Dear r-devel, I have implemented a function to create color palettes with improved contrast and logical order, compared with the built-in ones: source("arni.colors.R") # code is given below barplot(rep(1,100), col=arni.colors(100), space=0, border=0, axes=F) par(mfrow=c(2,1)) # rainbow() has too much green... barplot(rep(1,50), col=rev(rainbow(50,end=0.7)), space=0, border=0, axes=F) barplot(rep(1,50), col=arni.colors(50), space=0, b...

...e only user who would appreciate if as.is=TRUE becomes the default at some point. So I am happy to hear that the help page now mentions that the as.is=TRUE is planned to be the default at some point in the future. Looking forward to the 4.0.0 official release - all positive changes!

...ke llvm to be installed. I did not give --with-llvmgccdir argument to configure. Because 3.0 doesn't come with llvmgcc source/binaries and I decided upon using the compatible version of dragon egg. 2. I made dragon egg, I updated the makefile of the same in the line "LLVM_CONFIG?=/home/arnie/llvm/llvm-install/bin/llvm-config" (llvm was installed inside llvm-install directory). It successfully produced the dragon egg .so file. Using this .so file I was able to compile simple c programs and manipulate them. 3. I tried to compile test-suite. I downloaded the test-suite into the...

...a good time to change the default to type.convert(as.is=TRUE), to align it with the new default in read.table and data.frame. I think many R >=4.0.0 users would be happy with as.is=TRUE as the default in type.convert. I'm happy to work on the patch and run tests if that is helpful. Cheers, Arni

...() the three-dimensional and two-dimensional objects, but drop() does nothing to the one-dimensional array. Instead, it takes an unintuitive combination of methods to convert a single-dimensional to a vector, while retaining its names. Or I may well be missing something obvious.

Hi all, I am trying to get to the bottom of a strange rsync performance problem. On a specific guest OS, and only on this guest OS, rsync is giving modem-like transfer speeds. This happens on delta transfers, and whole file transfers.

The lack of a function to do this is felt, both when teaching introductory R courses, and when using sapply() or the like.

Hi all... How do i set U32 to filter a port range, instead of a single port? In normal use: source port 80 we use: "... match ip sport 80 0xffff ..." - I know that is something about the 0xffff parameter.... I need to filter ports 1 ~ 1024 to a higher priority class... i tried with IPTABLES MARK and TC FW, but it''s not working.... (...) # iptables -t mangle -A PREROUTING -p

Hi all, I would like to propose the attached function ASCIIfy() to be added to the 'tools' package. Non-ASCII characters in character vectors can be problematic for R packages, but sometimes they cannot be avoided. To make packages portable and build without 'R CMD check' warnings, my solution has been to convert problematic characters in functions and datasets to escaped ASCII, so plot(1,main="S?o Paulo") becomes plot(1,main="S\u00e3o Paulo"). The showNonASCII() function in package:tools is helpful to identify R source files where characters shoul...

In the best case, this might be worth a short note in the Journal of Statistical Software. Thanks for your time, Arni P.S.
