I can crash R CMD check with the following message: This shouldn't happen at /usr/local/lib/R/share/perl/R/Rdconv.pm line 1226, <rdfile> line 24. under the following circumstances -- an \itemize{} environment in the \details{} section with an item that continues on more than one line, delimited by curly brackets. It looks like \items would rather be delimited by spaces than by curly brackets. This isn't clear from the R-exts manual (p. 15), which says: The \itemize and \enumerate commands take a single argument, within which there may be one or more \item commands. The text following each \item is formatted as one or more paragraphs, suitably indented and with the first paragraph marked with a bullet point (\itemize) or a number (\enumerate). I was misled by the analogy with LaTeX, where you would delimit \item by curly brackets. The workaround is easy -- just delimit by spaces instead of curly brackets -- but in any case, it seems that a "This shouldn't happen ..." message shouldn't be visible to the user ... example: \name{test} \alias{test} \title{test} \description{test} \usage{ test(x) } \arguments{ \item{x}{test} } \details{ Criteria: \itemize{ \item{test: this is an item that is quite long quite long quite long quite long and continues on another line} \item{test2} \item{test3} } } \value{ test } \author{Ben Bolker} \keyword{misc} -------------------- --please do not edit the information below-- Version: platform = i686-pc-linux-gnu arch = i686 os = linux-gnu system = i686, linux-gnu status = major = 1 minor = 4.1 year = 2002 month = 01 day = 30 language = R Search Path: .GlobalEnv, package:ctest, Autoloads, package:base -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-devel mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
