Prof. Brian Ripley solved the problem. He wrote: > I was not aware that this works with relative paths for any version > of R. Try using a full path, which always works for me. I tried it using a full path, and bingo! It worked like a charm. Under Unix the relative path also works, but. Prof. Ripley also remarked: > If indeed your filesystem is readonly, you will have problems

When i am create new project "rails new newProject", ruby create rails files and next automaticly launch bundle install and setup standart gems: C:\Sites>rails new demo create README.rdoc . . . create vendor/plugins/.git run bundle install . . . Where is standart gemfile location? Or how change standart set of gems? --

Hi, I've seen that some packages use .packageName internally to infer their own name. Is that officially supported? I could not find it documented anywhere. There's utils::packageName(), which internally looks for .packageName. However, if the latter is not found, it may return NULL whereas an error would be more appropriate if a package name is expected. Using .packageName would give

Hi, i want to use Puppet to install all packages from a webserver (no repository) . Therefore I wrote following Script: class install_package { case "$operatingsystem" { SLES: { notify {"${operatingsystem} ${operatingsystemrelease} detected":} notify {"Installing $packagename now:":}

Dear list, this might be an easy one, but I could figure out a solution (or how to google the right term). Is there any way to test whether all elements of a vector are identical? For numeric vectors I would use sum(diff(vector)==0)==0 but I have character vectors. Any Ideas? Cheers Jannis

Continuing to try to customize my environment for using R under Windoze, I experimented with installing a package from CRAN in a local library ``Lib''. I created the directory ``Lib'' in the folder in which R starts, and then executed > install.packages("abind",lib="Lib") Everything went according to form (I got prompted to choose a mirror, etc.) until

Background: OS: Linux Mandrake 10.1 release: R 2.1.1 editor: GNU Emacs 21.3.2 front-end: ESS 5.2.3 Colleagues Since I upgraded to R 2.1.1, I am getting a an error message from R CMD INSTALL packagename that says R_HOME ('/usr/local/lib/R') not found. That's not too surprising, since R is now in /usr/lib/R, but what is confusing me is that R CMD INSTALL -l /path/to/library

Dear list, is there a function in R that returns the product of a vector? E.g. if the vector is c(1,2,3,4) it should return 1*2*3*4=24 Cheers Jannis

Dear R community, I have a general question regarding indexing in multidiemensional arrays. Imagine I have a three dimensional array and I only want to extract on vector along a single dimension from it: data <- array(rnorm(64),dim=c(4,4,4)) result <- data[1,1,] If I want to extract more than one of these vectors, it would now really help me to supply a logical matrix of the

Dear list members, I frequently program small scripts and wrap them into functions to be able to check them with checkUsage. In case these functions (loaded via source or copy pasted to the R console) use functions from other packages, I get this error: no visible global function definition for ?xxxxxxx? For example: test = function() { require(plotrix) color.legend() }

Hi All, I am encountering the following error while performing check on the R package we built: R CMD check packagename_0.99.0.tar.gz During startup - Warning message: Setting LC_CTYPE failed, using "C" * using R Under development (unstable) (2013-05-14 r62742) * using platform: x86_64-unknown-linux-gnu (64-bit) * using session charset: ASCII * checking for file

Dear list memebers, I am stuck with using regular expressions. Imagine I have a vector of character strings like: test <- c('filename_1_def.pdf', 'filename_2_abc.pdf') How could I use regexpressions to extract only the 'def'/'abc' parts of these strings? Some try from my side yielded no results: testresults <-

Dears, a way to define x and y positions in plots in relative numbers (e.g in fractions between 0 and 1 referring to relative positions inside the plot region) would really help me. One example I would need this to would be to add text via text() to a plot always at a defined spot, e.g the upper left corner. Until now I always determined maximum x and y values and used those, but defining

Dear list, I am trying to understand and use the ff package. As I had some problems saving some ff objects, and as I did not fully manage to understand the whole concept of *.ff, *.ffData and *.RData with the help of the documentation, I tried to reproduce the examples from the help of ffsave. When I ran, however : (copied from the help) message("let's create some ff objects")

R CMD check --use-valgrind <packagename> used to run valgrind on the tests in the tests directory of the package. But it seems to have stopped. R-2.9.1 doesn't -- at least on my box -- and neither does R-2.10.0 (devel). I am not sure when this stopped. I think 2.8.x did this. The only old R I have around is 2.6.0 and it certainly does. R CMD check --help for 2.9.1 says (among other

Hey R folks, i found some strange (to me) behaviour with chron to POSIXct conversion. The two lines of code result in two different results, on ewith the correct time zone, one without: library(chron) as.POSIXct(chron('12/12/2000'), tz = 'UTC') as.POSIXlt(chron('12/12/2000'), tz = 'UTC') Only the code below would give me a POSIXct object with the correct time

Dear List, does anybody has experience with the RNetCDF package? I manage to open a connection and copy data from a ncdf file but would need a way to automatically retrieve variable names (ideally all of them from one file) and units from the file. Any ideas? Jannis

Dear list members, is it possible to set some options only inside a function so that the original options are restored once the function is finished or aborted due to an error? Until now I do something like: dummy=function() { old.options=options(error=dummy1()) .... options(old.options) } This works for most cases but when the function terminates because of an error and its last

Dear R developers, as far as I understand the manual of list.files(), there is only a way to exclude directories from the returned vector if you use list.files recursively. In non recursive mode, there seems to be no way of excluding directories (the include dirs argument does not seem to have any effect). Would it not be more intuitive and practical to allow the switching off of directory
