similar to: filling area under a function line

Hola! It is somewhat inconvenient to use plot.function, when add=TRUE. The following (miniscule) change makes it behave better: plot.function <- function (fn, from , to, xlim = NULL, ...) { if (!is.null(xlim)) { if (missing(from)) from <- xlim[1] if (missing(to)) to <- xlim[2] } curve(fn, from, to, xlim = xlim, ...) } The only

I am sure it is just me not understanding how R works, but could somebody explain why curve(cos(x)) works and curve(expression(cos(x)) does not? I have done some investigating and here is what I found. If I comment out the line of curve indicated below, both calls work fine. function (expr, from, to, n = 101, add = FALSE, type = "l", ylab = NULL, log = NULL, xlim =

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Symptoms: curve with log x axis gets the wrong x limits (in 2.6.1, I believe introduced in this version). Credit goes to Mike McCoy for detecting the problem. Demonstration: x = 1:5 plot(x,5*exp(-x),xlim=c(0.1,1000),log="x") xvec = 10^seq(-1,3,length=100) lines(xvec,5*exp(-xvec)) curve(5*exp(-x),add=TRUE,col=2,lwd=3) I believe

Hi All, I have been able to modify the x-axis to start at zero by adding xlow and xhigh parameters; that was pretty simple. I have been unable to find the location of the code that would turn off the information weighting of the box size (I have smaller randomized trials getting less weight than a much larger non-randomized trial). The function is forestplot() from rmeta. Thanks for any

Hi, I make a graphic using xyplot, it is very good. xyplot((ocorrencia/isca)~frag|especie) But I need to plot a curve for each especie's plot. I try to use panel.abline and others panel., but I dont succeed. I need to plot the function exp(a+b*x+c*x^2)/1+exp(a+b*x+c*x^2), a b and c are different for each especie. Normally I use the curve function to add a curve in a points

I recently began hacking around with my first LLVM pass. The big picture is that I would like to insert function calls for each instruction type, and pass some parameters based on the instruction type. Then I will link the output to some C file that implements those functions. Things were going well until I started trying to make function calls with a pointer as a parameter. For example, I would

Hello, Here's an example that renders correctly using Rd2txt / Rd2latex / R CMD Rd2pdf, but has problems under Rd2HTML: \name{foo} \title{foo} \section{foo}{ This should be on a separate paragraph This should be on a separate paragraph This should be on a separate paragraph \Sexpr[stage=render,results=rd]{ paste( rep('Sexpr: This should be on a separate

Hi all, I am trying to use \Sexpr{} within \examples{} in the manual, and it all works fine, except that I get an error and then a NOTE from R CMD check when it checks for long lines in the manual. The long line check calls `Rd2txt` with fragment = TRUE, because it only checks the \usage{} and \examples{} sections, but fragment = TRUE does not evaluate \Sexpr{}, and then an unevaluated \Sexpr{}

Hi, I'm having a little issue with \Sexpr{bla} relating to the number of digits it is using to print its output. I understand that what \Sexpr{bla} does is parsing 'bla' inside R and then returns it coerced into a character string. The problem I'm having is that I'm losing control over the number of digits it's using to print it's output. For example, let's take:

I have come across an apparent bug in the operation of Sweave. If I load the package R2HTML then execution of \Sexpr{} in an *.Rnw file no longer works. The \Sexpr{} code is simply written to the *.tex file. Below are my *.Rnw file, commands, and output. The Sweave file, Sweave-test-1_short.Rnw: % -*- mode: noweb; noweb-default-code-mode: R-mode; -*- \documentclass{article} \title{A Test

Dear R useRs, I have a problem with nls.lm function of minpackl.lm package. I need to fit the Van Genuchten Model to a set of data of Theta and hydraulic conductivity with nls.lm function of minpack.lm package. For the first fit, the parameter estimates keep changing even after 1000 iterations (Th) and I have a following error message for fit of hydraulic conductivity (k); Reason for

Dear List, First off, my deepest gratitude to the Sweave developers: this tool has improved my quality greatly. A question in my work I use \Sexpr{} statements scalar values and the xtable package for all manner of tables. What I'd like to do is to use a vector inline, rather than a whole separate table. Something like: %%%%%%%%%%%%%%%% begin code % Latex junk % Sweave block:

I would like to create \examples{} in the manual dynamically, and while it is possible to do this with a \Sexpr at the top level, R CMD check issues a warning for it. (See below.) Is it intentional that \Sexpr is not allowed at the top level? The Rd grammar allows this, but R CMD check does not. Is there any other way to generate/modify the \examples{} section dynamically? Thanks, Gabor In

Hi: I am trying to create a dynamic latex table using \Sexpr{} but it's not evaluating it. I also tried the example below without Sweave and also fails. I have also copied the Sweave.sty to my working directory but nothing seems to work. Do I need to have certain package in order to run \Sexpr{}? \documentclass[a4paper]{article} \usepackage{C:/R/R-2.8.1/share/texmf/Sweave} \begin{document}

Hi, I want 3 digits printed even if the last one is zero with \Sexpr{} For example: > ghg.06[12] [1] 0.2501008 I want: 0.250 What I've tried: \Sexpr{round(ghg.06[12],3)} 0.25 \Sexpr{format(ghg.06[12])} % set options(digits=3) in earlier rnw chunk 0.25 \Sexpr{round(ghg.06[12],4} %but I want 3 not 4 digits 0.2501 Thanks in advance.
