similar to: Extract names from vector according to their values

reorder() is probably the best way to order the levels in a vector without manually specifying the order. But reorder() orders by default in an increasing order: "The levels are ordered such that the values returned by ?FUN? are in increasing order." Is there a way to do what reorder() does, but order the levels according to a _decreasing_ order of the values? Sverre

Dear helpers, I'm trying to extract certain rows from a matrix according to the values the rows have in a certain column. I've been googling for a while without result. Here's a reproducible example of a matrix (and the one I was playing with initially): > myrepo<-getOption("repos") >

Dear helpers, how can I extract only the values from a row in a data frame? Using [X,] doesn't do the trick: > data.frame(letters[1:10],letters[11:20])->my.data > my.data[1,] letters.1.10. letters.11.20. 1 a k I would like to be able to extract only the values "a" and "k" without getting the row names and column names with them.

Hi all, I'm extracting the name of the term in a regression model that dropterm specifies as the least significant one, and I'm assigning this name to an object. However, when I use update(), it ignores this object. Is there a way I can make it not ignore it? A reproducible example is below: > lm(x1~1+y1*y2+y3+y4,data=anscombe)->my.lm >

Dear helpers, I'm trying out the embedFonts() to embed fonts into my pdf files. However, when I inspect the new pdf with a program designed to look for embedded fonts, I see that the fonts have in fact not been embedded. Below are my calls.

As recently discussed on Stack Overflow, R for Mac OS and Ubuntu (so probably all Unix systems) can correctly write files with UTF-8 encoding, but R for Windows cannot: http://stackoverflow.com/questions/19877676/write-utf-8-files-from-r I strongly suggest that R for Windows should support this feature in upcoming versions.

Dear helpers, I am not able to export Unicode characters from R. Below is an example where the Unicode character is correctly rendered as long as I am stay within R. When I export it, the character appears only with its basic code, and the same happens when I import it back into R . I'm using R 2.13.1 in Windows XP. > funny.g <- "\u1E21" > funny.g [1] "?" >

Greetings, I've been trying to upgrade R packages on my Debian Etch (whose other upgrades I have been cheerfully going along with as they occur). When I did, just now: sudo apt-get dist-upgrade I got: Reading package lists... Done Building dependency tree... Done Calculating upgrade...

Hi: I installed Lucid Lynx amd64 on my system today, dual booted with Win 7. I've managed to install several packages through the Ubuntu Software Center with success and also installed texlive. Alas, installing my favorite software has not been so joyful. I went through the last few months of posts in this group to find something similar, but to no avail. After a couple of false starts, I

Dear Mr. Beginning to work on Linux. I am trying to install R into Ubuntu Gustsy. I installed version 2.5.1 and worked fine. But then I tried to upgrade by adding these lines to sources.list: deb http://cran.fiocruz.br/bin/linux/debian etch-cran/ deb http://cran.fiocruz.br/bin/linux/ubuntu gutsy/ I introduced the authorization keys (as recommended) and the files were downloaded.

?Startup says: "Note that when the site and user profile files are sourced only the base package is loaded, so objects in other packages need to be referred to by e.g. utils::dump.frames or after explicitly loading the package concerned." So you need utils::installed.packages and utils::install.packages . Duncan Murdoch On 21/03/2023 8:04 a.m., PIKAL Petr wrote: > Dear all.

After Johannes set up the CRAN repository for Jessie, I had quite some trouble figuring out what any user should do to have a running and up-to-date R in Debian (particularly Testing). Part of the problem is, I think, the overwhelming documentation on the page "DEBIAN PACKAGES OF R SOFTWARE" which is provided on CRAN at /bin/linux/debian. Some information is also lacking in places.

Hello All, I'm actually the system administrator of a UNIX system where several users use R version 2.6.0. I have a user who is trying to use the SURVEY package, and when he does, he gets the message: survey' is not a valid package -- installed < 2.0.0? When I run the library() command, I get (see below): Anything that is listed as ** No title available (pre-2.0.0 install?) **

"make check" is failing on reg-test3.R with a message that survival was built with an older version of R. (On my Ubuntu 32 bit and Ubuntu 64 bit machines).
