Hi, people. ?alist says: 'alist' is like 'list', except in the handling of tagged arguments with no value. As written, this description is misleading. For example: > list(e=3+5) $e [1] 8 > alist(e=3+5) $e 3 + 5 We are not in the situation of tagged arguments with no value, and then, clearly, 'list' and 'alist' behave differently. The 'alist' documentation probably needs to be amended, or clarified. --please do not edit the information below-- Version: platform = i686-pc-linux-gnu arch = i686 os = linux-gnu system = i686, linux-gnu status = Under development (unstable) major = 2 minor = 4.0 year = 2006 month = 05 day = 13 svn rev = 38058 language = R version.string = R version 2.4.0 Under development (unstable) (2006-05-13 r38058) Locale: LC_CTYPE=fr_CA.UTF-8;LC_NUMERIC=C;LC_TIME=fr_CA.UTF-8;LC_COLLATE=fr_CA.UTF-8;LC_MONETARY=fr_CA.UTF-8;LC_MESSAGES=fr_CA.UTF-8;LC_PAPER=fr_CA.UTF-8;LC_NAME=C;LC_ADDRESS=C;LC_TELEPHONE=C;LC_MEASUREMENT=fr_CA.UTF-8;LC_IDENTIFICATION=C Search Path: .GlobalEnv, package:methods, package:stats, package:utils, package:datasets, fp.etc, package:graphics, package:grDevices, Autoloads, package:base -- Fran??ois Pinard pinard.progiciels-bpi.ca
