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 trouble with this: as.Date("Sep-1981", format="%b-%Y") Returns "NA" >From documentation for strftime '%b' Abbreviated month name in the current locale. (Also matches full name on input.) '%Y' Year with century. What am I doing wrong? cheers Worik [[alternative HTML version deleted]]

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 =

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 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

Dear all I tried finding a package for event studies but unfortunately without success. Does anyone know which package suits best for such an analysis? Thank you in advance. Regards [[alternative HTML version deleted]]

Friends, I have a POSIXct vector "located" in EST timezone. When I plot against it here in PST, the time axis is shifted 3 hours back in time. IOW, plot adjusts for time zone difference. Now that's really great, if that's what one wants. However, I want time axis to use actual times in object (without any shift). For example: n <- 360 y <- rnorm(n) t <- seq(from =

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) =

Dear Lister, Is there an interface in R with SQL server that allows me to append records to table in the DB? Might I do that using RODBC? Thanks a lot. -- WenSui Liu A lousy statistician who happens to know a little programming (http://spaces.msn.com/statcompute/blog)

Max & Friends, I've run into a problem with odfWeave 0.7.5 running under R 2.7.1 (Windows XP, SP2) doing some monthly production reports. Under 2.7.1 I'm getting various parsing errors after Sweaving starts, e.g.: Sweaving content.Rnw Writing to file content_1.xml Processing code chunks ... Error in parse(text = cmd) : unexpected input in "" > Above case works

I am new to R and I'd like to use the randomForest package for my thesis (identifying important variables for more detailed analysis with other software). I have found extremely well written and helpful information on the usage of R. Unfortunately it seems to be very difficult to find similarly detailed tutorials for randomForest, and I just can't get it work with the information on

Hello All, I have data where each feature data point is a vector, and my distance measurement is a weighted dot product between vectors. I would like to use R to perform a cluster analysis on this data. Does one of the R cluster analysis routines provide for a user provided distance function?

I was wondering if it would make sense to change the default behavior of the following: summary(15555L) ## Min. 1st Qu. Median Mean 3rd Qu.

Hi, I have an R script which is time consuming because it has two nested loops in it of at least 5000 iterations each, I have tried to use the multicore package but id doesn't seem to improve the elapsed time of the script(a shorter script for example) and I can't use the mcapply because of technical reasons. I was wondering how can I make my script use more cores and memory because I am
