similar to: possible minor doc clarification?

Hi Folks, I'm trying to learn R. One of my intentions is to do some Monte-Carlo type modelling of road "accidents". Below, to simplify things, I've appended a little program which does a 'monte-carlo' type simulation. However, it is written in a way which seems a bit un-natural in R. Could someone help me make this a bit more R-ish please? Or is there a

Is there a function in R to calculate the generalized determinant of a singular matrix? - similar to the ginv() used to compute the generalized inverse. I can't seem to find any R related posts at all.

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

Good evening, Spotted a very minor spelling mistake in the source for the grep help. And thanks to R-Core for all their work - it's a tribute to R-Core, that these sort of "problems" are rare indeed.

Good afternoon, This is possibly a windows only bug, definitely of comparatively low importance - but for the sake of completeness here we go. I've searched http://bugs.R-project.org/ etc., but can find no mention. For RGui.exe, the CPU usage goes to 100% for certain dialog boxes for the duration that the dialog box is visible, e.g. * check CPU usage is low * On the RGui.exe menu chose

Good morning, I have currently 63 .csv files most of which have lines which look like 01/06/05,23445 Though some files have two numbers beside each date. There are missing values, and currently the longest file has 318 rows. (merge() is losing the head and doing runaway memory allocation - but thats another question - I'm still trying to pin that issue down and make a small repeatable

Good morning, I've searched high and low and I've tried many different ways of doing this, but I can't seem to get it to work. I'm looking for a way of vectorising a "running balance"; i.e. the value in the first row of the dataframe is zero, and following rows add to this running balance. This is easy to write in a loop, but I can't seem to get it working in

I had the same thought in the shower this morning but I was disappointed to find that SElinux was disabled on the system. My next step will be to install a previous version of R on the system. My problem is that I am planning a shiny server installation and at least half of the apps on the current system depend on these libraries that will not install. -- W.

Hi, i'm running Samba 4.2.1 compiled from source on an Ubuntu 10.04.4 LTS Server. ACL/XATTR is active and working. I tried to activate the vfs_fruite module and added the sample code: vfs objects = catia fruit streams_xattr fruit:resource = file fruit:metadata = netatalk fruit:locking = netatalk fruit:encoding = native to the share. In addition i tried the following share definition: vfs

Good morning, Is there a way to get table() to default to including NAs - as in... table(..., useNA='ifany') or table(..., useNA='always') or table(..., exclude=NULL) ? I can't see a way under table() or options() or searching the archives (probably using the wrong keyword?). > t1 <- c(1,2,3,3,3,2,NA,NA,NA,NA) > table(t1) t1 1 2 3 1 2 3 I keep forgetting to

I am using debug on the .install_packages function...stepping through. Once the temporary folder is created and the tar file expanded I run file_test and get a FALSE back indicating that the configure file is not executable.

Hi! I'm trying to use lm(y~x) amongst others in an automated way; I've gone through the section on indexing in R-lang and I've looked MASS4. How do I find out more about the structure of the returned object? In perl I can look at object structure pretty-printed in the debugger - is there an R equivalent? I've used coef(lm(y~x))[[1]] and coef(lm(y~x))[[2]] to extract the

Hi, I want to introduce "Proxmox" as new value in $::operatingsystem. "Proxmox" is based on Debian, so the normal value is currently "Debian". To change that, I just write a custom fact based on the facter fact "operatingsystem" Facter.add(:operatingsystem) do > ... > setcode do > ... > elsif

Working on Windows I have had to deal with CSV files that, unfortunately, contain embedded Control-Zs, i.e. ASCII character 26 in decimal, and the readLines() function in R on Windows (2.15.2 and 3.0.0) appears to truncate at the control-Z. There is no problem at all on Ubuntu Linux with R 3.0.0. Am I mistaken or is this genuine? # Create a small file with embedded Control-Z h3 <-

Attached is the current version of my sd2rd perl script. It has passed tests by Martin, Fritz and myself, and seems to work reasonably well (it should get the arguments lists right, distinguish between VALUE and VALUES, and know about REFERENCES and SEEALSO). Any comments etc are most welcome. -k ************************************************************************ #!/usr/bin/perl -w $\ =

Hi, I'm trying to R CMD check a package, however I have hit a snag. There seems to be a problem with the creation of the /html files (the only file that's constructed here is the 00Index.html). I've tested each of the .Rd files independently with R CMD Rdconv, they all happily create html files without complaint. R CMD check <package> gives the no warnings. I'm therefore

Hi all, Have been looking at lucene and ferret. Have noticed that ferret takes ~463 seconds to index 200Mb of docs, whereas lucene takes ~60 seconds. I''m using the standard "get you started" sort of code provided by both libraries. My ruby code is: (abridged) @index = Index::Index.new(:path => inIndexPath) def createIndex(inRepositoryPath)

Here?s a patch that adds ?seealso? entries to Sys.time and system.time docs, to help people who forget what the distinction is between them. Patch was made against https://svn.r-project.org/R/trunk at 61454 . -Ken
