similar to: Displaying equations from .Rd files

I'm currently working on writing up some documentation for some of my code, but am having the darndest time coding in equations. For example, the equation in the following: \details{ Calculated the R Squared for observed endogenous variables in a structural equation model, as well as several other useful summary statistics about the error in thoe variables. R Squared values are

Hi, This is a problem about writing R documentation (R-exts 2.6). The command "\deqn" defined in "Rd.sty" is: \newcommand{\deqn}[2]{\[#1\]} which will put mathematical formulae in the "displaymath" environment; that means line breaks are not allowed (or will not be shown) in formulae, but sometimes we do need multiple lines of formulae. One solution is to write

The document R-exts contains the following example of using mathematics in R documentation. \deqn{p(x) = {\lambda^x\ \frac{e^{-\lambda}}{x!}} {p(x) = lambda^x exp(-lambda)/x!} There is a syntax error in there, but that's not my point. The problem is that using "R CMD Rd2dvi" I find that putting the alternate forms of the equation on top of each other doesn't work.

Hello all: I have written a few R scripts and am trying to turn them into a package for submission to CRAN. All of these scripts are R code only, no C or C++ or anything else. I'm working with R 2.0.1 running on a Windows XP machine. So far running ">rcmd install --build --docs=normal mypkge" seems to work (i.e., the library "mypkge" is installed in R\rw2001\library and

Dear list, I got an automatic email complaining than some of my packages didn't pass 'R CMD check' for R-2.10.0 alpha anymore. Both of them make use of the "cases" LaTeX environment. Inspecting the log outputs I got: LaTeX errors when creating PDF version. This typically indicates Rd problems. LaTeX errors found: ! Misplaced alignment tab

I have a long equation that I need to break in the R documentation of a package or it trails off the right hand side of the page. Here's the formula: \deqn{Cov(r_{ist}, r_{iuv})= [.5\rho_{ist}\rho_{iuv}(\rho_{isu}^2 + \rho_{isv}^2 + \rho_{itu}^2 + \rho_{itv}^2) + \rho_{isu}\rho_{itv}+ \rho_{isv}\rho_{itu}-(\rho_{ist}\rho_{isu}\rho_{isv} + \rho_{its}\rho_{itu}\rho_{itv}) +

Is there a way to display something like the quadratic equation, i.e. with a numerator and demonator on a plot? I think there is a way to create the equation in Latex, but wasn't sure if this format would translate to plotting. \begin{equation} ? x = \frac{b +/- sqrt(b^2 - 4*a*c)}{2*a} \end{equation} ? My searched turned up the following:

With help by Kurt and Martin I have written a short proposal for a new R doc source format that should be easier to parse using, e.g., perl. There should be especially a clearer distinction between text and keywords. Here we go, please make comments, corrections, etc. Best, Fritz ********************************************************** Conversion: ----------- A perl module providing

Hello, I would like to implement the feature request described here: https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=13287. I think this is a very worthwhile feature. However, I need just a little push in the right direction. When I added either a new command or change the old one to use eqnarray as proposed, the "\\" newline characters were not properly passed to latex - even

Hi all, I'm trying to estimate model parameters in R for a pretty simple system of equations, but I'm having trouble. Here is the system of equations (all derivatives): eqAlgae <- (u_Amax * C_A) * (1 - (Q_Amin / Q_A)) eqQuota <- (p_max * R_V) / (K_p + R_V) - ((Q_A-Q_Amin)*u_Amax) eqResource <- -C_A * (p_max * R_V) / (K_p + R_V) eqSystem <- list(C_A = eqAlgae, Q_A = eqQuota,

Hi, I am doing a small experiment to test if I can use MathJax ( official site: http://www.mathjax.org ) in R's html help pages (i.e. options(help_type='html')) and it seems working with some minor modifications. The screenshot (rendered by Firefox 4.0 beta and with STIX fonts) of the help page in html format with MathJax enabled is at the following url:

To R-helpers, R offers the polyroot function for solving mentioned equations iteratively. However, Dr Math and Mathworld (and other places) show in detail how to solve mentioned equations non-iteratively. Do implementations for R that are non-iterative and that solve mentioned equations exists? Regards, Mads Jeppe

Any recommendations on how I can get mathematical equations into my resulting html? (Besides using x^2^ type markup.) I figure I could parse out equation text from my main text before RedCloth ever sees it... and then maybe create png''s somehow from it, putting the links to them back into the main text before handing it over to RC. But I don''t know of a util that will generate

Hi, can anyone tell me if R can be used to rearrange very complicated equations in terms of one of the variables? I have: dx/dt = a*b*m*y*(1-x)-r*x and, having set: dy/dx = 0, need to rearrange in terms of x. The problem I have is that I don't know how to rearrange equations when the variables are not yet defined (I get messages warning me that x etc can't be found). I'm not sure

Hi, I would appreciate if someone could help me on track with this problem. I want to compute some parameters from a system of equations given a number of sample observations. The system looks like this: sum_i( A+b_i>0 & A+b_i>C+d_i) = x sum_i( C+d_i>0 & C+d_i>A+b_i) = y sum_i( exp(E+f_i) * ( A+b_i>0 & A+b_i>C+d_i) = z A, C, E are free variables while the other

Dear all, I am relatively new to R and have had some difficulty in understanding the user manual for a package that I have downloaded to evaluate non-linear simultaneous equations. The package is called systemfit. Does anyone have any experience of this package? What I am trying to do is solve a non linear simultaneous equations... Could anyone give me an example (please) of the code that

Dear all, I would like to estimate a system of regression equations of the following form: y1 = a1 + b1 x1 + b2x2 + e1 y2 = a2 + c1 y1 + c2 x2 + c3 x3 + e2 Specifically the dependent variable in Equation 1 appears as an independent variable in Equation 2. Additionally some independent variables that appear in Equation 1 are also included in Equation 2. I assume that I cannot estimate these two

Hi all, I have a system of 3 equations with many defined parameters and 3 variables I need to find solutions to. I actually know the solutions I'm aiming for (0.07,0.287,0.0061) but R tends to give me (0,0,0). I tried the "BB" package but don't really follow how to refine my solutions from that; these are wrong so far. Here's my code from trying that: > f<-function(x){

Hello. I need to view some docx files that embed equations. I installed wordviewer, then FileformatConverters in wine 1.5.3. Both install ok, and I can view docx files, except that the equations don't appear at all. Does anybody have a solution? Thanks! -- F. Delente
