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")

I noticed that if I specify the location of TMPDIR in .bashrc as follows on a Linux 64 bit system: export TMPDIR=/store/home/ayee/.tmp I get the following error message when installing R make[3]: Entering directory `/home/ayee/R-patched/src/library/base' building package 'base' make[4]: Entering directory `/home/ayee/R-patched/src/library/base' /bin/sh: line 8:

Hi, Recently I noticed file.copy() would discard the file mode information.

I've got a file that's approximately 2.2GB and it seems to be foiling file.info().

I was trying to remove a directory and couldn't figure out why it was failing: > dir("~/p4/r-packages/IREval/Users", recursive=T) [1] "u0048513/p4/r-packages/IREval/DESCRIPTION" [2] "u0048513/p4/r-packages/IREval/R/IREval.R" [3] "u0048513/p4/r-packages/IREval/Read-and-delete-me" [4] "u0048513/p4/r-packages/IREval/tests/general.R" >

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

Hi, I'm trying to remove/delete a directory usingR. I've tried the following with no success: % Rterm --vanilla > getwd() [1] "C:/Documents and Settings/hb/braju.com.R/aroma.affymetrix/test" > dir.create("foo") > file.info("foo") size isdir mode mtime ctime atime foo 0 TRUE 777 2007-02-28 14:52:10

Are there any tricks associated with file.info? I just tried it on a directory folder and it returned NA for all fields for all files. I tried it on a different folder with different files and it still returned NA. I tried it on a specific file and it returned all the proper info correctly. Just wondering if there are any tricks I've overlooked.

There seems to be a bug with var() when the argument is a vector with exactly three values of 1e30 (or close to this value). This does not happen with twice, four (or more) times this value, or another value. > var(rep(1e30, 3)) [1] 2.971056e+28 > var(rep(1.2e30, 3)) [1] 2.971056e+28 > var(rep(0.9e30, 3)) [1] 2.971056e+28 > var(rep(0.8e30, 3)) [1] 0 > var(rep(1e29, 3)) [1] 0 >

(R 2.8.0 on Debian GNU/Linux sid) ?file.info contains: mtime, ctime, atime: integer of class '"POSIXct"': file modification, creation and last access times. This implies that ctime is "file [...] creation [...] time" Has R implemented ctime differently to Unix? I understand, on Linux at least, that ctime is the last change time (not the creation time).

Dear R-helpers, I am trying to generalize my function for recording measurement times from file times "mtime"--my intervals are minutes to hours over the course of several days. I want to use hours as my units, and I have had trouble dealing with time units in a general way. I have a simple solution for the dealing with regular intervals, but I have not been able to handle irregular

Hi, I have a writable and readable file on a small network file system (Cisco NSLU2 Unslung; non-NTFS) that I access via a mounted drive on Windows Vista. My problem could be due to a "funny" file system/server, but here it goes: > pathname <- "Q:/foo.txt" > cat(file=pathname, "Hello world!\n") > readLines(pathname) [1] "Hello world!" >

Dear all, How can I get the duplicated elements from a vector? For example, x <- c("yes", "no", "yes", "yes", "no", "not sure"), how can I filter out all the elements which occured >=2 times? Thanks for any help! Regards, Leon

In a number of places internal to R, we need to know which files have changed (e.g. after building a vignette). I've just written a general purpose function "changedFiles" that I'll probably commit to R-devel. Comments on the design (or bug reports) would be appreciated. The source for the function and the Rd page for it are inline below. ----- changedFiles.R: changedFiles

Was trying to understand more about the internals of wxruby-swig, where does the big chunk of XML comes from? I saw something similiar in Python, is that massaged out of there? The codes produced by extractxml.rb and wxclasses-2.4.2.xml is quite different from the original header files. Just for example the WxDialog class. OnXXX are non-virtual in WxWidgets, but virtual in wxruby-swig
