The paradigm we have been following is to have all the environments saved in individual .rda files, so after loading the package they can be accessed with e.g., ls(), get(), mget() automatically without explicitly having to load() each

Hi all, Most of the analyses I do are short little once-and-done type things that are easily encapsulated in a .Rnw file. However, I sometimes end up with projects that take an extended amount of time. Usually these projects are not easily encapsulated in an .Rnw file, so I have been using a single .R file with lots of comments. The problem with this approach is keeping track of what you have

Dear developeRs, I've searched the documentation, FAQ, and mailing lists, but haven't found the answer(*) to the following: When should one specify LazyLoad, LazyData, and ZipData? And what is the default if they are left unspecified? (*)Except that 1) If the package you are writing uses the methods package, specify LazyLoad: yes, and 2) The optional ZipData field controls whether the

On Solaris when my package is built, I get the following result: creating vignettes ...Segmentation Fault - core dumped OK My question isn't why I get a segfault, but why does build return an OK after such an inauspicious event? Is build only supposed to error out if something more central to the package is off? R CMD check does issue a warning that the vignette is missing, so maybe that

> R.version.string [1] "R version 2.1.0, 2005-03-17" I don't see anything in either https://svn.r-project.org/R/trunk/NEWS or in the Changes file for R-2.1.0 about changes in package.skeleton() (nor in the help page), but when I run this function, all the .Rd files produced are of the data format even if all I have in my .GlobalEnv are functions. A trivial example is to run the

Hi, On Windows, package files in the inst/ subdir are installed after the lazyload creation. This differs from Linux where inst/ is installed _before_ lazyload creation. Since packages may need data in inst, I think the order on Windows should be changed. Perhaps like this: diff --git a/src/gnuwin32/MakePkg b/src/gnuwin32/MakePkg index 57af321..868e8f1 100644 --- a/src/gnuwin32/MakePkg +++

I just built R-devel from source on OS X (Tiger), using the subversion sources. Running ./tools/rsync-recommended didn't download rcompgen. I checked http://cran.r-project/src/contrib/2.7.0/Recommended and indeed, this package is not there. If I try to install using install.packages I get > install.packages("rcompgen", type="source") --- Please select a CRAN

The function knn.cv in the class package doesn't have error checking to ensure that the length of the classlabel argument is equal to the number of rows in the test set. If the classlabel is short, the result is often a segfault. > library(class) > dat <- matrix(rnorm(1000), nrow=10) > cl <- c(rep(1,5), rep(2,5)) > cl2 <- c(rep(1,5), rep(2,4)) > knn.cv(dat, cl) [1] 2

Hola! I got past the problems I asked about two days ago, thanks. No I am updating CRAN package asypow (the daily package check on CRAN gave warnings due to .Rd problems, fixed). Now it PASSED Rcmd check (WindowsXP home edition, rw2000dev, on a new toshiba laptop, if that matters.) but then Rcmd build --binary gives problems: . . . preparing package asypow for lazy loading Error in

Is there a global option somewhere that can completely disable the LazyLoad option? I want all my packages in source format for searching purposes, crippled by the conversion to database format. ---------------------------------------------------------- SIGSIG -- signature too long (core dumped)

Hi, I suddenly started getting strange errors while working on my caTools package: >RCMD install C:/programs/R/rw2011/src/library/caTools ...... preparing package caTools for lazy loading Error in file(file, "r", encoding = encoding) : all connections are in use Execution halted make: *** [lazyload] Error 1 *** Installation of caTools failed *** I searched

If one wants to unload compiled code for a package containing a namespace, my understanding is that .onUnload() should be used, with a call to library.dynam.unload(). This is used in e.g., the stats and methods packages, but it appears to me that the compiled code is not being unloaded when the package is detached(). Am I misunderstanding something? Best, Jim > search() [1]

I added a new data file, NLSY.RData, to a package that uses LazyData: Yes It passed R CRAN check and R CMD install worked w/o significant complaints. * installing to library 'C:/R/R-2.15.2/library' * installing *source* package 'heplots' ... ** R ** data ** moving datasets to lazyload DB ** demo ** inst ** preparing package for lazy loading Warning: package 'nnet' was

Prior to R-3.6.0 the keys in the lazyload key files, e.g. pkg/data/Rdata.rdx or pkg/R/pkg.rdx, seemed to all be 2-long integer vectors. Now they can be lists. The ones I have seen have two components, "eagerKey" is a 2-long integer vector and "lazyKeys" is a named list of 2-long integer vectors. > rdx <- readRDS(system.file(package="survival",

Hi all, I'm struggling a bit to get pgfSweave to lazyload objects when compiling a .Rnw file for a second time. Caching works fine except that for every run all objects get cached again and again. I've used cacheSweave which works fine; all cached objects from code-chunks with option cache = TRUE are lazy loaded. I've tried it on two machines ... I'm pretty sure I'm

I get a segfault when using savePlot("foo","pdf").

Using R-1.8.0 (d/l and compiled on 2003-10-01) on WinXP, I seem to be unable to determine the maximum memory allocated to R. The help still says to use memory.limit(size=NA), but this returns the value NA. In addition, I have set --max-mem-size=2G but I run out of memory somewhere around 500Mb (which is why I am trying to find out how much memory is allocated). I don't have any other programs

Hi, I have a package that contains two vignettes that both use saved objects in the examples directory of the package. With previous versions of R I could have a code chunk in the vignette like this: <<echo=false>>= load("../examples/somedata.Rdata") @ followed by a code chunk like <<eval=false>>= foo <- bar("data") @ that simulated the actual

Hi all, In the CHANGES file for R-2.3.0alpha, there is the following statement: winMenuAdd() now has no limits on the number of menus or items, and names are now limited to 500 (not 50) bytes. However, I can reproducibly get a segfault using this (admittedly silly) example: for( i in 1:5) winMenuAdd(paste("Test", letters[i], sep="")) for(i in 1:5) for(j in 1:24)

Hi All, I am having a problem with Rcmd build using R-devel on WinXP. If I try to build a package using the --binary flag, I get the following error: Error: cannot change to directory ' 'c:/TEMP/Rbuild.XXXX' ' Where XXXX is some number. I can get Rcmd build to work using R-1.7.1 and R-1.8.0, so I don't think it is a permission problem. I looked at the build file, and the
