Version 1.2.2 of 'debug' is now on CRAN. The debugging facilities offered include code display, graceful error recovery, line-numbered conditional breakpoints, access to exit code, flow control, and full keyboard input. The new version supports debugging of...

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...

Hi The link from CRAN to "new features in R-devel" hasn't been working for a few days. Specifically, there is no NEWS file in https://svn.r-project.org/R/trunk/, though there is an ONEWS. The link...

The following looks like an 'eapply' bug to me: t/subtest> e <- new.env() t/subtest> e$tempo <- quote( 1+'hi') t/subtest> lapply( ls( e), function( x) length( get( x,e))) [[1]] [1] 3 # seems reasonable-- e$tempo is...

PS correction to previous my email, where I wrote the 2nd part before the 1st part: Places to mention "readme.packages": #(3) And presumably in "Writing R Extensions" itself, if #"readme.packages" is #likely to be a semi-permanent feature...

G'day There's a bug in R-devel help() when something is documented in multiple places. Eg > library( gmp) > ?apply The browser window then contains: Error in length(packages):"Help on topic '%s' was found in the following package...

Dear R-devel I'm experimenting with easy-to-use ways for a package maintainer to modify a"live" package-- i.e. while it's loaded & in use. One difficulty is that packages with namespaces are usually sealed with 'lockEnvironment...

A while ago Luke Tierney remarked that the warning associated with 'makeActiveBinding'-- "saved workspaces with active bindings may not work properly when loaded into older versions of R"-- should probably be removed in R-devel. It's still cropping up...

There is a new version of the 'debug' package (v1.1.0) available on CRAN. For existing users, the main changes are (i) some bug fixes, and (ii) it is now NAMESPACEd, so you can avoid naming conflicts with other...

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...

'update.default( x, ...)' checks for a component of 'x' named 'call' and gives up if there isn't one. Before giving up, how about checking for an attribute named 'call'? I.E. something like this: # Existing code: call <- object$call...

Hi Andre Just saw your email; I'm the author of the 'debug' package but I don't subscribe to R-help, so it's best to email me directly with questions about 'debug' or 'mvbutils'. The quick answer is...
