useR's, I want to be able to rotate a matrix 90 degrees, clockwise. For example, > mat [,1] [,2] [,3] [,1] 1 2 1 [,2] 3 2 6 [,3] 4 5 3 I want to rotate it, so that it looks like this... [,1] [,2] [,3] [,1] 4 3 1 [,2] 5 2 2 [,3] 3 6 1 Does anyone know a quick and straightforward way to do this? Thanks in advance. -- View

Hi, I would like to access a local mysql database. In python using the sqlite3 library it is quite straightforward. I just have to pass the path to the sqlite-file; sqlite3.connect('.../xy.sqlite') Is there something similar in R (or specifically in the RMySQL package)? It seems like I have to use the MySQL function in the RMySQL package in order to ... "initializes a MySQL

Hi all, I'd like to be able to write JIT-compiled code to a Windows DLL. I have no idea where to start though. Does LLVM already offer some support for this? Or would it be straightforward to write my own DLL writer (no advanced features needed)? Or maybe I could use an external linker? All help highly appreciated!

Hi all, I'm usually comfortable using the *apply functions for vectorizing loops in R. However, my particular problem now is using it in a sequential operation, which uses values evaluated in an offset of the loop vector. Here is my example using a for loop approach: dat <- data.frame(year=rep(1970:1980,each=365),yday=1:365) dat$value <-

Hello, I imagine that I'm missing something straightforward, but a run thru the help files didn't turn up an answer. I noticed while formatting some figures for publication that text enclosed in expression() and used for a title displays differently than a string, regardless of the par options. On both postscript() and x11() devices, the regular text is heavier than the expression text.

I'm writing a php script to dial numbers and connect them to a conference. This is fairly straightforward: Action: originate Channel: Local/conf@default Context: default Exten: $extension Priority: 1 This is pretty straightforward. However, the script then loads the list of members in the conference (using the meetme list ... command). For local extensions this works fine - the list of

OK, I can do Debian and Ubuntu installs that don't use grub (and don't even install it) and instead only use extlinux. The extlinux configuration gets automatically updated during kernel upgrades, changes to extlinux configuration in /etc, and so forth. Is there anyway to do this in a straightforward (or semi straightforward) way in a modern RedHat derivative? On old legacy installs that

Dear list, i have a quick and (hopefully) straightforward question regarding the plot-function after running aov. if i plot an equation like this: plot(dataSubjects~factorA, data=mydata) R gives me the boxplots for this particular factor A. my model, however contains several factors. is there a straightforward way to plot barplots for a specific factor with the constraint that those values

Dear all, I would like to run a simple regression model y~x1+x2+x3+... The problem is that I have a lot of independent variables (xi) -- around one hundred -- and that some of them are categorical with a lot of categories (like, for example, ZIP code). One straightforward way would be to (a) transform all categorical variables into 1/0 dummies and (b) enter all the variables into an lm model.

Does anyone have a suggestion on how to handle this? For example, if I have a list of numbers that I want to go out a certain sip channel and another that I want to go out the dahdi device, is there a way to do this? None of the numbers will fit into a pattern, so just plain pattern matching won't do. The most straightforward way would be to just define explicit patterns. Obviously that

Why does R need the concept of "Vector"? In my opinion, it is a useless and confusing concept. A vector is simply a special case of a matrix whose row or column number is equal to 1. When I take submatrix from one matrix and if row or column number is 1, R will automatically convert it into a vector. It is very straightforward that a submatrix of a matrix should be a matrix. In

Dear r-helpers, Does anyone have a straightforward example of putting together three unrelated (expect for a common y-axis) xyplot() figures in what would be in base graphics a par(mfrow = c(1, 3)) arrangement? _____________________________ Professor Michael Kubovy University of Virginia Department of Psychology USPS: P.O.Box 400400 Charlottesville, VA 22904-4400 Parcels: Room 102

Hi, I am curious about whether there exist thread-safe functions in `Rinternals.h`. I know that R is single-threaded designed, but for the simple and straightforward functions like `DATAPTR` and `INTEGER_GET_REGION`, are these functions safe to call in a multi-thread environment? Best, Jiefei [[alternative HTML version deleted]]

Hello DWARF fans, I've just posted a set of four refactoring patches for DebugInfo/DWARF, which move in the direction of handling DWARF v4 or v5 type units and compile units more coherently. In DWARF v4, type units and compile units are strictly segregated into the .debug_types and .debug_info sections, respectively. This division was pretty ingrained into how DebugInfo/DWARF handled the

Anyone know if it would be straightforward to extract this information from Puppet, probably in a custom function: The classes included as a result of the client''s parsed configuration - or - Am I in class X as a result of my parsed configuration? I''m thinking it would result in a more elegant manifest if classes X and Y behaved differently if they were both included compared

I have a dataset of about 10^6 rows, each consisting of a timestamp, several factors, a string, some integers, and some floats. I'd like to graph this data in various ways, including straightforward ones (how many events per week over the past year for each of 4 values of some factor), some less straightforward. I've managed to do this by brute force, but I'd like to learn how to do
