Hi, R people. Consider the following small R session:
======================================================================> > a <- c(8.48, 9.58, 9.96) > stem(a) The decimal point is at the | 8 | 8 | 5 9 | 9 | 6 10 | 0 > stem(round(a,1)) The decimal point is at the | 8 | 5 9 | 9 | 6 10 | 0 ======================================================================< As the output of ?stem is rather vague about the format of its output, some may question whether we have bugs here, or not. If not, let's call what follows mere "suggestions for improvement" :-). The vertical bars are aligned in the second case while they are not in the first. Would not they be nicer if always aligned? Also, while "scale=" could adjusted to elongate or compress the result, the scale is meant to be applied over the "default" scale, the meaning of which is not defined in ?stem. The default scale seemingly uses more lines than really required. Maybe this default could be improved? Here is another strangety about stem(): ======================================================================> > stem(2) > stem(c(2, 2)) The decimal point is at the | 2 | 00 ======================================================================< That is, a single value is not reported, while it probably should. --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 = 06 day = 01 svn rev = 38258 language = R version.string = R version 2.4.0 Under development (unstable) (2006-06-01 r38258) 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:graphics, package:grDevices, package:utils, package:datasets, Autoloads, package:base -- François Pinard http://pinard.progiciels-bpi.ca ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
