How do you prove usefulness of a feature? Do you have an example of a feature that has been added after proving to be useful in the package space first?

I think you are confusing package and function here. Plus some of the R Core packages, that you mention, contain functions that should probably be replaced by functions with better implementation from packages on CRAN.

Hi list, I've installed samba 2.2.3a on my Linux box. I have to join into an NT4 domain and all works fine. I've got only a question: Now I'm able to mount the NT share with the command: mount -t smbfs -o username=morgan,password=morgan //SERVERNT/DISC /mnt and it works only if I am root. Is there any possibility of mounting it automatically on boot? I've tough about /etc/fstab but

Hi All, I was looking for a function to find a small matrix inside a larger matrix in R similar to the one described in the following link: https://www.mathworks.com/matlabcentral/answers/194708-index-a-small-matrix-in-a-larger-matrix I couldn't find anything. The above function can be seen as a "generalisation" of the "which" function as well as the function described

No, I just think 15 years or so is more than enough time to have addressed the issue.

Hi, It sometimes happens that some packages get included to R like for example the parallel package. I was wondering if there is a process to decide whether or not to include a package in the core implementation of R? For example, why not include the Rcpp package, which became for a lot of user the main tool to extend R? What is our view on the (not so well known) dotCall64 package which is an

Notice also Additionally, since you're implementing a "mean" function you are testing against R's mean, you might want to consider that R uses a two-pass calculation[1] to reduce floating

It?s rather difficult. For example, the base R Kendall tau is written with the naive O(n^2). The much faster O(n log n) implementation was programmed and is in the pcaPP package. When I say much faster, I mean that my implementation in Excel VBA was faster than R for 10,000 or so pairs. R-Core decided not to implement that code, and instead made a note about the faster implementation living in

Hi, Hope you are well. I was wondering if there is a function at C level that is equivalent to mtcars$carb or .subset2(mtcars, "carb"). If I have the index of the column then the answer would be VECTOR_ELT(df, asInteger(idx)) but I was wondering if there is a way to do it directly from the name of the column without having to loop over columns names to find the index? Thank you Best

Hi, I am wondering if the below is possible? Let's assume I have the following expression: 1:10 < 5 Is there a way at the R C API level to only evaluate the 5th element (i.e 5 < 5) instead of evaluating the whole expression and then select the 5th element in the logical vector? Thank you Best regards Morgan [[alternative HTML version deleted]]

So i updated rails and this is now what i''m getting. i tried reinstalling rails and it didn''t help. it''s installed. this is driving me nuts. i''m at rails 2.3.5 and ruby 1.8.7 Missing the Rails gem. Please `gem install -v= rails`, update your RAILS_GEM_VERSION setting in config/environment.rb for the Rails version you do have installed, or comment out

Hi, Using the R C PAI, is there a way to convert to convert STRSXP or INTSXP to factor. The idea would be to do in C something similar to the "factor" function (example below): > letters[1:5] # [1] "a" "b" "c" "d" "e" > factor(letters[1:5]) # [1] a b c d e # Levels: a b c d e There is the function setAttrib the levels of a SXP

Hi, Is there a way to resize a matrix defined as follows: SEXP a = PROTECT(allocMatrix(INTSXP, 10, 2)); int *pa = INTEGER(a) To row = 5 and col = 1 or do I have to allocate a second matrix "b" with pointer *pb and do a "for" loop to transfer the value of a to b?

Hi, I installed libvirt on CentOS 6 today, only to find I could create the volume, create the VM, but could not assign the interface to a distributed port group. I then downloaded the latest source, compiled, and it looks to be the same...unless its under a command I'm not recognizing? Does anybody have the great tip that is going to set me free? I hope? Everything we use is on the

As the original coder (in mid 1970s) of BFGS, CG and Nelder-Mead in optim(), I've been pushing for some time for their deprecation. They aren't "bad", but we have better tools, and they are in CRAN packages. Similarly, I believe other optimization tools in the core (optim::L-BFGS-B, nlm, nlminb) can and should be moved to packages (there are already 2 versions at least of LBFGS
