Hi, When writing formulae in Rd files I use \leq to get a less-than-or-equal-to sign, as this is what the LaTeX references I consulted suggested. This works correctly for the PDF output (Rcmd Rd2dvi.sh --pdf), however when the Rd file is converted to text or html this command is converted to "<=q". A workaround is to use \le instead of \leq which works with my LaTeX distribution

Dear R Users, Is the p-value reported in a two-tailed binomial exact test in error or is it a feature? If it is a feature, could someone provide a reference for its two-tailed p-value computations? Using Blaker's (2000 - Canad. J. Statist 28: 783-798) approach,the p-value is the minimum of the two-tailed probabilities $P \left(Y\geq y_{obs}\right)$ and $P\left(Y\leq y_{obs}\right)$

Parametric polymorphism is different from subtype polymorphism; you can have one without the other. Parametric polymorphism just means that you can use type variables (like T) in the IR, which are later instantiated to

Hi! I''m trying to extend ActiveRecord''s find method (Rails 1.0, Ruby 1.8.2), but I recognize a strange behaviour of the "alias_method" call. I wrote a very simple script to explain my problem: ------------------------------------------------------ module ActiveRecordExtension def self.included(base) base.extend(ClassMethods) base.class_eval do

Hello everybody! I have problems with integrating my function. My primary function is a “survival function” of the following type: surviv <- exp(-k*x)/(1+exp(alpha*(x-tau))) I would like to integrate this function over a defined range and obtain a vector with all the values from integrate(surviv, 0, x) for x <- 1:N. I unfortunately obtain just a scalar value corresponding to the last

Hello, I'm fairly new to R and I can't work out how to produce a double inequality like (LaTeX) $0 \leq x \leq 1$ in the legend of a graph. If I try > legend(50, 0.1, legend = c(expression(0 <= x <= 1), c(2 <= x <= 3)), pch = c(1,1), col = c(2, 3)) then I get an error message "unexpected '<=' in ...". I've checked the help files for plotmath and

Hello, Thomas Stabla (statho3@web.de) has already sent this question to R-help, Wed, 12 Nov 2003 21:21:31 +0100, but we are not sure whether we should better post this mail to this audience than to R-help: --------------------------------------------------------------------- We are using S4-classes and want to force a validity check when an object is created. How can this be done, when an

Greetings, Sorry, the last message was sent by mistake! Here it is again: I encounter a strange problem computing some numerical integrals on [0,oo). Define $$ M_j(x)=exp(-jax) $$ where $a=0.08$. We want to compute the $L^2([0,\infty))$-inner products $$ A_{ij}:=(M_i,M_j)=\int_0^\infty M_i(x)M_j(x)dx $$ Analytically we have $$ A_{ij}=1/(a(i+j)). $$ In the code below we compute the matrix

Here's my translation of the Fibonacci example into OCaml: open Printf open Llvm let build_fib m = let fibf = define_function "fib" (function_type i32_type [| i32_type |]) m in let bb = builder_at_end (entry_block fibf) in let one = const_int i32_type 1 and two = const_int i32_type 2 in let argx = param fibf 0 in set_value_name "AnArg" argx; let

Hello, the last command (isGeneric) in following R-code (attached) produces different output, depending on wheter 1.8.0 alpha or 1.7.1 is used. Is that to be expected ?

Dear all, I have some trouble with special characters while building my R package. I tried to follow the usual LATEX format, but could not fix the problem: For instance, for "greater than or equal", I tried "\geq", but R says that this is an unknown macro. Could anyone direct me how to solve this issue? Best Ozgur ----- ************************************ Ozgur ASAR

I''m happy I''ve succeeded in creating Windows 2003 server guest VM on a xen machine. (if anybody interested in how to, refer to Xen Technical Note V07132006) My further question is: is there a way I can assign a null video device to Windows VM? I want win server keep working, but not its display (implemented on gnome) on console monitor all the time. Joon Woo

Hello, I am looking into description of surf.ls(spatial) and see under value $beta - the coefficients. When I use polynomial of degree 2 to fit surface I expect to get 4 coefficients: z = a_1 x^2 + a_2 xy + a_3 y^2 + a_4 What do beta really stand for and why do I get $beta vector of length 6? Thakns, Mark

Friends- I have taken a new job and will be moving at the end of March. The newspaper I currently work for is looking for someone to take my place. I have really enjoyed working here. It is a great environment with very nice people to work with. And the best part is you get to develop in Ruby and Rails, for everything! The paper is willing to accept applications from people who would
