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 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

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 =

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

I have been trying to read some data from an Excel workbook without success. The workbook is in .xls format and has multiple sheets, one with the sheet name Data, which is the sheet I wish to read from. One complication is that the header row of this sheet is comprised of dropdown boxes. I tried what I normally would do plus some variations. Here is the output. > require(RODBC) >

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 no experience with incorporating Fortran code and am probably doing something pretty stupid. I want to use the following Fortran subroutine (not written by me) in the file SSFcoef.f subroutine SSFcoef(nmax,nu,A,nrowA,ncolA) implicit double precision(a-h,o-z) implicit integer (i-n) integer l,i,nmax double precision nu,A(0:nmax,0:nmax) A(0,0) =

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 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, first, r-forge.r-project.org is filling a need and provides a great service to the community. Please read this thread as sincere feedback for making it even better, not as a complaint. I fully understand that r-forge is ran by limited resources and on a volunteer basis. I'll list some points about r-forge that I think could be improved/clarified. Not expecting anything, just sharing my

Here are some notes/observations I've done on my setup that works for me. Hopefully it will be added to some r-forge documentation/wiki.

Sorry to be completely off topic here, but I know there will be many list members who have an interest in and knowledge of hardware. We have for some time used Sun hardware for our departmental servers, most recently Sun Ultras of various specifications, running Solaris. We share some hardware with Mathematics as well. The applications we use are the usual suspects: R (obviously), S-PLUS, the

I want to do some recoding of variables: code Age into groups and recode a factor into a smaller number of levels. There are a couple of options for recode functions, in the car package and in memisc, and I think in gmisc. Does anyone have any opinions on the the easiest, most reliable approach for these problems? David Scott _________________________________________________________________
