R on the iPhone/iPad? Not so much....a GPL violation
Hi all, There have been posts in the past about R being made available for the iPhone and perhaps more logically now, on the iPad. My recollection is that the hurdle discussed in the past was primarily a lack of access to a CLI on the iPhone's variant of OSX, compelling the development of a GUI interface for R specifically for these devices. R itself, can be successfully compiled with the

Wine err: dosfs:DRIVE_ReadSuperblock The Filesystem is not FAT !!
...t; "Type" = "hd" "Label" = "C" "Device" = "/dev/hda1" "FS" = "win95" I expect this is a problem with my filesystem setup or my OS. This only happened with Mandrake 8.0 - GoLinux and RedHat worked fine. I'm really frotzed in the head over this. Please heal my perception. arnim

wave/OSS and JumpStart Kindergarten...
Warning: WINE Newbie Alert. Proceed with caution.... Background: I don't want to fork up $$$ for a separate Windows machine for my kid so I've decided to see if I can run any of the popular brain-rot software under WINE (Is it "WINE" or "Wine" or "wine"?) on a Linux 2.4.18 kernel.

Thanks! Ranjan

newbie lapply question
Hi -- I just noticed the following (R 2.6.1 on OSX) > lapply(c(as.Date('2007-01-01')), I) [[1]] [1] 13514 This is a bit surprising.. Why does lapply unclass the object? Sorry for such a basic question, I don't seem able to produce the right google keywords. Ranjan

Idioms for empty dataframes
I'm fairly new to R, coming from a programming background -- it's quite nice to work with dataframes, though, as opposed to explicit iteration. One thing I've found, which is surprising is that zero-length dataframes seem to cause errors: > t <- data.frame(bob=c(100)) > order(t$bob) [1] 1 > t1 <- t[t$bob < 50] > order(t1$bob) Error in order(na.last, decreasing,
