I think I understand tapply but i still can't figure out how to do the following. I have a dataframe where some of the column names are the same and i want to make a new dataframe where columns that have the same name are averaged by row. so, if the data frame, DF, was AAA BBB CCC AAA DDD 1 0 7 11 13 2 0 8 12 14 3 0 6 0 15

Hello everybody, I tried to measure the performance of the available drivers for windows as a HVM guest. I used the gplpv drivers 0.9.11-pre17, the PV drivers from Novell, and the drivers from Citrix XenSource with the XenServer 5. The Novell and gplpv drivers were more or less at the same speed, for both, network and disk performance. The disk performance was about 10MB/s reading and

I've been trying to build a bundle with the R-devel snapshot from yesterday. (Yes I know it is unstable and just tell me if I shouldn't be trying to do this yet.) It is failing with the message tar : /dev/rmt/0 : Permission denied It happens after "removing junk files" and just after the message "building dse_2000.9-1.tar.gz" It looks to be coming from the line in

I've compiled the 1.8.0 R on Solaris 2.9 and when trying to use plot command I get the Bus error and a core dump. Anybody experienced something like this? If yes, what should I patch? Janusz. [[alternative HTML version deleted]]

What is the Rd file alias and usage syntax for an S4 assignment method? I have been trying variations on \alias{TSdoc<-,default-method} \usage{ \S4method{TSdoc}{default}(x) <- value but so far I have not got it right according to various codoc, etc, checks.

I have a problem with my dynamically loaded code in R not finding pow_ii, which for some time I thought was because library f2c is not on my Sparcstation. However, I have now been experiencing the same problem in Linux, with all the proper libraries in place. My incomplete understanding of elf and shared libraries does not help, but when compiling a complete program I usually muddle through.

I think this is a bug, but perhap someone could confirm that it is not just me doing something stupid. (I vaguely recall something like this previously getting fixed in 1.7.0.)

I just tried to load r-devel (using rsync -r rsync.r-project.org::r-devel) and I get "operation not permitted" when I try ./configure. It appears the permissions and sticky bits are messed up again.

I've noticed that the arguments and result list of prcomp in the mva package (with 61.1) are not quite the same as in the Blue Book and in Splus. Is this intentional or can I change it?

I was hoping fatal: relocation error: symbol not found: pow_ii: referenced in .../dsefor.so would disappear in R 0.6x, but it has not. I believe this is suppose to come from the f2c lib, but I seem to need just a couple of routines: nm -u dsefor.so Undefined symbols from dsefor.so: .umul pow_dd pow_ii pow_ri For my own purposes I could compile with fortran but that makes it much

I sometimes wonder how difficult it would be to set up an email system, like the netlib@netlib.bell-labs.com facility for f2c, but for producing binary versions of packages. Has anyone every thought about this? I guess the main use would be for Windows, about which I know almost nothing, so I won't volunteer myself. Paul Gilbert

In an effort to encapsulate my dependence on class in order to deal with oldclass/class in Splus I defined the functions tfclass <- class "tfclass<-" <- function(x, value){ class(x) <- value ; x } and also the function classed <- function(x, cls) {class(x) <- cls; x} This last allows me to end a function definition with ... classed(somecalc,

The "data index" is mentioned in the R Extensions Writer guide as >> The subdirectory should contain a `00Index' file >> that describes the datasets available. I'm not sure what the official format is suppose to be, but given that it displays like an index, this has to be a very short description which I find somewhat inadequate. Some of my data sets are multivariate

pacf in devel seems by default to return a different number of lags than 1.7.1 for $pacf. I don't see any mention of this in the NEWS file, or any change in the documentation, so I suspect it is and error, though it may be an undocumented improvement. (Newbie question: How is the simplest way to display a function like pacf.default that is not exported from a namespace?) Paul

When I get a segmentation fault and core dump can I use gdb to examine the core file and get any useful information about why and where things went wrong? Do I need to compile R in a special way to do this? Obviously I'm a newbie at this. Details would be appreciated.

One of the functions I would like to clean out of my syskern package is a program to send mail. This is a common feature other programs (e.g. bug.report) may use so I would like it to be included in R/base. I will volunteer to do this as it looks like a fairly straightforward dissection of bug.report but I have some questions: Has anyone done this already? Is "mail" a good name or
