similar to: obstacles to using vectors with attributes

Hi all, I am having trouble extending S4 classes in cases where I'm using both validity and initialize methods. I've read as much S4 information as I can find, but I've yet to have that "a-ha" moment. In my application, I am using validity methods to guard against inappropriate input data that my code has no way of handling, and initialize methods to detect and deal

Hi all, Using character indexing on a vector is quite fast up through vector length of 46340, then it suddenly it gets 3 orders of magnitude slower. This is true at least of the special case in which the index vector is the complete (though possibly out-of-order) set of vector names: test <- function(n) { vec <- seq_len(n) names(vec) <- as.character(vec) ind <-

In R 2.15.2 (and not before), in the definition of function 'diffinv.vector' in package stats, there is difference <- as.integer(differences) I believe differences <- as.integer(differences) is intended, because 'difference' is not referenced anywhere. However, without conversion of 'differences' to integer, 'diffinv.vector' in R 2.15.2 works OK. Also,

Hello R-users, during one of my analyses that involve a SVD, I get the following error message: Error in La.svd(x, nu, nv, method) : error code 1 from Lapack routine dgesdd With a search on the R web site, I only found references to error codes 17 and 3 for this particular routine. I also found the Lapack web site, but could not find a list of the possible error messages. If somebody knows what

It appears that "break" will break from the outermost enclosing loop not the innermost loop. Is it a bug or language feature? Tim -- Timothy H.

A preliminary release of my postgres package for R is at http://www.nceas.ucsb.edu/~keitt/R/postgres.tgz It allows one to read and write data frames to and from a postgres database, execute queries and has an experimental "proxy" interface that allows you to access postgres tables using the standard, local data frame model. All accesses to the data frame generate the appropriate

Good evening, I recently have observed slow merges when combining multiple data frames derived from DataFrame and base::data.frame. I observed that the index column of intermediate tables was of class <AsIs> (automatically converted from character). The problem occurred mainly when using the sorted = T option in base::merge. This can be traced to xtfrm.AsIs being more than 100 times slower

The current INSTALL script calls ./configure if it exists when installing packages, but does not check the return value from configure. I have my configure script abort under certain conditions and it would be nice if the INSTALL script would stop at that point. Also, is there an autoconf macro for testing for gnu make?

I've rolled up R-1.9.1.tgz a short while ago. This is a maintenance version mainly to fix a number of minor bugs and issues (the most annoying one seems to have been the change to barplots of tables) and some installation issues. Because of the relocation the CVS archives, there is no direct access to the files until they show up on the CRAN master site. You can then get it from

I'd like to suggest a small feature be added to R. It would be nice if "load" and "save" had function hooks for object initialization and finalization, e.g., load.hook <- function(x) UseMethod("load.hook") save.hook <- function(x) UseMethod("save.hook") These would then be called on each object saved or loaded. The default method would do

Hello, I am trying to use lmLists in the lme4 package and copying over very standard code from the nlme package given in 'Mixed-Effects Models in S and S-Plus'. It appears to not accept an 'I(age-11)' in the formula, though it will accept the formula with out the subtraction of 11 from age. This seems like it would be a bug, since this is standard formula syntax, unless

Congrats on the new release. The new package management tools are great! A couple of quick comments: 1) it might be nice to add an optional "Autoloads:" field to the description (the package does not depend on these other packages, but will autoload them if certain functions are called). 2) on page 3 of the R-exts document, it says to set PKG_* flags in 'Makeconf'; I think

class(o)[!inherits(o,"AsIs")] is still in function 'get_all_vars' in R patched (in https://svn.r-project.org/R/branches/R-3-6-branch/src/library/stats/R/models.R).
