That looks like a bug in the latticeExtra

This is completely undocumented use of options, but it does cause a segfault with r-patched and r-devel on Linux: options(list('digits', 'scipen')) Strangely enough, options(list('digits')) and options(list(digits = 10, scipen = 2)) work as might be expected. Deepayan

The warning message in the last line of this email is incorrect.

OK. Sorry to have bothered you. It may well have been the namespace issue, a subtlety that I would have been unaware of. Thanks. I've cc'ed this to r-bugs in case there is anything they wish to do about it. -- Bert Gunter > -----Original Message----- > From: Deepayan Sarkar [mailto:deepayan@stat.wisc.edu] > Sent: Wednesday, December 15, 2004 12:05 PM > To: Berton Gunter

Hi, I recently made changes to lattice code which needed changes in many man pages as well. Before I made the appropriate changes, R CMD check was flagging most of the problems correctly, except for the man page for tmd. I have created a toy package that shows this, available at http://www.stat.wisc.edu/~deepayan/R/tmdprob_0.12-2.tar.gz This passes R CMD check on R 2.1.0 and r-devel from August

I'm seeing inconsistent symbols from the same expression with the following code: expr = expression(sum(x, 1, n)) plot(1, main = expr, type = "n") text(1, 1, expr) Moreover, the inconsistency is reversed in r-devel compared to R 2.0.1. In particular, the main label shows a \bigoplus instead of \sum in r-devel, and the other way round in 2.0.1. demo(plotmath) shows \sum in

Hi, I'm trying to understand whether the use of substitute() is appropriate/documented for plotmath annotation. The following two calls give the same results: > plot(1:10, main = expression(alpha == 1)) > do.call(plot, list(1:10, main = expression(alpha == 1))) But not these two: > plot(1:10, main = substitute(alpha == a, list(a = 2))) > do.call(plot, list(1:10, main =

Hi all, I have a very high dimensional data and apparently there are several columns that contain similar information (some columns are equal). I want to form a matrix/data frame consisting of unique columns. Does anyone have an efficient way of getting out these columns. A small section of the data frame is given below. Thanks for helping.

Hi, Many of the complaints about lattice stem from the default settings (a.k.a. theme) on screen devices, which has a grey background. It's easy enough to change this, even pseudo-permanently through a startup script, so this is not a serious problem. However, there's one situation where this has an unfortunate effect: on Windows, someone might 1. create a plot (on screen) 2. right click

Every time I try and add a user to samba using 'smbpasswd -a -m meuser' I get the following error messages: Bind failed: Inappropriate authentication Bind failed: Inappropriate authentication Failed to add entry for user meuser.
