Hello all, I have a data frame in R, imported from an excel file in Swedish. The original file contains several columns that have special characters, such as \¨{a}, \¨{o}, and so on. After import such special characters are represented in the data frame by "\\345", "\\366" etc (don't ask me why). For example, a word "Hårkan" becomes ''H\\345rkan".

Hello, all, I had problems with an extension to a classic optimization problem. The target is to minimize a quadratic form a'Ma with respect to vector b, where vector a=(b',-1)', i.e., a is the expand of b, and M is a symmetric matrix (positive definite if needed). One more constrain on b is b'b=1. I want to solve b given M. I tried but it seems impossible to find an analytic

Hello, there!   Basically my problem is very clear. I would like to take a (numerical) integration of a function f(x,y) which can be quite complex of x and y, over a disk (x-a)^2+(y-b)^2<= r^2 (with r constant). However, after some search in R, I just cannot find a function in R that suits my purpose. Function Integrate applies to one dimensional, and adaptIntegrate to rectangle. In my case, it

Hello everyone. I am in the process of writing a book in Latex with Texshop, on Mac. This book contains a lot of R code, hence the need to use Sweave. I was able to compile Rnw files, and to sync back and forth from the pdf to the source Rnw. My problem now is that the book is divided in Chapters, and every chapter is in its own Rnw file. I can compile them from the main one (book.Rnw) using the

Hi, I have a vector of strings (class character) with 6 elements (length 6). I call it 'names'. "Graham Chapman" "John Cleese" "Terry Gilliam" "Eric Idle" "Terry Jones" "Michael Palin" And I want to turn it into another vector of strings called 'shortnames' with the same length. The new vector should look like:

Hello all, I need to extract rows and columns from a data frame and put them in a matrix. In some cases, there are no rows in the data frame meeting the selection criteria. For those rows I want to put a row of 0's in the matrix. Here's my clumsy code: tab1.m1 <- matrix(0, nrow=2, ncol=4) tab1.m1[1,] <- ifelse(length(as.matrix(tab1[tab1$comp==the.comp & tab1$schlid==the.schl

I have two servers identified as `server-1 - 192.168.3.128` and `server-2 - 192.168.3.130`. I am setting up `capifony` for automatic deployment from server-1 to server-2 and this is what I have done so far: 1. In both servers I have created a user `deploy` without password since that's the user I will use for deployment. 2. In server-1 I setup a SSH keys by running the command:

Hello all, Sometimes I get to make an R code chunk (in Sweave) which is longer then the margins of the page. Is there a way to force it to "go to the next line" (in Sweave) once that happens? Here are two cases this happens in the resulting .tex file (one is a "hard" case, and the other is simpler) \begin{Schunk} \begin{Sinput} >

Hello, S-plus and R helpers,(sorry for cross-post) I wrote some simple C code for one likelihood to be optimized (using optim(MASS)). I use same function, same data, same starting points and same DLL in R and S-plus for comparison. (I compiled it with 'Rcmd SHLIB likelihood.c' and the header files of it include only R.h and math.h). While it works quite fine in S-plus, it forever returns

Hi R useRs: How can I generate a random sample from Maxwell Distribution in C language? Since I know the function rmaxwell {VGAM}, I tried the function r2c {r2c}. But I still cannot find the source code. Thanks for your kind help. RegaRds, 2010-03-12 Randel [[alternative HTML version deleted]]

Hi Folks, I'm surprised, but I didn't find this question addressed anywhere. I'd like to generate a LaTeX caption with R code. I've tried the code below, but I get the following TeX error: ! Argument of \@caption has an extra }. <inserted text> \par l.21 } Any thoughts? Perhaps I'll have to write the "\caption{}" text with R? thanks!

Hi (Duncan?), The other day I noticed some characters will cause errors in R CMD CHECK because of parse_Rd(), and AFAIK, these chars include '%', '{' and '}'. For example, note the comments in the example section: %~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~% \name{testfun} \Rdversion{1.1} \alias{testfun} \title{ A Test } \description{ A test } \usage{ testfun() } \value{ NULL }
