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, Just wondering why there is "isTRUE" and not "isFALSE".

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));

Hello, Today, Brian Ripley commited the revision 50000 of R's svn repository. I took this as an opportunity to do some data analysis of the log and posted some code and graphics on my blog: http://romainfrancois.blog.free.fr/index.php?post/2009/10/09/celebrating-R-commit-50000 The plots of the number of commits per day (and per month) indicates a peak in 2002.

Hello, When using recover, the called from information is always "eval(expr, envir, enclos)", which is not particularly useful. > f <- function( ){ g <- function(){ stop( "ouch") }; g() } > options( error = recover ) > f() Error in g() : ouch Enter a frame number, or 0 to exit 1: f() 2: g() Selection: 1 Called from: eval(expr, envir, enclos) I'm

Hi, It seems that promptMethods() was changed in revision 44805 to include a call to "isGenericFunction" that at least as of revision 44861 does not exist as far as I can tell. This results in: could not find function "isGenericFunction" when evaluating e.g. promptMethods("myGeneric") Thanks, Michael [[alternative HTML version deleted]]

... and also all objects that actually live in the .GenericArgsEnv environment. > all( sapply( ls( .GenericArgsEnv ), function(.) is.null(environment(.)) ) ) [1] TRUE This has the consequence preventing argsAnywhere to get the args of seq.int. > argsAnywhere( seq.int ) Error in exists(".packageName", envir = envir, inherits = FALSE) : use of NULL environment is defunct

library(some_library_name) Suppose I load a library. I'm wondering what command I should use to list all the functions, classes and variables defined in the library.

Hi All, I am trying to install the package rjags into a local library on a machine for which I do not have root permissions. Using the command: R CMD INSTALL --configure-args="--with-jags-include= ${JAGSBIN}/include/JAGS --with-jags-lib=${JAGSBIN}/lib/ --with-jags- modules=${JAGSBIN}/lib/JAGS/modules" CMD INSTALL -l ${JAGSBIN}/lib/ ../ rjags_1.0.3-12.tar.gz Where ${JAGSBIN} is

I am another person who has had trouble documenting S4 classes and (particularly) methods. The methods package itself is pretty cool by the way, but it is a pity that there are as yet no guidelines on S4 in the "Writing R Extensions" document. I have actually put together a guide on S4 documentation myself for the use of my own lab which is at

Dear List, I'm struggling with the signature writing cbind/rbind functions for a S4 class. First of all, I'm very happy that it is now possible to dispatch on ... I follow the example for "paste" in ?dotMethods, which works as far as this: ### start example setClass ("cbtest", representation = representation (data = "data.frame"),

Colleagues, I am using R (2.9.2, all platforms) to search for a complicated text string using regular expressions. I would appreciate any help you can provide. The string consists of the following elements: SOMEWORDWITHNOSPACES any number of spaces and/or tabs ( any number of spaces and/or tabs integer any number of spaces and/or tabs ) Examples include: WORD ( 123 ) WORD(1 )

Hello, I wrote a package, which in the NAMESPACE file exports functions like this: exportPattern("^\\rh") On R-2.8 (Linux, 64), upon loading the package I have the rh functions present. On R-2.10, Mac OS X, (32 bit), it builds, loads, but the functions are not loaded, i.e the only function is rhyper (which is not from my package). Is there something wrong with my package setup?

Hi, When using lapply (or sapply) to loop over a list, can I somehow access the index of the list from inside the function? A trivial example: df1 <- split( x=rnorm(n=100, sd=seq(from=1, to=10, each=10)), f=letters[seq(from=1, to=10, each=10)] ) str(df1) #List of 10 # $ a: num [1:10] -0.801 0.418 1.451 -0.554 -0.578 ... # $ b: num [1:10] -2.464 0.279 4.099 -2.483 1.921 ... # $ c: num

Hi, I think this is a bug (even though I can't find documentation explicitly saying that it should work). Basically, Rf_PrintValue(obj) fails when 'obj' is an S4 object that should be printed using show() rather than print(). From the error message I'm guessing that the need to use show is detected correctly but then show is not found. "cbind2" in the code below is just

Hi! I have renamed some functions and deleted others. I have noticed that R CMD check complains only about newly added functions, but documented non-anymore-existing functions seem not to matter. I knew about prompt and promptMethods promptClass. They are extremely useful if you are starting to write a package. But what with existing packages that have to be rewritten? Having code and

The methods package ?cbind2 includes the instruction to use via methods:::bind_activation(TRUE). This changes the default definition of cbind globally, disrupting proper evaluation in packages not using cbind2. Is cbind2 a hold-over from a time when ... could not be used for dispatch? What is a safe way for a package to use cbind2? This came up in the context of complex package dependencies
