Re: [Rd] Installing a Tcl/Tk Extension on OSX
This is relatively simple if you can find the packages you need in the default Tcl/Tk install on the Mac (/System/Library/Tcl) and if these packages are compatibles with the X11 Tcl/Tk used by R. This should be fine for packages containing no compiled code. For the others, you should check first (but for instance, Img and tsl work for me - Mac OS X 10.6.4). You can then use these package in R own Tcl environment like this: library(tcltk) Loading Tcl/Tk interface ... done addTclPath(/System/Library/Tcl) tclRequire(Img) Tcl 1.4 Best, Philippe ..°})) ) ) ) ) ) ( ( ( ( (Prof. Philippe Grosjean ) ) ) ) ) ( ( ( ( (Numerical Ecology of Aquatic Systems ) ) ) ) ) Mons University, Belgium ( ( ( ( ( ..

[Rd] CMD check: checking data for non-ASCII characters is very time consuming
Checking data for non-ASCII characters takes a very long time for packages with substantial data components. Could the check be done manually by the developer, and a switch introduced to optionally skip this during check? __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel

Is that intentional ? An example: Note that the lack of partial matching when performing assignment is also documented. See second last paragraph in Details section of ?Extract Yes, I see, thanks. I looked at ?[.data.frame, where this is not documented. However, given the documentation that partial matching is not used on the left-hand side, I would have expected even more that the assignment sw$Fert[1]- 10 works differently, because I am using it on the left-hand side. Probably, extraction ([1]) is done first here, so that the right-hand side won. At least, this is very confusing. Best, Ulrike This is another example of why it's a good idea to avoid the '$' notation when fiddling with data frames. Try this: sw - swiss[1:5, 1:4] sw[[Fert]] sw[[Fert]] - 10 and my preferred version: sw[, Fert] sw[, Fert] - 10 I've never liked partial matching for data frames. -Peter Ehlers __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
[Rd] S4 Method Signatures
Hello,
If the signature of a method defines which generic it implements then I'm
confused about why this minimal example I invented won't work :
setGeneric(myFun, function(rs, ...){standardGeneric(myFun)})
setGeneric(myFun, function(cs, ...){standardGeneric(myFun)})
setMethod(myFun, numeric, function(rs, colour = Blue)
{
cat(rs*100, colour)
})
setMethod(myFun, character, function(cs, colour = Red)
{
cat(cs, colour)
})
Thanks for any tips,
Dario.

Re: [Rd] Installing a Tcl/Tk Extension on OSX
Thanks, that works actually out of the box from a fresh OSX 10.6 installation. So no ActiveTcl is needed. This is great!
