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,

Dear Martin, Thank you for the well-reasoned response. I realized I was rather late to make this suggestion for 4.0.0, changing a somewhat low-level function that can indeed affect packages. I was just reviewing some R user scripts that were using type.convert(), mainly on data frames. In all cases, people were passing as.is=TRUE, so I was reminded that I would not be the only user who would

...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.

If read.table() is defaulting to "character" instead of "factor" data type, shouldn't type.convert() also default to "character" in R 4.0.0? This would seem like 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

Hi Simon, thank you for the concise reply. Do you mean the reported behavior of drop() is not a bug? It looks like a borderline bug to me (see below), but I'm not the judge of that. If this is the intended behavior and serves an actual purpose, then that could be explicitly documented in a \note{} on the help page. Such a note would slightly reduce the surprise of users running into this

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.

Hi, I am building my own TCP daemon for easing some routine admin stuff... I am no expert on security,. I would really appreciate it if someone sent me some pointers to writing TCP daemons that are hacker-proof( i know there is nothing like that...but I do not want to be making mistakes in coding that are well known.. ;) The daemon runs as root....so that is why I am woried.... Thx, Arni

One descriptive statistic that is conspicuously missing from core R is the statistical mode - the most frequent value in a discrete distribution. I would like to propose adding the attached 'statmode' (or a similar function) to the 'stats' package. Currently, it can be quite cumbersome to calculate the mode of a distribution in R, both for experts and beginners. The lack of a

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

Creating a plot with reverse Y axis is easy enough with traditional graphics: > x <- 1:3 > y <- 1:3 > plot(y~x, ylim=c(3,1)) +-----------+ 1 | o | | | 2 | o | | | 3 | o | +-----------+ 1 2 3 But xyplot doesn't grasp my idea: > xyplot(y~x, ylim=c(3,1)) +-----------+ 3 | o | | | 2 | o |

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

I present you with a function that solves a problem that has bugged me for many years. I think the problem may be general enough to at least consider adding this function, or a revamped version of it, to the 'stats' package, with the other multinomial functions reside. I'm using R to export data to text files, which are input data for an external model written in C++. Parts of the
