I have a problem with expressions. I am trying to create a title where the parameter of interest is displayed as a Greek character. Which parameter is being considered is stored in a character variable. As an example, if I have param <- "alpha" and then do plot(0, 0, main = bquote(Parameter==.(param))) then in the title I get "Parameter = alpha", whereas I want the

I am investigating some approaches to reproducible research. I need in the end to produce .html or .doc or .docx. I have used hwriter in the past but have had some problems with verbatim output from R. Tables are also not particularly convenient. I am interested in R2HTML and R2wd in particular, and possibly odfWeave. Does anyone have sample documents using any of these approaches which

I have been struggling trying to write some code to produce all combinations subject to some restrictions. I thought someone might have some bright ideas. I have 11 values which fall into 5 groups. I want all combinations of 2,3, and 4 values where each value must be from a different group. The numbers in the groups are different. Here is a definition of the groups: groups <- list(gp1 =

Hi, I am new to R and I'm looking to perform some method comparison analysis and would be grateful for some help regarding package installation. There is a package 'MethComp' that I want to use (http://staff.pubhealth.ku.dk/~bxc/MethComp/Courses/Sthm.2007/.) Unfortunately I am unable to install it. I have tried numerous approaches but to no avail. this is the first time I have tried to

I have used xlsReadWrite to read data from an Excel spreadsheet. I had a problem with converting times of the day so that I could create POSIXct date-time objects. I was wondering if there was a better solution. Excel stores times of the day as fractions of a day so I wrote a function to convert the fraction to a number of seconds, extract the hours, minutes and seconds and output it in ISO

I have a client running Microsoft SQL Server. I am interested in ways of accessing data from this server using R. I would welcome any information about how this can be done. I have a reasonable grasp of SQL and have experience with MySQL and RODBC but don't know anything much about Microsoft SQL Server.

I have a client who uses Stata 11. Can anyone advise me on ways of transferring data from this version of Stata to R? Reading the documentation for read.dta in package foreign it seems it only allows for versions up to Stata 10. I don't know Stata at all but a bit of poking around on their website led me to believe Stata 11 couldn't write in Stata 10 format. However Stata 11 can

I have been playing around with producing tables using xtable and the type = "html" argument when printing. For example, if xtbl is the output of a dataframe which has been run through xtable, using the command: print(xtbl, type = "html", html.table.attributes = "border = '1', align = 'center'") I would be interested to see other examples of

This I am sure is a very easy question, but I can't seem to find the answer.

I was playing with Dovecot 1.1 full text indexing through Squat in late October, which was working pretty well. I wanted to ask about this behavior I had: When an email arrives in INBOX using procmail (which delivers to my Maildirs), and I see it in Dovecot, when I next do a search (IMAP SEARCH TEXT) of that folder, the search takes a long time. Successive searches are lickety-split. My

I am writing a package for a company for its internal use only. What is an appropriate license statement for the DESCRIPTION file? I would like a statement which reflects the private and proprietary nature of the package, giving copyright to the writer and the company. I also don't want to violate the licensing of R and the packages I am using (RODBC, ggplot2, zoo). David Scott --

I am looking for a method of dealing with the modified Bessel function K_\nu(x) for large \nu. The besselK function implementation of this allows for dealing with large values of x by allowing for exponential scaling, but there is no facility for dealing with large \nu. What would work for me would be an lbesselK function in the manner of lgamma which returned the log of K_\nu(x) for large

Does anyone know how to link Rails'' routes into anonymous controller classes created at runtime (defined with their superclass as ActionController::Base)? I''m trying to create a plugin for all of my projects that dynamically creates an active_scaffold controller for each model. It would essentially be like a scaffold_all_models for active_scaffold. I believe the original

I would like to add some vertical lines to a lattice plot of histograms. What I am after is a lattice version of abline(v = 1234). The lattice histogram plot is just: histogram( ~ LTSE | approach, data = arrivals) Can anyone point me in the right direction for this?

Hi all, I apologize for this off-topic question but I need your help -- I know there are lots of experts here. As a lover and student of statistics, I am thinking of building a tree of various branches of statistics and keeping track of the greatest historical inventions/discoveries in statistics and the latest development of each branch. The goal is to understand in what context did the great

A naive question: what happened to the xlsReadWrite package? http://cran.r-project.org/web/packages/xlsReadWrite/ It says that it was removed from the CRAN repository. Are there any plans for it be available again? Thanks, Andrew [[alternative HTML version deleted]]

Hi, I have a problem with the metaplot-function in rmeta. After plotting a Forest Plot with "metaplot", no y-axis is shown for normal plots anymore. Does someone know, why this is and how I can solve it? Thank you in advance!
