Dear all, Is there a way to force R CMD INSTALL to ignore ~/.Rprofile and similar? I presume it sources these startup files for a reason, but I've found that it can cause confusion or problems. In particular, my ~/.Rprofile loads a few packages which I very frequently use, but this stops me from installing new versions of their dependencies; viz. $ R CMD INSTALL tractor.base * installing to

Dear all, For an open-source project that I'm working on (1), which uses R for all its heavy lifting but includes a wrapper shell script, I was hoping to find a way to capture all warnings (and, in fact, errors too), and handle them in my own way. I realise I can do this for a single expression using something like: > f <- function(w) print(w$message) >

Dear all, I have a simple front-end program which uses the APIs described in section 8 of "Writing R Extensions" to deviate from the standard R behaviour in fairly minor ways. However, I'm having some difficulty getting it to link reliably across different platforms. R CMD LINK seemed like it would help, but I've had difficulty finding many real-world examples online. I've

Dear R-list members, I have a problem with translating a mathematica script into R. The whole script is at the end of the email (with initial values for easy reproduction) and can be pasted directly into R. The problematic part (which is included below of course) is <--- Original Mathematica ---> (* p_svbar *) UiA = Ni (Dsi - 2Di A + A^2)/2; UiiA = Nii (Dsii - 2Dii A + A^2)/2; psvbar =

Hi list, I have a problem with Mongrel which is really bugging me. I would really appreciate any help that anyone can provide to help me in solving this problem. 1. My setup: Apache front_end with mod_proxy_balancer in front of 4 mongrel/rails instances of my application. Rails 1.2.5 Ruby 1.8.6 Mongrel 1.1.1 2. I noticed that the CPU consumption on my server was 100% being consumed by ruby so I

I'm writing a pass that looks at the operands of certain non-commutable instructions and swaps a couple of them if certain conditions exist (a register bank conflict in the instruction). If the conflict exists, I build a new instruction which has the 2nd and 3rd operands swapped (using BuildMI). Then I want to get rid of the original instruction. I had done some searching and found that

Hi I have a rather strange problem with mongrel and I would be grateful if anyone could assist me with resolving. I have an application running mongrel 1.1.1 and rails 1.2.5 with ruby 1.8.6. It was all working fine and starting as expected. But I did a server reboot once and mongrel has refused to start up since. I get the following error:

Hello, I'm having a problem concerning r-binding datasets. I have six datasets, from six different plates, and two different days. I want to combine these datasets together for analysis. Datasets from day 2, have all the same columns than datasets from day 1. However in addition, there are few columns more in day 2. Thus, using rbind for this, results a error, because the objects are not the

I just noticed that read.table() and type.convert() interpret the string "i" as a missing value of type complex. > str(read.table(text=c("i\ni\ni\ni\n"))) 'data.frame': 4 obs. of 1 variable: $ V1: cplx NA NA NA ... > str(type.convert("i")) cplx NA If there are other strings in the column it makes the column character so most people

We tends to batch submitting packets during XDP_TX. This requires to kick virtqueue after a batch, we tried to do it through xdp_do_flush_map() which only makes sense for devmap not XDP_TX. So explicitly kick the virtqueue in this case. Reported-by: Kimitoshi Takahashi <ktaka at nii.ac.jp> Tested-by: Kimitoshi Takahashi <ktaka at nii.ac.jp> Cc: Daniel Borkmann <daniel at

Dear all, The version of readBin() in R-devel includes a use of match(), through `%in%`, which can affect its performance significantly. By using primitives instead of the rather expensive call to match(), I reduce the time spent inside readBin() by more than 30% in some of my code (part of the tractor.base package). A simple patch that does this is given below. This passes "make

Dear all, As of the current R alpha release, I'm seeing timezone-related warnings on installing any package (including the recommended ones), which I haven't seen before. For example, [~/Documents/Source/R-alpha]$ bin/R CMD INSTALL ~/git/tractor/lib/reportr * installing to library '/Users/jon/Documents/Source/R-alpha/library' * installing *source* package 'reportr' ...

Hello dear list, Using VMware I built a test setup of a server with dhcp, tftp and a http-server and several pxe-clients with EFI mode turned on. This setup worked, albeit with the exponential-like decay of IO rate I described earlier. The work-around of using HTTP works beautifully though. So it was time for the next step. Migrate this setup to our automated testing environment that runs

Dear all, There have been some recent major updates to the TractoR and RNiftyReg packages, which are available for medical image analysis applications. If you use R for these purposes, I hope you will find the updates useful. RNiftyReg is an image registration package, which provides a clean R-like interface to the NiftyReg library developed at University College London [1]. It is aimed at

Hi, when running a R-script like this: enable_magic() compute_stuff() disable_magic() the whole script is parsed into a single expression and then evaluated, whereas when using the interactive shell after each line entered, a REPL loop happens. Is there a way to make a script evaluation behave like this, because I need a single REPL iteration for every expression in the script. It doesn't

Dear all, The "tractor.base" package has recently been added to CRAN. This package provides functions to read, write, visualise and manipulate magnetic resonance images. The standard Analyze, NIfTI and DICOM file formats are supported (read-only for DICOM), and all metadata is stored with the image data internally. The code can be used to visualise image slices or maximum intensity

How similar should my rpm build machine be to my target deploy machines? Like, do you have to build on a multi-core machine if you plan to run on a multi-core machine? Or as long as the arch is the same, nothing else matters? johnn
