Parametrized Vignettest in R packages
Hello, I have a package which includes some parameterized r-markdown report which I would also like to build as package vignettes. Is there a way to run the parameterized vignette creation with the package build or package check? Thank you -- Witold Eryk Wolski

MCLUST Covariance Parameterization.
Hello all (especially MCLUS users). I'm trying to make use of the MCLUST package by C. Fraley and A. Raftery. My problem is trying to figure out how the (model) identifier (e.g, EII, VII, VVI, etc.) relates to the covariance matrix. The parameterization of the covariance matrix makes use of the method of decomposition in Banfield and Rraftery (1993) and Fraley and Raftery (2002) where Sigma_k = lambda_k*D_k*A_k*D_k^' where Sigma_k is the covariance matrix for the kth (k=1,...,G), lambda_k is the kth groups constant of proportionality, D_k...

parameterization of factor in R
Hi all, I encountered this problem with parameterization in R: I have two factors in a regression. how about if I want to set constraint so that for each factor, the sum of their coefficients equals to zero(instead of choosing a reference category)? for example, I have factor(variable) A(with three categories) and factor(variable) B(with 4 categories),...

Parameterization of Inverse Wishart distribution available in MCMCpack and bayesm libraries
Hello Everyone Both the MCMCpack and the bayesm libraries allow us to make draws from the Inverse Wishart distribution. But I wanted to find out how exactly is the Inverse Wishart distribution parameterized in these libraries. The reason I ask is the following: Now its generally standard to express Inverse Wishart as IW(0.5 * DOF,0.5* Scale). (DOF-> Degree of freedom, Scale -> Scale

How to ask for *fixed* number of distributions under parameterized Gaussian mixture model.
Dear R users: I am wondering how to ask for *fixed* number of distributions under parameterized Gaussian mixture model. I know that em() and some related functions can predict the parameterized Gaussian mixture model. However, there seems no parameter to decide number of distributions to be mixed (if we known the value in advance). That is, assume I know the (mixed)data is from 3 different

parameterization of glm nested design
Dear R community, I am new to R, a reforming SAS user :) I am running R 2.10.1 on a Windows XP machine. I would like to write linear functions of my coefficient parameter estimates from a glm, but am having a difficult time understanding the parameterization R uses. In the toy example below I am running a glm on binomial data, with clones and lines within clones as fixed effects, each with 6 replicates. I cannot figure out the algorithm R uses for determining which combination of levels is used as the reference. Crawley, in the chapter on Statistic...

lme parameterization question
Hi, I am trying to parameterize the following mixed model (following Piepho and Ogutu 2002), to test for a trend over time, using multiple sites: y[ij]=mu+b[j]+a[i]+w[j]*(beta +t[i])+c[ij] where: y[ij]= a response variable at site i and year j mu = fixed intercept Beta=fixed slope w[j]=constant representing the jth year (covariate) b[j]=random effect of jth year, iid N(0,sigma2[b]) a[i]=random

Ruby DSL parameterized classes and defaults
I''ve been reading the Docs on this, and its not very clear. I want to have a parameterized class that takes arrays and objects as parameters. I''m using puppet 2.6.16. I define a hostclass like this: hostclass :test, :arguments => { :param1 => "blah" } do end I call from Puppet DSL: class {"test": } I get this as an error: err: Could not

Parameterized ActiveRecord Associations: Any such thing?
Hi list, how are ya? So, my current project is just begging for the ability to have parameterized associations in my ActiveRecord classes. Basically I need something that is a cross between named scopes and standard associations (has_many specifically). I''m wondering if such a thing exists or, if not, if anyone else has an elegant, equivalent solution? Example: class Sprocket <

parameterization of gnls model
...odel I'd like to fit: th=eh*((1+theta/thetaref)/(theta/thetaref))^(1/n), where th=true height (dependent variable); eh=estimated height (independent variable); theta is local incidence angle (independent variable); thetaref is fixed; n is the parameter to be estimated. My question is: is this parameterization efficient for gnls()? I've gotten reasonable results by changing the control settings, but also lots of warning messages. Thanks, Alan Swanson [[alternative HTML version deleted]]

Model parameterization / Factor Levels
...I'm looking for some hint about how to deal with the following situation: Response = Y Factor A = levels: 0, 1 Factor B = levels: 0, 1 Factor C = levels: 1,2,3,4 Model: Logistic 3-parms. where th1~1+A+C, th2~1+C; th3~1 For 'simplicity' (for me) I'm using the SAS contrast parameterization. The output looks like Beta p-value th1.(Intercept) 550 <0.000 th1.A1 -15 <0.000 th1.B1 5 <0.032 th1.C1 -12 <0.001 th1.C2 -5 0.022 th1.C3 -3 0.222 th2.(Intercept) ...... ......etc if we look at the results, we may conclude that level 3 for Factor C is not statiscally sig...

Problems using NLS in conjunction with non-parameteric bootstrapping
Hello, I have been successfully using nls to fit a non-linear, self-limiting function to several sets of data collected in 2010 (example found below). To generate confidence intervals for parameter estimates, I've been attempting to bootstrap my sample. Unfortunately, I have meet with singularity gradients and failures to converge. I have altered maxiter and minFactor statements, used

parameterized class precedences
Hello, I want to access variable of a parameterized class but it fails with "class has not been evaluated". Tried to evaluate it first adding stages and requires, but still same. I''ll explain better with an example: stage { pre: before => Stage[main] } class directory($path) { file { $path: ensure => directory, } } class directory::subdirectory { file {

Storing large BLOBs in the database with ActiveRecord
I have a model called Product with an attribute called file of type :binary (DB BLOB). If I do product.save (where product is an instance of my Product model), here is SQL statement that the mysql adapter for Ruby will do: INSERT INTO `PRODUCT` COLUMNS(NAME, PRICE, FILE) VALUES(''PROD1'', 4.56, X''00DEF033423023220'') All is hunky dory for as long as my BLOB is

using optimize with two unknowns, e.g. to parameterize a distribution with given confidence interval
Hi, I would like to write a function that finds parameters of a log-normal distribution with a 1-alpha CI of (x_lcl, x_ucl): However, I don't know how to optimize for the two unknown parameters. Here is my unsuccessful attempt to find a lognormal distribution with a 90%CI of 1,20: prior <- function(x_lcl, x_ucl, alpha, mean, var) { a <- (plnorm(x_lcl, mean, var) - (alpha/2))^2 b

Parameterized Samples Withdrawn
Although the parameterized samples have allowed people to get a firewall up and running quickly, they have unfortunately set the wrong level of expectation among those who have used them. I am therefore withdrawing support for the samples and I am recommending that they not be used in new Shorewall installations. -Tom -- Tom Eastep \ Shorewall - iptables made easy AIM: tmeastep \

Parametrized Vignettest in R packages
Hello, Thank you for the questions as well as remaining me of the default parameters in the yaml session. Indeed this seems to be the solution. But how would I assign package data as a default parameter? So originally I thought to render the markdown with : <code> data(sample_analysis) data(skylineconfig) x <- rmarkdown::render("report.Rmd", output_format =
