Dear R developers, I asked this question in r-help list but have not got a definite solution yet, and I think it might be more appropriate to ask developers or CRAN maintainers directly. Many software packages often have a menu item like "Check for updates" under the "Help" menu, e.g. Filezilla and Firefox, and I believe it is also necessary for R (at least for R GUI under

Hi, The animation package 2.0-0 is on CRAN now. This version is a milestone of the animation package. It includes a new function saveHTML() which uses a much more elegant interface and is consistent in syntax with other save*() functions such as saveMovie(), saveSWF() and saveLatex(). Lots of demos have been added to demonstrate the flexibility of this package, e.g. now we can get the snapshots

Hi, Recently I noticed file.copy() would discard the file mode information. Is this the expected behaviour or a bug for file.copy()? > file.create('testfile') [1] TRUE > file.info('testfile') size isdir mode mtime ctime testfile 0 FALSE 644 2011-03-05 17:06:39 2011-03-05 17:06:39 atime uid gid uname grname

Hi, I got this working. i had to get rid of an underscore in one of my variable names to work on RWeb. Thanks for your help though!! Natalie __________________ I think you have to be either honest or careful, since the code you submitted to Rweb is different with your former code! Why the condition was changed from "test<-subset(X, GRADE == 7 & Y_Q10A < 9)" to

Hi, Suppose I have x = parse(text = " {y=50+50+50#'asfasf' } ") now x is an expression with some src attributes. > x expression({y=50+50+50#'asfasf' }) attr(,"srcfile") <text> attr(,"wholeSrcref") {y=50+50+50#'asfasf' } My question is, how can I get my string back (the string passed to parse() as the text argument)? >

Hi, A Windows user asked me a question and I believe this is a bug of R 3.0.0 under Windows: > plot(1:10) > savePlot('test.wmf') Error in .External(C_savePlot, device, filename, type, restoreConsole) : Incorrect number of arguments (4), expecting 3 for 'savePlot' > sessionInfo() R version 3.0.0 (2013-04-03) Platform: x86_64-w64-mingw32/x64 (64-bit) locale: [1]

Hi all, Since roxygen is a great help to document R packages, I am wondering if there exists an approach to go back from the raw Rd files to roxygen-documentation? E.g. turn "\author{Somebody}" into "@author Somebody". This sounds ridiculous, but I believe it helps in the long term for me to maintain R packages. Thanks! Regards, Yihui -- Yihui Xie <xieyihui at

Hi, I observed a slight problem in deparse(): it will add spaces around most operators except /. I wonder if this is easy to fix. I know this is quite trivial, but I will appreciate if / is not treated as an exception. Examples: > deparse(expression(1/1)) [1] "expression(1/1)" > deparse(expression(1+1)) [1] "expression(1 + 1)" > deparse(expression(1%in%1)) [1]

Hi, I'm aware of the definition of a "valid filename" in .SweaveValidFilenameRegexp, but I think it might be better to quote the filename when it contains spaces instead of just giving a warning. This should bring us safer LaTeX code (although I never use spaces in paths). Here is the simple patch: Index: src/library/utils/R/SweaveDrivers.R

Hi, A new package Rd2roxygen has been released on CRAN: http://cran.r-project.org/package=Rd2roxygen (source package available; binaries to come) This package can be useful for developers who used to document their functions in the raw Rd files but want to switch to roxygen now using inline roxygen comments (e.g. me). The main functionality of this package is to parse the Rd files under the

The knitr package was designed to be a transparent engine for dynamic report generation with R, solve some long-standing problems in Sweave, and combine features in other add-on packages into one package. It is a general-purpose package, and currently supports LaTeX, HTML and Markdown (still extensible). See the package website [1] to get started; see the package manuals ([2], [3] and [4]) for a
