Hi, recently R CMD check --as-cran has noticed some more issues with package namespace imports with the recommended remedy to use importFrom() and friends. In my case, there was only a conflict restricted to some few imports, while I would prefer to still import all the non-conflicting objects, methods, and classes of the respective package namespace. So would it be possible to have some new

Hi, to speed up computations in our RobASt family of packages, we use interpolation on a grid of precomputed values which we save together with the interpolating functions (results of splinefun essentially) in sysdata.rda in the R folder of our pkg. After adding grids for some more models, this file has grown considerably, even after application of tools::resaveRdaFiles. At the moment we are at

Hi R-devels, latetely I reported having problems with understanding warnings issued by a devel version of R CMD check, which Brian Ripley in his reply https://stat.ethz.ch/pipermail/r-devel/2008-August/050493.html correctly attributed to my using an outdated version (July 29) --- you really have to be quick with updating these days! Having switched to a more recent version, R CMD check

This is a Request For Comment, also BCCed to 390 package maintainers of reverse dependencies of the Matrix package. Most users and package authors working with our 'Matrix' package will be using it for numerical computations, and so will be using "dMatrix" (d : double precision) matrix objects M, and indirectly, e.g., for M >= c will also use "lMatrix" (l:

Hi, I am translating some Gauss code to R. Gauss has an interesting way of handling constraints. Observe the following code snipplet: e1 = x[.,23] .eq 0; @ remove obs with Regular Hours = 0 @ e2 = x[.,12] .gt 1; @ remove obs with non-regular work status @ e3 = x[.,4] .lt 15; @ remove obs with agricultural and mining industry code (< 15)@ esum = e1 + e2 + e3; e = esum .gt 0; @

I have a data frame (df) with colums x, y and z. e.g. df <- data.frame(x = sample(4), y = sample(4), z = sample(4)) I can extract column z by: df$z or df[3] I can also extract columns x,y by: df[1:2] or by df[-3]. Is it possible to extract x,y columns in a "symbolic" fashion i.e. by equivalent of df[-z] (which is illegal) ??? Or alternativeley, is there an equivalent of

R-devel, I'm interested in looking at some examples of existing R packages that rely heavily on S4 classes to get a feel for varying styles and package organization techniques. Could you recommend any packages that might serve as a good starting point? Thanks in advance, Jeff

Dear R-devels, We have encountered a problem concerning a dead lock in the dependency graph: We have two packages A1 and A2 where A2 extends A1. We have one package vignette for both packages, but which should be included into package A1. So in the "suggests" field of the DESCRIPTION file of A1 we suggest A2 to be able to produce the vignette at build/install time. On the other hand

Hello, I want to know if there are some functions or packages to solve differential and integral equation using R. Thanks. Shao chunxuan. [[alternative HTML version deleted]]

Dear all, I am trying to use the function odfWeave. Unfortunately I cannot get beyond the folllowing error message: " Error in odfWeave("Example3.rnw", "Example3.odf") : Error unzipping odt file " Can anybody tell me, how to use this function? Thanks, Irina Ursachi.

Hello! I think there is a small bug in cmdline parsing for option usermap and groupmap. If you give multiple mappings to --usermap or --groupmap, only the first one is used. Example: rsync -a --usermap=userA:userB,userC:userD <src> <dst> -> Only the user mapping for userA to userB is used, the second mapping is ignored. The attached patch fixed the problem for me. Greetings

Hi, just a little wish : Could we have one (or maybe more) standardized optional tag(s) for package DESCRIPTION files to cover svn revision info? This would be very useful for bug reporting... I know that any developer is already free to append corresponding lines to DESCRIPTION files to do something of this sort --- e.g. lines like LastChangedDate: {$LastChangedDate: 2009-03-31 $}

The characteristic function is the inverse Fourier transform of the distribution function. The characteristic function of a normaly distributed random variable is exp(-t^2/2). x=seq(-2,2,length=100) fft(pnorm(x),inverse=T)/length(x) exp(-x^2/2) Why aren't the inverse fft and the mentioned function the same? Thanks for help, Thomas
