Please use the CRAN versions, not the ftp versions which are now out-of-date. Both packages are on base CRAN now, but may not have propagated to all mirrors yet. (But thanks to Gerald for responding-- I had de-subscribed from R-help.) For anyone using the HANDY package (a Windows-specific package which includes a non-C DLL, so I can't CRAN it): I'll post an updated version on the ftp site

Version 2.5.1 of 'mvbutils' is now on CRAN. This version offers improved support for easy package preparation and maintenance, plus minor changes required by the new version of the 'debug' package (see separate announcement). Package 'mvbutils' offers the following main features, as well as a number of miscellaneous goodies: - Hierarchical organization of projects (tasks)

You might want to have a look at 'source.mvb' & friends in the 'mvbutils' package. It's designed to allow control of nested sourcing, and to allow interspersed data and commands in a single self-contained file. Unlike 'source', 'source.mvb' reads each statement and immediately executes it, before proceeding to the next; hence it has do the parsing to figure

New versions of the 'mvbutils' and 'debug' packages are now available on CRAN. These should work with R 2.10 as well as R 2.9. 'mvbutils' offers tools for organization of workspaces, function/documentation editing with backups, package construction and updating, seamless per-object lazy-loading, and various miscellaneous goodies. New in this version: nearly-automated

The function 'getAnywhere' crashes if given a non-existent name containing a period: > getAnywhere( 'nomethod.noclassforme') Error in get(x, envir, mode, inherits) : variable "nomethod" was not found However, 'getAnywhere' behaves gracefully if the non-existent name lacks a period: > getAnywhere( 'nomethod') no object named `nomethod' was

Is this the last bug of the year? Well, it's the last one from me, anyway... The "parse" function seems to give erratic behaviour when used in conjunction with "pushBack" on an open connection (R1.6.1, Windows 2000). Try this: > { cat( c( '1', 'a+b', '2'), file='r123.r', sep='\n'); tcon_ file( 'r123.r'); open( tcon);

When replacing all elements of a column in a data.frame, a corrupt data.frame will be generated if the replacer is "short": test> bbb <- data.frame( x=1:2) test> bbb[,'x'] <- 3 # should fill the column test> bbb x 1 3 2 <NA> Warning message: corrupt data frame: columns will be truncated or padded with NAs in: format.data.frame(x, digits = digits)

In R-1.7.1, I used to be able to append a character vector to a 'tklistbox' with e.g. listio <- tklistbox( tktoplevel(), font='Courier', height=20, width=20, setgrid=TRUE) tkinsert( listio, 'end', letters[1:3]) tkpack( listio,side='left', expand=TRUE, fill='both') and three items would be added to 'listio'. This doesn't work in R-devel-- it

Dear list Can anyone suggest a simple way to abort execution like stop(...) does, but without issuing an "Error: ..." message? I don't want to set 'options( show.error.messages=TRUE)' because I want normal behaviour to resume after this particular stop. (Please reply personally as well as to the list, as I'm not subscribed to R-help) Thanks Mark -- Mark Bravington

I've just installed R2.10.0 v50082, and found the problem described below the first few times I launched it. Did not occur with v49613 (the previous most recent version I have). The problem has now gone away, and is therefore non-reproducible, but there seems to be something up with parameter processing or environment variable checking or loading of .RData files immediately after installation.

I'm getting the following warnings under 2.10 v50082 but not v49613 >> In addition: Warning messages: 1: In `[.data.frame`(df, -(1:nrow(df)), , drop = FALSE) : named arguments other than 'drop' are discouraged 5: In `[.data.frame`(object, !omit, , drop = FALSE) : >> named arguments other than 'drop' are discouraged In neither case are there any named arguments,

A bit late for Santa, but on my wish-list nevertheless: is there any chance that "scan" and "readLines" could be extended to take a parameter "until" or "EOF.marker", which would be a character string that (if encountered while reading) would cause the reading to stop, just as if an end-of-file had been found? [But leaving a connection open, so that

Problem below with PCRE grep in R-devel; works fine in R-patched.

There's a problem new to R2.4.0 when rbinding an auto-row-named data.frame to a list: > rbind( data.frame( x=1), list( x=2)) Error in attr(value, "row.names") <- rlabs : row names must be 'character' or 'integer', not 'double' Works OK with 2 data.frames or 2 lists.
