Documentation: format of read.table help text (PR#14180)
-----Original Message----- From: r-devel-bounces at r-project.org [mailto:r-devel-bounces at r-project.org] On Behalf Of henrik.parn at bio.ntnu.no Sent: Monday, January 11, 2010 7:10 AM To: r-devel at stat.math.ethz.ch Cc: R-bugs at r-project.org Subject: [Rd] Documentation: format of read.table help text (PR#14180) Dear R developers, I find the format of descriptions of the arguments in the read.table help text slightly inconsistent. For example, the logical arguments comes in seven different formats, more or less explicit about the consequences of a TRUE (or FALSE): 1. check.names logical. If TRUE then the names... 2. blank.lines.skip logical: if TRUE blank lines... 3. flush logical: if TRUE, scan... 4. header a logical value indicating whether... 5. allowEscapes logical. Should C-style [...] ? 6. stringsAsFactors logical: should character [...] ? 7. strip.white logical. Used only when... First, I believe that a consistent style would make the help text easier to follow. Second, I believe that an explicit style (sth like: "logical. If TRUE/FALSE then...") is more intuitive
It would also be nice if the argument description indicated if the argument should have length one or if it could be a general vector. E.g. a style guide could say the default is that arguments are general vectors but that stringsAsFactors logical scalar. If TRUE ... would tell us that stringsAsFactors had to be of length one (so you cannot say that some columns are to be factors and others not). The code phrase could be '<type> scalar' or 'a <type>' but having a common phrase would help. Bill Dunlap Spotfire, TIBCO Software wdunlap tibco.com
and thus preferable over the other styles. This might apply to other help pages as well. I fully understand that the choice of style in help text is a matter of taste and not of very high priority. Nevertheless, I just wish to mention it as a potential for improvement. Thank you for your great work with R!
