Does anyone know what could be causing the following error message on startup of R: Error in .addMethodFrom(def,argName[1],class[1],fromClass) : object "*tmp*" not found. I'm using R 1.7.0 and Windows 2000. This happened shortly after I installed 1.7.0. Once it occurs, R freezes. >From then on R will always freeze with this error message. I reinstalled 1.7.0 and it worked

What is a simple way to convert a factor into a matrix of dummy variables? fm<-lm(y~f) where f is a factor takes care of this in the estimation. I'd like to save the result of expanding f into a matrix for later use. Thanks. Charles -- Charles H.

II am translating some gauss code into R, and gauss has a matrix product function called the horizontal direct product (*~), which is some sort of variant on the Kronecker product. For example if x is 2x2 and y is 2x2 the horizontal direct product, z, of x and y is defined (in the Gauss manual) as: row 1 = x11*y11 x11*y12 x12*y11 x12*y12 row 2 = x21*y21 x21*y22 x22*y21 x22*y22 Or in R

Hi there Within sampleSelection, I'm trying to calculate the marginal effects for variables that are present in both the selection and outcome models. For example, age might have a positive effect on probability of selection, but then a negative effect on the outcome variable. i.e. Model<-selection(participation~age, frequency~age, ...) Documentation elsewhere describes one method for

A newbie question: I'm trying to decide whether to run a maximum likelihood estimation in R or Stata and am wondering if the R mle routine is reasonably robust. I'm fairly certain that, with this data, in Stata I would get a lot of complaints about non-concave functions and unproductive steps attempted, but would eventually have a successful ML estimate. I believe that, with the

I am trying to use the optimizing function genoud() with the snow package on a couple of i686 machines running Redhat Linux WS4 . I don't know anything about PVM or MPI, so I just followed the directions in snow and rgenoud for the simplest method and started a socket cluster. My function fn for genoud involves updating an input file for a separate numerical model with the latest parameter

I would rather use cleveland dot plots than bar charts to display my study results. I have not been able to find (or figure out) an R package that is capable of producing the publication quality dot charts Im looking for. I have either not been able to get error bars (lattice), cannot order the data display properly (latticeExtra), or cannot make adjustments to axes. Does anyone have a quick

Hello, I'm using optim to program a set of mle regression procedures for non-normal disturbances. This is for teaching and expository purposes only. I've successfully programmed the normal, generalized gamma, gamma, weibull, exponential, and lognormal regression functions. And optim returns reasonable answers for all of these compared with the identical optimization problems in STATA and

Hi, With the help of Dirk Eddelbuettel, I was able to fix a few little problems that prevented the rimage (0.5-7) package from working under (at least) R 2.8 or 2.9 and g++ 4.2 or 4.3. I have uploaded a new release, 0.5-8, that fixes these problems. It have attempted to contact the package's maintainer, Tomomi TAKASHINA <t.takashina at computer.org>, to no avail. Kurt Hornik

My problem is I have data with both categorial and numerical data, currently only the categorical number contains missing data, was wondering do I make a new dataframe containing only the categorical columns? How would you use Latent Class Model specifically poLCA to impute the missing data? http://www.sscnet.ucla.edu/polisci/faculty/lewis/pdf/poLCA-JSS-final.pdf The reason why I chose not to

Is there any way to echo comments from an R source file into an SWeave->LaTeX document? Example: # Npop is population total # Npoph0..Npoph2 are stratum totals # Npoph is vector of stratum totals Npop<-sum(to2000) Npoph0<-sum(to2000[bg==0]) Npoph1<-sum(to2000[bg==1]) Npoph2<-sum(to2000[bg==2]) Npoph<-c(Npoph0,Npoph1,Npoph2) In the final LaTeX document, I'd like the

Dirk Eddelbuettel and Albrecht Gephardt have created many Debian packages of R packages from CRAN and other archives. I wanted to install all these Debian packages on a machine running the Debian testing distribution. One way to do this is to search (using the apt-cache program) for all Debian package names that begin with 'r-', extract the package name, and concatenate all those names

Deal list, I have a data frame (birth) with mixed variables (numeric and alphanumeric). One variable "t1stvisit" was originally coded as numeric with values 1,2, and 3. After attaching the data frame, this is what I see when I use str(t1stvisit) $ t1stvisit: int 1 1 1 1 1 1 1 1 2 2 ... This is as expected. I then convert t1stvisit to a factor and to avoid creating a second

One of many scripts to produce 4 lattice plots on one page keeps throwing an error. I've tried manipulating the file to eliminate the error, but have not been able to do so. The error is: > source('bicarb.R') Error in source("bicarb.R") : bicarb.R:15:1: unexpected symbol 14: 15: hco33 ^ The 'h' is in column 0 so the caret would be column -1, but it's

Dear R users, About a year ago Deepayan offered a suggestion to incorporate error bars into a dotplot using the singer data as an example <<http://finzi.psych.upenn.edu/R/Rhelp02a/archive/63875.html>>. When I try to utilize this code with a grouping variable, I get an error stating that the subscripts argument is missing. I have tried to insert them in various ways, but cannot
