Dear List-Members, I am plotting a barplot with the lattice package. The code works, but when I execute the same code in a for-loop no plot is shown. Can't figure what the problem is. (Maybe I am missing something here, but I tried it with plot device pdf, calling windows() or X11(), testing on windows and linux, etc.) INFO: R version 2.9.1 (2009-06-26) using Windows/RGui require(lattice)

I'm trying to get a reference to this object in C SWX.RET[1:6,c("SBI,"SPI","SII")] While i am able to access and use a plain SWX.RET object, I'm getting confused on how to create an object with the array subscripts like above. Here is what I tried to do. It doesn't work because "[" is obviously not an operation or function on SWX.RET. So how do I

Hi all, I'm putting together some common code + data into a custom package, everything is working out fine, but the ``R CMD INSTALL MyPackage`` call seems to take a particularly long time in the "**data" step: $ R CMD INSTALL MyPackage/ * installing to library ?/Library/Frameworks/R.framework/Resources/ library? * installing *source* package ? MyPackage? ... ** R ** data

Hello! I am running a "for" loop. In the loop I am producing some intermediary results and asking R to print it (of the type below). However, I noticed - when the task is complicated and takes a lot of time, R does not print those intermediary results immediately, but prints them in batches - or does not print at all until we are done with the whole calculation. Is there any way to

The Rd.sty LaTeX package is used when building the R manuals, and by the LaTeX pages produced from the man pages. I have tracked down some problems G?bor Cs?rdi was having recently (see "Re: [R] preformatted and '#' in manual pages" in R-help) to a LaTeX problem, and am trying to work out how to fix it. Specifically, the .Rd file he was using had a structure like \dQuote{

Hi, Our discussions about 64 bit R has led me to another thought. I have a nice dual core 3.0 chip inside my Linux Box (Running Fedora 11.) Is there a version of R that would take advantage of BOTH cores?? (Watching my system performance meter now is interesting, Running R will hold a single core at 100% perfectly, but the other core sites idle.) Thanks! -- Noah

Dear All, Can someone please guide me how to get the certain part from a long html language? e.g. "<td><a href='2005-01.html'>2005-01</a></td><td><a href='2006-01.html'>2006-01</a></td><td><a href='2007-01.html'>2007-01</a></td><td><a

Hello, Is it possible to have the effect of UserDefinedDatabase outside of "attached" environments ? Can I disguise an environment of the sys.frames() as a UserDefinedDatabase ? This seems to suggest that it might be possible : > f <- function(){ e <- environment(); class(e) <- "UserDefinedDatabase"; ff } > f() *** caught segfault *** address (nil),

Hello, Today, Brian Ripley commited the revision 50000 of R's svn repository.

Hello, I'm trying to use the limited connections api defined in Rinternals.h. I have code that looks like this (inspired from do_serializeToConn) : SEXP serialize_to_connection( SEXP xp, SEXP connection ){ Rconnection con ; struct R_outpstream_st out; R_pstream_format_t type = R_pstream_binary_format ; SEXP (*hook)(SEXP, SEXP) = NULL ; con = getConnection(Rf_asInteger(connection));

Well here is one more brain-teaser related to assigning stuff into a list of list. What if I need to create a new list of empty lists? I have actually got a solution to this problem: l = list(list()) for ( i in sequence(length-1) ) { l = list(unlist(l,recursive=FALSE), list()) } But it is not very neat to do this in a loop. Are there any cuter ways to do this?

Full_Name: Mike Danilov Version: 2.9.0 OS: Fedora Core 9 Submission from: (NULL) (142.103.121.198) When checking for the symmetry of a matrix, function isSymmetric.matrix() gets confused by the discrepancy of colnames/rownames if its argument. See the code snippet below. Perhaps it's a problem of the matrix product which copies colnames of the first argument but not the rownames of the
