Further to my previous post, it would be possible to create an .exe file, say: my_r_application.exe That starts R, loads your R package(s), calls the R function of your choice and does whatever else you want. However, I don't think that it would add much value. But feel free to correct me if you think that I'm wrong. [[alternative HTML version deleted]]

Creating an .exe file isn't necessarily difficult. The main problems are that you have to write and compile the C (or other) files. Otherwise, the complexity depends on the level of Inter Process Communication that's required. Simply starting R with some initial conditions, is easy. Even if you want to prompt the user to install missing packages, it isn't necessarily difficult. It

Hi Z I think supporting HCL color spaces more, is a *very* good idea. However, I doubt many R users, understand the motivation for HCL color spaces. I've reproduced Ross Ihaka's notes on color, on my personal website: https://sites.google.com/site/spurdlea/exts/ihaka_r_stats_787_10_color.pdf (This has been reproduced with permission). Another good article is: https://www.r-project.org/conferences/DSC-2003/Proceedings/Ihaka.pdf And the colorspace package vignette is also a good resource: https://cran.r-project.org/web/packages/colorspace/vignett...

However, I don't think that a lack of zip formats, is a disincentive from using R. If you have an issue with the Windows installer, the obvious option is to install the source version, and compile from it. This is, after all, how open source is

False, sorry. Wrapping != Defining a New Class. And you don't have to define any methods. However, my understanding of your original post is that you want to modify

I've just discovered that Rtools (on Windows) contains Python interpreter(s). I'm assuming that Python is required to build R packages, on all operating systems. I think this is a mistake. Also, by my count, Rtools contains six Python interpreters. I've miscounted, I hope... [[alternative HTML version deleted]]

<polite mode> > x %inherits% "data.frame" IMHO, I think that user-defined binary operators are being over-used within the R community. I don't think that they're "cute" or stylish. I think their use should be limited to cases, where they significantly increase the readability of the code. However, readability, is a (partly) subjective topic...

Do you just need something on pen and paper? (In which case, I don't see why it needs to be "standard"). Or do you need something that can be used with bison/yacc/cup/etc to produce a parser? On a side note, I would say that the R Language Definition is the "standard" way. But I do recognize that this has a different flavour to modern language implementation *theory*.
