Hi all, I am trying to create images in R suitable for journal publication. I'd like to make an image that is 3.6" wide and 5.08" length, and 1200 dpi. When I create a tiff file that is 800 dpi and 4x4", it works (although doesn't look good). But when I create a tiff that is the size and dpi I want, it doesn't work. I get the following error: Error in tiff(filename =

Hello, I have 2 servers I'm synchronizing using rsync, I have a situation where I : 1. rsync from rnd-dev2 to rnd-dev1 2. change the rsynched file on rnd-dev1 3. rsync from rnd-dev2 to rnd-dev1 again 4. File gets overridden on rnd-dev1 over though it has newer change time then file on rnd-dev2. here is the bug(?) reproduction: [root@rnd-dev1 test_rsync]# rsync --version rsync version

(Probably OT) Has anyone else noticed these flaky (new?) behaviors in Evo since the 5.2 upgrade: - REALLY slow saving messages from inbox to another folder - search capability separated by folder instead of overall (with no option for control) - failure to autocomplete email addresses for known contacts I think that's it. I was wondering if it was just me, or if others had noticed this.

Hi, I am trying to add additional columns to a forest plot using the meta package. The study information and subgroup analysis plotting is handled properly. For this output the data is ordered first by subgroup label (rnd.subgroup1 in the example) and second decreasing size of totals ('n' in the example). The proper ordering of this data is confirmed by the color coding (black and red in

I'm analyzing the basic blocks of MachineInstructions that LLVM generates for my TargetMachine to try to reconstruct high-level flow control. I misunderstood the isTerminator property of an instruction to mean that it had to be at the end of a basic block, but now I've seen blocks that end with a conditional branch followed by an unconditional branch. I'm sure this depends

Hi there, We are trying to compile a 64bit version of R (2.5.1) on HP-UX (B.11.23 U ia64), but are running into some problems. This is our configure step: ../configure --prefix=/rnd/homes/lfan/R251 --enable-R-shlib CC="cc" CFLAGS="+z +DD64" CXX="aCC" CXXFLAGS="-b -lxnet +z +DD64" FC="f90" FCFLAGS="+DD64" F77="f90"

Hi, I'm Sorry for any cross-posting. I've reviewed the archives and could not find an exact answer to my question below. I'm trying to generate very large sparse matrices (< 1% non-zero entries per row). I have a sparse matrix function below which works well until the row/col count exceeds 10,000. This is being run on a machine with 32G memory: sparse_matrix <-

To anyone who can help, I have two stupid questions, and one fairly intelligent question Stupid question (1): is there an R function to calculate a factorial of a number? That is...is there a function g(.) such that g(3) = 6, g(4) = 24, g(6) = 720, etc? Stupid question (2): how do you extract the estimated covariance matrix of the random effects in an lme object? Intelligent question

Hm. I assumed that JumpThreading would be the primary factor in optimizing code like this. Guess not. I'll need to look into SimplifyCFG to see what prevents it from doing the same thing to the other loop: https://godbolt.org/z/F6NjdG On Mon, Feb 3, 2020 at 3:09 PM Michael Kruse <llvmdev at meinersbur.de> wrote: > I assumed the LLVM-IR behind the godbolt link represented the C code

Hello, I have a C++ code for 2D random walks with traps and I want to convert it in a R code with its syntaxs, can anyone help??????? It's easy for me to adapt the body but I want help with the beginig (variable declaration) and th end exporting the output to a file ( like write.table() or sink() ) Thank you... #include <iostream> #include <math.h>#include

Hi, I recently ran into the problem that I needed a Siegel-Tukey test for equal variability based on ranks. Maybe there is a package that has it implemented, but I could not find it. So I programmed an R function to do it. The Siegel-Tukey test requires to recode the ranks so that they express variability rather than ascending order. This is essentially what the code further below does. After the

I am have a shorewall firewall and freeswan ipsec running on a redhat 8.0 Linux gateway machine. I have one working tunnel defined, all works well. I am not clear how to define mutiple concurrent tunnels. I can not add further interface entries as all the tunnels come in on ipsec0, do I still have mutiple zone definitions? some of the tunnels will be dynamic roadwarriors and as such would need a

Dear List As a fairly new R programmer I seem to have run into a strange problem - probably my inexperience with R After reading and merging successive files into a single data frame, I find that order does not sort the data as expected. I have multiple references in each file but each file refers to measurement data obtained at a different time. Here's the code library(reshape) #
