Your statement seems innocent enough on the face of it, but there are two facets that I think are worthy of note. The first is that of time, and more specifically who's time. As a user of other lists I can say that this is the best list in terms of getting the answer to my problem, albeit sometime's obliquely. I intermittently respond to questions generally of the type you refer to. I say

Hello R-users, I wanted to generate objects named 'my.ftn1', 'my.ftn2', ... , 'my.ftn10', and tried the following code without success. How can I do this? > for ( i in 1:10 ) { + sub(" ", "", paste("my.ftn", i)) <- NULL + } Error: Target of assignment expands to non-language object > Many thanks. John

Dear R-users, I state that this is for beginners, so you may ignore this in order not to be irritated. By the way, "patience" is another important thing, together with "kindness", we should keep in mind when we teach students and our own children as Jim Lemon pointed out well in the context of the Socratic method. You may know that being kind does not mean giving

Golly, anyone who read Plato's Dialogues would realize that the Socratic method involves patiently leading the questioner stepwise through the solution, not simply writing RTFMeno. Jim

The answer to my question was contained in http://cran.r-project.org/contrib/extra/winedt/ReadMe , although it helped to receive the restatements that were emailed to me. As mentioned by Uwe Ligges, Renuad Lancelot, Niels Waller, my mistake was not starting R before using R-WindEdt. Below I will copy the instructions on using R-WinEdt by Renaud Lancelot (except for the last paragraph which is

Hi R-devels, recently I wanted to quickly look up a C implementation in R-Core code in the official subversion repository; more specifically the code was called from R by means of the .Internal() interface. And: yes, I did read Uwe Ligges' article in R News, R Help Desk: Accessing the sources. R News, 6(4):43-45, October 2006 In the end I succeeded, using grep and the like to search the

File .../src/library/base/man/Random.Rd provides help with title "Random", but there is no line \alias{Random} in that file. If the absence is not intended, I'd suggest to add that line.

I hazard to submit, more people are turning to opensource as XP becomes obsolete.

I rebuilt a test version of my yaImpute package using Uwe Ligges' windows build service.

My subject line refers to a thread from June 2005 where I found explanations from Uwe Ligges and Friedrich Leisch as to what is intended by the R citation recommended within the software. Forgive me if I missed some points within the thread but when I found myself circling through messages I had already read, I stopped trying to follow it. I understand and mostly agree with how the R citation is

For those issues with optimization methods (optim, optimx, and others) I see, a good percentage are because the objective function (or gradient if user-supplied) is mis-coded. However, an almost equal number are due to functions getting into overflow or underflow territory and yielding quantities that the optimization tools cannot handle (NA or Inf etc.) Two general approaches I find helpful: 1)

Uwe, You said you used testdata <- data.frame(date = strptime(c("31121991", "31121991"), "%d%m%Y"), nothing = c(NA, NA)) but that's not the same object, and that one does work for me. > dput(testdata) structure(list(date = structure(c(694137600, 694137600), class = c("POSIXt", "POSIXct")), nothing = c(NA, NA)),

Kurt, Uwe suggested I write to you as maintainer of chron ... at the start of is.weekend, in the check on the argument type, maybe just change chron() to as.chron()? This would ensure as.chron.POSIXt gets called on POSIXt arguments, and (I think) fixes the problem. I tested and it seems ok. No warning/error required. > is.weekend function(x) { if(!inherits(x, "dates"))
