect information or fail if a package is installed using `installWithVers = TRUE' of install.packages(). For example, I can run > install.packages("session", "~/R-local/libs", installWithVers = TRUE) and > library(session, version = "1.0.1")

I have just uploaded a package to CRAN called `gpclib' for clipping large and complex polygons. This package provides an R interface to Alan Murta's very fast General Polygon Clipper library (written in C), which has an optimized version of the Vatti algorithm. Not all features of Murta's library are implemented -- right now you can do intersections, differences, and unions. There

When I build R-devel (or the alpha snapshots) on a system without makeinfo >= 4.7, I get a warning about not being able to build HTML/Info help pages after running 'configure' (but 'make' runs smoothly and there are no errors). However, when I run 'make install' I get an error, something like make[2]: Entering directory

Has anyone tried to build r-devel on a RedHat 7.1 with the gcc 3.1.1 compiler? I didn't have problems with gcc 2.95.x or gcc 3.0.4, but when I ran the configure with gcc 3.1.1 I got the following error: [...] checking whether gcc accepts -M for generating dependencies... yes checking whether gcc supports -c -o FILE.lo... yes checking how to get verbose linking output from g77... -v checking

I am not a member of the samba listserv, but I wanted to contribute the following code to the samba effort. The following is clipped from some experimental changes I have made to my own copy of the samba source. I have not included all of the changes because I don't have the time to. But someone should be able to properly do the integration without too much effort. Summary, these

Hello, The documentation for the tar command leads me to think there is an internal implementation when the command can't be found in the OS. However, it doesn't seem to be the case, as I get an empty .tar file generated on a small example I made : > dir(pattern = "jpg") [1] "MA56237502_635.jpg" > file.info("MA56237502_635.jpg")

In R 1.9.0 on Solaris/Sparc when I run, for example, install.packages("gregmisc", "~/R-local/lib"), instead of installing the `gregmisc' package in the directory /users/student/rpeng/R-local/lib the package gets installed in /users/student/rpeng/\~/R-local/lib, so the directory \~ is created in my home directory. This doesn't happen to me on Linux or Windows so I

Hi, I'm using Debian unstable, with kernel-image-2.6.8-1-686-smp 2.6.8-10, and samba 3.0.10-1. I smbmount a Windows 2003 share with MP3s. The DC is Windows 2003 in mixed mode. When playing many of these MP3s, there is a noticable delay and the following messages are logged into /var/log/message: Dec 22 13:03:24 roller kernel: smb_add_request: request [c0b0f660, mid=22535] timed out!
